Hello Fred,
Used a Inch Pounds torque wrench. Battery terminals range in torque from 50
to 105 inch pounds. Go to the
www.trojanbattery.com/Tech-Support/BatteryMaintenance.aspx<http://www.trojanbattery.com/Tech-Support/BatteryMaintenance.aspx>
for what torque
value is use for your batteries.
In using a torque wrench in a battery compartment, slip on some pipe foam
insulation over the handle and tape it on so you do not short between two
battery terminals.
It is best to torque the battery terminals when first installing them.
Drive the EV five miles and re-torque again. You will find that you will
loss about 5 inch lbs on the first 5 miles. Then recheck again at 10 miles,
if you only loss about 1 inch lb, then check again at 50 miles.
If the battery terminals start to maintain about a steady torque of 1 inch
lb per 100 miles, than you can calculated when you will have to check them
again.
The problem with lead post, is that the battery clamp shrinks the post and
some may even pucker or mushroom out the top. I solve this problem by using
a plated brass battery clamp plus use a stainless steel washer on the
battery top stud and install a SS lock washer and nut to put down ward
pressure on the battery clamp.
After about four years of initial installation, I still maintain a 75 inch
pounds of torque on my Trojan T-145's.

Hey Shawn!
That sounds great! Can't wait to see it when it's done.
Shawn's creations are always a crowd pleaser at the Power of DC. I
know, Elmer, the track owner and owner of an Exxon station, has told
me he's been impressed with OJ and enjoys seeing it run.

Chip,
Sounds great. We are working hard to have "Juiced Up" ready for the
race. AGNuS is getting a voltage boost, a new controller, a street
front tire to replace the knobby, and will be ready to go. I going

The 2007 Power of DC will be June 2-3, 2007 in Hagerstown, Maryland
This year we are going all the way and will have an EV AutoCross,
ScooterCross, Range Rally, Show-n-Shine, and our classic NEDRA Power
of DC drag race all held in beautiful Western Maryland thanks to the
efforts of Mike Harvey and wife Tracy.
On Saturday June 2 is the AutoCross, ScooterCross, Range Rally and
Show-n-Shine. The AutoCross will be held at Hagerstown Community
College. Tracy has also layed out an 8.5 mile Range Rally Event held
near the campus.
Then on Sunday June 3 is our Classic NEDRA Power of DC Drag Race to
be held at Mason-Dixon Dragway.
There is no cost to enter the AutoCross and other EVents on Saturday,
however donations are appreciated. Cost to enter the drag strip on
Sunday is $25.00 which is the Mason-Dixon Dragway entry fee.
We are also going to have a Dinner and Reception. Trophies will be
awarded to the winners. We will have a raffle and Jim Husted is
donating one of his famous 6.7 inch motors.

Why the 60/40 ratio. I've always just used a little tounge weight. Is it
because of the weight shift on hills? Lawrence Rhodes....

I live in the Seattle area and we have a handful of EVs (4 S10EVs and 2
RAV4EVs) that would benefit from a small network of Inductive MagneChargers
laying around the city.
The RAV4EVs need the Small Paddle Inducting chargers, and we have enough
SPI-to-LPI converters for the S10EVs.
We have 7-9 LPI MagneChargers for the city, but no SPI MagneChargers.
Basically, any SPI EV drivers are out of luck, and the LPI EV drivers would
like to help them out.
Does anyone know where we can obtain SPI MagneChargers?
Ideally these would be working unused chargers that people would be willing
to donate to a good cause.
I have taken a MagneCharger apart before, and it would be fairly easy to
replace an LPI w/ SPI in these chargers.
Does anyone know where we can find some SPI paddles w/ integrated cord?
Thanks!

Hello All:
While I was cruising down the road, I was wondering about my current draw
at different speeds. And I was asking myself, if *my* current draw is
comparable to other people with comparable configurations. Or, if due to
cables, contacts, brushes etc. I need more current.
So, I'd like to ask you what your car or truck pulls. As an example, I
need about 140 A of my 144V pack (which, at that time shows about 135 V
when fully charged) to maintain 55mph (S-10 with 22 T-125s).
Is that too much? About right?
Thanks,
mm./

One side note on trailers. Very few trailers have shock absorbers,
but if you ever fit them to a trailer you will see why all
should. They vastly increase the stability and help make the whole
rig much more controllable. While they almost certainly wouldn't
have prevented this disaster, they might have reduced the damage by
allowing the rig to be brought under control more quickly.
Just food for thought.

