them have gone to my inbox. I also don't see a bounce score in my options,

If living in this modern media-saturated world teaches us anything, it's
that advertising is full of BS (Baloney Sandwich filling :-). A given
device may or may not work -- but the advertising for it is *totally
unreliable* as a source of information!
These battery desulfators are particularly bad in this regard. Their
descriptions of how they work are junk science. They give testimonials
from unknown or anonymous users instead of verifiable test data.
The device may be a good charger, or a bad one -- but you sure can't
tell from their advertising!

Frankly, there is no way to know except to test it. And to do a proper
test, you need to measure what it ACTUALLY does.
I've done this a number of times on various battery chargers and other
devices that claim to desulfate or rejuvenate a battery. Some of them
actually work -- basically, because they are a perfectly normal battery
charger, recharging a perfectly normal battery. The "desulfation" claims
are just marketing nonsense to get you to buy the product. All they
actually do is what is more properly called "equalization" -- a long
slow charge that provides enough total amphours to fully recharge all
the cells, without overdoing it to the point where it causes further damage.
The worst of the devices do nothing at all. But, the instructions for
using them tell you to do a normal charge and discharge cycle to "test"
the rejuvenated battery. It is this normal charge/discharge cycle that
actually does the work!

Tim, I agree, it's not like he got drunk with his buddy and decided to
trim his hedge with the riding lawnmower (cut their fingers off..)
He was riding a well-engineered machine and did as it was designed to do
- accelerate very rapidly! I'm not usually the guy to say so, but it
sounds like it being electric has got a lot of people talking about it more.

Go here :
http://lists.sjsu.edu/mailman/options/ev
Enter the mail address you use for the EVDL. You'll need your password to
log in (it was in the welcome message you received when you subscribed - you
DID save that message, no? ;-). If you don't have your password, never
fear; just scroll to the bottom and click Remind. The page will tell you
that your password has been mailed to you.
If you don't have web access at that moment, instead of using the webpage
above, you can email a message with the subject
password
to the address
[EMAIL PROTECTED]
In the message body, type
end
The message must be sent from the same mail account with which you're
(supposedly) subscribed to the EVDL.
Whichever method you use, check your email for your password. It should
arrive within a minute or two.
If you DON'T receive your password, the most likely reason is that you're
NOT subscribed. (Mailman apparently doesn't check whether your address is
subscribed until AFTER it's already cheerfully told you it's mailed you your
password.) The old list manager, Listproc, returned a "You are not
subscribed" message when a nonsubscriber queried it. But Mailman is
different; if you're not subscribed and you request your password, it just
ignores you.
If you DO receive your password, use it to log in and check your
subscription settings. The top of the page will tell you what your bounce
score is (if any) and warn you if you've been suspended. Further down the
page you'll find the option to enable or disable mail delivery. It's the
first item under "Your EV Subscription Options." That's where you reset
your account if it's been disabled because of bounces.