Hey Mike
Haven't seen any hits but Waylands on this thread so I
wanted to pop on in to say I care man!
As to your RPM question I'm thinking that you better
plan for a 5Kish high end limit. George Hampstra is
very helpful I'd get his input as to where they'd like
to set the Warp9's safe RPM limit. Being you'll be
pumping on them hard the comm's will be a little
warmer than your daily motor 8^) So factor that in as
you push these pups. BTW I'd love for any feedback on
people who run 9" motors and what RPMs they have
pushed to.
Now if you ain't just waving more yarn in my face and
you send them on over for a pit stop for some light
pimping, the comms will be left OEM so lets stay with
OEM specs toward them.
Had a little idea maybe if you brought some friends
with no luggage down for a Portland EVent you could
fly em back for free 8^o We flew hundreds of lbs of
fish home last year 8^) The Halibut was sooo good.
My sis is down BTW so I'll get to hear how life been
this winter, says its light till 9 already up there.
Anyway unlike Wayland who you (made sure you) met up
and showed off your wares to I remain so far shuned
8^( If you would like to meet up on this I would be
most honored and agreeable. And I'm saying it in
public so we can all go back and read it next year
when you start spouting off borax stories about me 8^)
As for the Pinto at least the gas tanks out and your
motto doesn't have to be "I blow up, so you don't have
to" for a little EV plasmaboy tongue and cheek 8^)
You just keep me posted Alaska Man. I'd love to help
ya turn Donkey into a Noble Stead! (thats from
Shrek)(for those without kids)
Had fun Mike, you go boy! That'll stretch the racers
from one end of the states to the other. Come to
think of it, thats sucks! We all just need to pick a
spot where we all could move and be an EV drive away.
Then again we do more damage seperated 8^)
BTW FWIW last year my sister hauled me all over that
state as we tried to squeeze all we could from the
trip. Having got to know you I think I missed an
oppertunity to have visited a "must see" if EVer in
Alaska attraction!
Had fun

I've been pacing feverishly all winter waiting for warmer weather so I can
resume working on my
car. The goal is to get it registered so I can make it to PODC. But I've also
been looking a the
NEDRA rules to see what else I need to do to the car to make it track worthy.
I'm a little
concerned about the rules for my battery boxes and don't know how to rate them.
I have a
wood/fiberglass boxes that are attached to a metal from that is attatched to
the frame of the car.
I have fiberglass lids for the boxes that will be bolted in place and finally a
plywood "floor"
over the battery boxes. How do I figure out if this meets the standards? If I
don't have my cells
strapped to a metal frame, am I out of luck? I have 144 BB600s back there, how
am I supposed to
run straps across all of them? I hope this isn't a non-starter.
Looking forward to Hagerstown,
Dave Cover

I'll second this. Its really easy to do when trailering an EV, since
most EVs have a majority of batteries in the rear. This means the EV's
center of gravity is farther to the rear than a standard vehicle. To
get that center of gravity forward of the trailer wheels you either have
to pull way far forward on the trailer, or load the EV backwards.
I went against my gut feeling one time loading the MR2 behind a friends
Highlander.
It went out of control on the the local bypass, and he ended up taking
it off road and halfway up an embankment.
Tow dollies are another option, they are lighter and more stable behind
small vehicles.

I must ask, from where does this confidence come? Have you a degree in
mechanical engineering with years of experience in engine design?
What do you mean by "within bounds"? Meeting federal tier 1 specs? ULEV?
SULEV? Just squeaking by your state's emission check?
Using an engine like that, you're unlikely to come even within spitting
distance of a 15 year old, indifferently maintained ICEV.
I'm not saying "don't build it." It could be a very interesting exercise.
But don't delude yourself about its greenness. And for goodness sake don't
mislead others about its greenness. Showing something what you describe at
an Earth Day observance would be hypocritical, IMO.

Just the standard shocks at the wheel. Once you get all that weight
bouncing up and down it can really be hard to get back under
control. I built a two-car carrier with tandem axles with shocks and
it was absolutely stable to tow. I have also used them on two
utility trailers and it really made them behave well. I just
borrowed a standard trailer without shocks from a friend and the
absence was definitely noticeable.