Sometime ago, I bought a Schumacher Smart charger Model WM-1000A to be use
as a charger for regular automotive lead-acid, AGM, gel cells, deep cycle,
and use as a maintainer which has digital read outs. I use one on board to
maintain the on board 12 volt battery. It can be use on 12, 8 or 6 volt
batteries.
I have tap off leads to a chassis board panel receptacle where I can plug in
battery leads to balance charge the 6 volt batteries as required.
I have another out board one I use for the shop. One day I brought out a
high performance engine I had in storage, which the battery from 1973 was
still store with it, but was disconnected and was planning to replace it
with a new one. The battery which is a Sears deep cycle Diehard, still turn
over the engine, but quickly slow down, so I turn off the ignition.
I place one of these smart chargers on this battery, and the digital display
a voltage of about 10.2 volts. Turn the switch to the charge for a deep
cycle and it commence to charge. The voltage readings quickly climb to 13.5
volts and then it increase to 15 volts, it then drops back down to about 14
volts and then goes up to 15.5 volts and repeat this cycle many times, and
then it took the voltage to 18.2 volts and then drop the voltage to 14.5 and
held it there for awhile and repeat that voltage increase to 18.2 volts many
times.
I was alarm at that high voltage, so I went and read the manual more
closely, it states:
The Schumacher SpeedCharger high frequency charger allows for faster
charging by putting more amperage/current into a lead acid battery in a
shorter period of time.
The charger starts with the appropriate rate safety providing as much
current as the battery will take, while automatically monitoring the
charging conditions, avoiding gassing or overheating that may damage the
battery.
Then, it constantly adjusts the rate to effectively complete the charge. If
necessary, the charger will desulphate/recondition the battery plates for
better charge absorption.
So when the voltage cycles from 18.2 volts to 14.5 volts several times and
it waits, this must be the desulphation cycle they are talking about. I do
not know.
But the battery is still cranking over this engine which is very hard
starting at times if everything is not tune right.
My onboard 12 volt deep cycle battery in the EV which is use to run a DC-AC
inverter, four fans and 2 pumps during the start up which could pull up to
100 amps starting. When the main motor reaches about 300 rpm, then the
alternator-inverter kicks in providing the DC and AC current. One day I
found that the on board battery went through this 14.5 to 18.2 volt cycle.
This battery has about 8 years on it.

There's no such thing about bad press.
OK, if it had been a story tied to a vehicle being tragically
underpowered, that could be bad.
Being a story about electricity being too much for him to handle is
typically a good thing, unless you read it as "guy was so dumb he
couldn't even handle a Power Wheels kid's toy without hurting himself".
The circumstances do show enough about just how powerful it was to
probably point to the first case fortunately.

Hi,
Does anyone have crash-test knowledge of the Miles ZX40s NEV (or other +/-
information to share)? It is built from a chinese (I think) glider by a
california company. They add lead-acid batteries, curtis controller, and a
DC motor and limit it to 25mph. In Seattle, the local dealer, MC Electric,
modifies the gear ratio to allow 35mph, per Washington state law.
My biggest concern is safety. I can, perhaps, add some safety features, but
first I would like to know to what level it has been safety tested. I have
found internet sites proclaiming "IC Variant Crash Tested to EU Standards",
whatever that means. Does anyone know?

You can boost a golf cart's top speed to 25mph add all the correct
equipment (lights, horn, etc) and licensed it as an NEV, but it
wouldn't fair well in *any* crash. I don't even know what NEV crash
testing is done, but I doubt they are tested anywhere near that higher
speed of 35mph.

No NEV has anything like the passenger protection of a good sedan. They are
probably more secure in that respect than a motorcycle, but of course they
don't have the maneuverability (and accident avoidance potential) of a
motorcycle.
If collision protection is a concern, I'd say buy a recent compact sedan
that has crash-tested reasonably well, and convert it. Modifying the
structure to add batteries will probably have some effect on its
crashworthiness, but if carefully done it won't be a dramatic effect.

The shorthands probably stand for:
"Industry Canada" variant tested to European Union standards
(unspecified which standard).
If you can find out where the glider comes from, you may be
able to see to which level/standard it was originally tested and
whether it was a (Chinese market) Freeway vehicle, or that it
was designed as NEV from the beginning.
Success with your research!

Hi,
Does anyone have crash-test knowledge of the Miles ZX40s NEV (or other +/-
information to share)? It is built from a chinese (I think) glider by a
california company. They add lead-acid batteries, curtis controller, and a
DC motor and limit it to 25mph. In Seattle, the local dealer, MC Electric,
modifies the gear ratio to allow 35mph, per Washington state law.
My biggest concern is safety. I can, perhaps, add some safety features, but
first I would like to know to what level it has been safety tested. I have
found internet sites proclaiming "IC Variant Crash Tested to EU Standards",
whatever that means. Does anyone know?

I was supposed to post this earlier but obviously I am way late. Dennis's
motor worked well except for the fact that whatever he did to it they had a
hell of a time trying to get it geared tall enough to draw the amps
necessary to extract the full horsepower available from the battery. The
original 671 GMC starter motor we had in it was running a 6 volt armature.
It drew 500 amps at no load. It was modified by key electric here in Port
Townsend. I am not sure if it was Key Electric or Rob that had the roller
bearing installed on the output shaft. Suffice it to say they were able to
crank enough out of the one 12 volt battery for the record. The owner and
driver of the bar stool is Rob Spencer from Idaho. He has been pursuing this
goal for a couple years or so and my congratulations go out to him. For
anyone interested here is an earlier video of me testing it out near our
shop here in Port Townsend. It went way faster on pavement then it did on
the salt due to the poor rolling resistance of salt. If you haven't been
there you would not understand. Here is the video:

I now have all 13 batteries in my Sparrow with Regs (MKIIC).
When I'm charging, as soon as one of the regs "fires", the current drops
to 0, then starts building back up until a reg fires again.
So, once any reg starts triggering, charge current drops to a rather low
value.
Is this normal?

Content-Type: text/plain; charset=ISO-8859-1; format=flowed
I finally got the 2 bad Optima's replaced. So I now have 11 Optimas
with about 3 cycles on them, and 2 brand new ones.
I first charged the 2 new ones with a car charger (set to AGM of
course), and then put them in the pack.
When I turned on my PFC-40, all the regs lit up - except the 2 new
batteries. (This only occured because I forgot to plug the regbus into
the charger. If the regbus is plugged into the charger, you get random
regs triggering and dropping the charge current way down.)
So I then put my bench supplies on the 2 new batteries at 14.45 v (just
below reg trigger level) and let them charge until they had dropped
below 2A.
Now when I tried the whole string with the PFC charger, those 2 lit up
first.
So I then drove 6.7 miles, using 1.33KWH. (198WH/Mile, not too good for
a Sparrow. Better check tires and brakes!)
Hooked up the charger, after a few minutes at 40A, the 2 new batteries
started triggering their regs. So I left it for an hour, and when I
came back most of the other batteries were triggering their regs, but
NOT the 2 new ones.
I tried turning on SW 6 for an equalize cycle, and the charger was
putting out 1.4A at 191V, and NO regs were being triggered. They all
must have been pretty even with each other. I only left it this way for
a few minutes.
Does all this sound normal for breaking in a slightly mixed pack?

I got there around 4, and Dennis got there around 5. What a great looking
EV! Very clean, nothing but EV (except for the genny in the front). I took a
lot of pics and will put them up on the web, give me a day or two. Everybody
who saw it was really impressed.

No. The current is supposed to start dropping gradually (on average) as
the regs blink faster or more regs start blinking. I say 'on average'
because the current doesn't drop smoothly, but rather bounces up and down
between a couple of points that decrease over time.
There is a trimpot behind the charger's face plate for adjusting the analog
cutback. Rich or Joe will need to give you detailed instructions for this.

To: [EMAIL PROTECTED]
Message-ID: <[EMAIL PROTECTED]>
Content-Type: text/plain; charset=US-ASCII; delsp=yes;
format=flowed
Hi Folks,
I'm wondering if anyone in the SF Bay area would be willing to meet
up with a friend of mine who is looking to get some video footage and/
or first hand EV experience for a project that she's agreed to help
me with which is taking place in July 2008 in the UK.
The project is going to take the form of a UK run from John-O-Groats
to Land's End, the most northerly to the most southerly point in
mainland UK. We're not going to be going direct, and the project is
going to involve as many commercially available EVs as possible.
She's going to be visiting me in the UK in November to get some
filming done here as well, but the aim is to produce a promotional
video which we'll use during the event, which we've named "EV-
JogLe" (http://www.ev-jogle.com). The whole aim of the project is to
educate those outside of London about EVs and to give people a chance
to see, experience and drive EVs for the first time at events which
we'll hold throughout the three week run. We could do the distance in
three days, but that'd be pointless as it wouldn't give us quite so
much publicity. Email me for more info anyway!
Amy if a friend of mine from SF and has agreed to take on this
project as film-woman and web tecchie. She's always had to hear me
going on about my positive EV experiences and has visited us in the
past, so has some limited EV exposure. If anyone in the bay area
would be willing to meet with her and let her get some first hand EV
experience I'd be delighted. She'd like to get as up to speed as
possible on what's going on in her local area so that come next year
she's a real EVangelist ;) Perhaps people can email me off list?
She's experienced electric bikes and scooters before, but needs to
experience some larger stuff! All types of EVs would be welcome too! :)
You can either email me at the above address, or at nikki{at}ev-
jogle.com
Thanks!
Nikki.