Allright then, how about a 3.07 gear for 110mph @ 5158rpm w/ 22" tires?
I'm wondering how much more torque those two 9's will get over the two 8's?
(Hey Goerge, any chance of getting a set of curves at rated voltage to rated
RPM?)
I'm wondering what Matts gearing was like in around 4th gear?
I know Steve Clunn had no problem launching is Mitsu direct drive from the 11",
but he appeared to be running an open diff. I'll
be coming in a little lighter than those two so hopefully launches would still
be OK EVen with a 3.07. I dunno though. I wonder
what Rod was gearing the Maniac Mazda at?

Or I may have my dad from Fossil come get them from you and drive them to
Portland and just put them airfreight on Alsaka

Now borax! there's an idea. Wonder if it'd work better on my teeth than the

Yeah no doubt. That poor old car will finally get some respect with its biggest

I don't know, racing the ICE when you know you're going to win won't push you

Hey I've been here 10 years and I still haven't seen EVerything in Alaska yet.
A lot, but there's still so much. Hey if you have

Some of us do care. I thought it was a great story and wish I'd been there
to see it. I've never seen EV drag racing before. I hope to attend the DC
EV racing in Hagerstown, MD in June.
I just didn't have anything constructive to add so I made no comment.

Hi Mike, Thanks for responding. I have noticed over a period of time that
there does not seem to be a lot of responses to items of this nature. I do
not really know if people on the List do not really care about pressing the
envelope of EV performance or not. I am not sure if it is apathy or
something else. John is by far the best orator on these adventures and this
subject and yet to see so little response seems to me to indicate little
interest. This actually may be the case now days. Several years back there
seemed to be quite a bit more interest in pushing the envelope of EV
development but hey, times change and we are now living in a world of
apathy. Note: purely my own opinions from my own observations. I am sure it
is not everywhere. I just happen to live in the US. It is not my fault where
I was born. For people born elsewhere please speak up on your opinions of EV
performance.

Hi Michaela,
It is the power that counts, current varies with the voltage level of the
batteries to give a certain power which overcomes the friction.
Luckily you specified both, so here we go:
135V x 140A = 18,900W, say 19kW.
My truck is also a 1994 S10 with a 312V pack, to maintain 55 mph at level
road it uses about 50A.
50A x 320V = 16kW
Now this truck uses an AC system and higher voltage, which could give a
slightly higher efficiency.
I also run my tires at 50 PSI and checked that the toe-in is about zero
(minimal friction).
It appears that your power consumption is very close to that of my truck,
even though there are large differences in the used system, so it appears
that it is comparable.
BTW, I documented the power in the EV Album. There may be others who did
this as well?

Subject: Current Draw For Different Cars
Hello All:
While I was cruising down the road, I was wondering about my current draw at
different speeds. And I was asking myself, if *my* current draw is
comparable to other people with comparable configurations. Or, if due to
cables, contacts, brushes etc. I need more current.
So, I'd like to ask you what your car or truck pulls. As an example, I need
about 140 A of my 144V pack (which, at that time shows about 135 V when
fully charged) to maintain 55mph (S-10 with 22 T-125s).
Is that too much? About right?
Thanks,
mm./

60% because when you hit a bump the weight will shift slightly.
One other consideration... don't exceed the rating of your hitch and check
the mounting. Trucks will often have frame mounted hitches, spaced fairly
well across the frame, while a car will often mount to the unibody. In these
cases, it's sometimes found that the hitch is strong enough, but not mounted
into enough "meat" on the car body.

Hi Michaela,
Looking at your EValbum page
http://www.austinev.org/evalbum/693.html
I believe you meant to POST that you have 24 US125s in your
pack.
Your surface voltage and current draw does not seem right for
a Blazer conversion with off-the-shelf DC design components.
I have an 1985 2 door S-10 Blazer EV conversion with a 132VDC
(22 US125) pack, an Auburn C600 controller, driving a 4 speed
manual (Chevy used an Isuzu tranny back then) and non-low-rolling-
resistant tires http://www.austinev.org/evalbum/12
My pack is about two years old, but still in good shape (it is
not using excessive amount of water). My pack's finishing voltage
at 80F is (2.583VDC * 66 = ~170.5VDC) about 171VDC. On a full
charge the pack's surface voltage (6.4VDC * 22 = 140.8VDC) is
141VDC.
On a full charge & driving on a flat highway (Hwy 101 between
Palo Alto and Mt. View) at a steady 55mph the pack draw is
under 100 amps with a surface voltage of 125VDC.
I suggest you check your Zivan NG3 charger that it is charging
correctly (@80F: 2.583 VDC * 72 = ~186 VDC). If your pack is
not being fully charged you will draw more current, and you
will age your pack prematurely.
My conversion weight in at 5000lbs (without me in it). I have
the tires pumped to 42 (front) 44 & (rear) psi.
How old is your 144VDC pack? If you have a mix of old and new
batteries, a weak battery could be acting as a resistor to drag
you down (see Lee's POSTs on this in the archives).
Good Luck :-)