Would anyone over there in the US be willing to buy some for me, and

G'Day all! I've been lurking for a while, and just had a question
about the a123 M1 cells found in the DeWalt 36V battery packs. This
has almost certainly been covered before, but I can't remember the answer. :)
The a123 website says the M1 cell (found in DeWalt packs) is 3.3V and
2.3AH, yet I've read on web forums and the like that the DeWalt pack
is also 2.3Ah. Surely both can't be correct? I was of the
understanding that, wether connected in Series or Parallel, capacity
was the combined total, ie, 2.3*10=23Ah, for the DeWalt packs, just
like the Voltage is 3.3*10=33V (36V). I understand that Voltage is
different depending on configuration (33/36V for Serial, 3.3V for Parallel).
Cheers.

Connecting batteries in series increases the voltage. Connecting the batteries

On my current eliminator dragster and my smoke screen S10,I bulk charge to
14.1 volts per battery at the track. At home after a day or so I put the
batteries on a balance charge at 14-3.I have gotten as many as 625 cycles drag
racing
my dragster and the hawkers keep putting out as they did at 50 cycles. The
truck now has over 400 hard running miles with its longest run now over 37miles
on 1 string of 26ah hawkers. Resting OCV after being charged (resting 24hrs)is
13.01 to 13.04. Dennis Berube

A starter is just that a starter.The duty cycle is very low on most starters
I have seen.But if you must ask start out with good bearings and brushes ect
from your local starter rebuilder seat in the brushes and keep the carbon dust

both are 'correct'
capacity is not measured in Ah. it's Wh (watthours or powertime)
so the capacity is the voltage times the amphours (Ah).amp hours means
how many amps you can pull in an our. but the power is watt
the cells in the dewalt packs are in series in which the voltage is
added. when they are in parallel the amp power is added. also the Ah
so when you want to know the capacity of a battery setup you multiply
the voltage and the Ah number.

Amp Hours don't increase in series, the amount of watt hours does.
It'd be nice though if amp hours did increase in series.

I want to add a ceramic heater to my Cabriolet for this winter. I'll
probably pay a local Rabbit mechanic to do the under the dash work
since I don't really have the time or inclination for it. Have a few
questions:
1.) I think in NC that a single 1500W heater should be fine, but if
someone in the area disagrees I'd like to hear about it.
2.) I remember reading about folks buying cheap heaters at Lowes or
somewhere and removing the ceramic core from it and using that. I
also see a ceramic heater core at evparts for almost $200. I'm
wondering if there is an advantage is to buying the $200 part other
than avoiding disassembly?
3.) I am wondering about the wiring. Does anyone have a schematic of
how they wired up their heater? In particular I'm wondering how you
wire it up to the pack, how it is isolated, etc.
Thanks alot - De

I have not spent time looking into specific products and their ease of
installation but just in case you didn't know I'd add that compression
heaters (same principle as refridgerator) can give you roughly 3 times
as much heat as you spend energy.
because heating can be a significant part of the power consumption a 3x
gain is worth something.
whether a useful product exists though I don't know

Don't be confusing him now. Usually, capacity = Ah, energy=Wh