Hi Bruce,
Good to see that you have your EV repainted, even though you lost the
telltale PV panels on the hood.
Is it completely fixed again or is there still work to be done?
(Usually re-painting is the last step on the exterior.)

That's why I prefer flat-tow or dolly-tow: most of the weight
and steering/follow-capability is intact when using either a
dolly or flat-tow, as the towed vehicle has all its wheels
on the ground and shocks, springs, etc hold it to the road
as it normally does, only the way it is accelerated has
changed.
As long as you are not towing a 4WD, there is no reason to
use a trailer, unless you already have a trailer but no
dolly or tow hook, OR the towed vehicle can't sit on its own
wheels, or it is better not to tow it at Freeway speeds
(for example a golf cart).
Yes, I know - mounting a tow hookup on the towed vehicle
could mean some mods: I have now two small holes in my EV's
front bumper. But I can tow it anywhere I want by only
borrowing someone's vehicle with hitch...
YMMV,

Jeff,
I have an idea how you feel, because I have experienced this issue from up
close.
In essence, you have "stinkers".
Batteries that can be charged, that will put out the amount of current and
stay up in voltage when freshly charged for a while, but have cells with
much reduced capacity from earlier reversals. Once you take out some charge,
one after another cell goes flat and it will show a progressive drop from 12
to 10 to 8V (depending on whether one or two cells go dead). Not only do
they go dead, but they can become high resistance and charge in reverse
direction.
You will notice that when you feel the batteries as soon as you get home,
you will be able to tell which cells are bad from the temp rise.
I 'created' stinkers by discharging them too deeply while they were getting
unbalanced.
That is my reason to be building a battery balancer now.
I kept the bad batteries (replacement under warranty did not require to
return them) and since I hear a story about keeping them on float charge for
many months may cure the bad cells, I am trying that process now by
having all bad batteries parallel on a 13.7V power supply. They draw an
approx 10mA each after the initial days of slowly tapering down. We'll see
what they do in the future, I'll report on the results soon as I found two
other stinkers in my pack, which I need to replace as soon as I can, and
I'll load-test the previously bad batteries to see what their capacity
currently is.
You may want to contact the battery manufacturer and ask exactly how the
process is - how long will you be without batteries, will they send you
replacements when they pick up the bad ones, with pro-rate payment by you?
Success,

Subject: Battery Dilemma
Delimma, Do I send in all 20 batteries to exide for analysis or live with
the reduced capacity and inevitable demise.
backstory:
I have reduced capacity on my exide orbital pack and the distributer
replaced under warranty the 4 that failed obviously.
Since then I have been commutting to work and it actually makes the 12 or
14 miles(6 or 7 oneway). But at around 8miles (half way home) a few began
to drop below 10.5 ( te reg led comes on) during acceleration and I have to
go lighter and lighter on the acceleration to keep the pack voltage above
240 (24 batteries).
When I wait an hour and measure voltage it indicates at least 30% capacity
remains but if I use a 250 A load 1/2 the batteries show a solid 10.3V and
the other half drop to 6V and I abort the test. Fully charged, they all can
belch out 15sec of 250 without dropping below 11.
(limit of my tester)
I didn't want to replace 1/2 the pack so I asked what the distributer could
do on pro-rate perhaps, This is month 17 of the 18month free replacement
warranty.
The factory said to send them on for analysis. Some of this will be
destructive analysis, I am sure.
Any one delt with this before? If I send them in I am without my EV for
weeks, and am assured I will be buying a new pack, either pro-rated or not,
or 1/2 replaced and half purchased. Anyones guess.
