There is a difference between cosmetic anodizing* such as on the
Alltrax and hard anodizing. Primarily having to do with the thickness
of the coating and certain chemical treatments. Even hard anodizing
can be attacked by KOH but it is much more resistant than plain
aluminum or cosmetically anodized aluminum.
* cosmetic anodizing is a thin anodized coating that primarily holds
the color dye.

I'm breaking in my ADC motor (which is already attached to the
transmission), by running 12V through it to wear in the brushes. I've
attached a 500W power supply to the car's original 12V SLI battery, then
hooked the battery to the motor.
At this voltage, though, the motor is drawing 50A - 70A, which I think is
making the power supply cut out, so the battery runs down very quickly.
What can I do to limit the current to something under 40A, preferably 25A or
so? This is an 8-inch ADC motor.
Thanks.

Vinegar in the electrolyte will definitely kill it. I shouldn't think
it would hurt the outside of the batteries. I can imagine the problem
of keeping the batting wet, though. Acetic acid is somewhat volatile,
which is why you can smell it :-) You might consider one of the solid
acids. Dissolve one of the acids in water, soak the batt and let it
dry. Cream of Tartar is one. Sodium Thiosulfate (photographic fixer)
is another that comes to mind.

Powder coating is tough, durable, fairly chemically resistant, and
pinhole-free. It has no solvent so there's no pores created from when
the solvent left the wet paint. Cheap powder coating systems are
readily available now, you just need an oven. Or some people actually
use big propane radiant heaters to bake parts in a less controlled
manner. Since aesthetic perfection is not a priority for battery boxes,
there is somewhat more leeway.

Hm. I already applied a base coat of por to the box; is it still
possible to anodize?
My first Alltrax controller was supposedly anodized (blue) and did not
hold up at all when the Nicads spewed on it. It melted the color
right off. I don't know anything about anodizing, but I did see this
with my own eyes...

Here's what I did with mine. I had a dumb old shop battery charge. The big ones
which will charge forever and blow up batteries. I hooked it to my motor and
set it to it's 50 amp setting. It spun a bit slower than when it was hooked to
a battery, but sufficed for brush break in just fine. Of course you may or may
not have one of these laying around. A 15 amp cheapy battery charger just won't
quite do it, been there tried that.

Hello Chris,
The wire type depends if you are running it bare, insulated, in a enclose
container or suspended in air.
If insulated, then there are temperature ratings from 140 F to 194 F.
A No. 2 AWG copper stranded wire is only good for 88 amps at 140 F. that is
enclosed with three other conductors.
A No. 250 MCM wire is good for 205 amps at 140 F. that is also enclosed.
A No. 2 AWG at 195 F. rating is good only to 119 amperes enclosed.
A No. 3/0 Awg at 195 F. is good for 214 amperes.
Now running as a single wire in air which would be the battery links between
the battery post, then:
The 2 AWG at 195 F. is good for 138 amps.
The 2/0 AWG at 195 F. is good for 215 amps.
Normally most EV'ers that used there EV for standard mode, not racing, will
use 2/0 AWG battery links and may run 2/0 feeders to the controller or 4/0
if your cable runs are from the rear to the front and are enclose, is good
for 253 amps at 194 F.
You can also add ventilation to decrease the temperature of the load bearing
components. The following formula for ventilation:
(volts)(amperes)
Ventilation = ----------------- = Cubic Feet Per Min (CFM)
48.7
Roland
What would the amps be for an enclosed, 4 guage, very fine stranded pure
copper wire with a 221°F rating (OD 0.4 in)?

I just had some parts quoted for anodizing and there were 2 different
"types"
The shop i went to called it flash anodizing and hard anodizing but
really it was the length of time and strength of solution
The flash gave really bright colors as it more a thin layer on the
surface for asthetics and scratches easy. It is really a thin layer of
clear anodize and a dip/wipe of color. They get interesting graidents
this way also.
The hard was a matte finish, with less color choices because , while the
same colors are used, the color is taken into the parent aluminum deeply
and the acid colors the alum a yellow tint, so it effects the color.
The color is in the main tank and dedicates the batch to that col0r so
it costs more and has a longer lead time. The dark colors like black
tend to look best in this hard anodize, although I saw a deep moroone
color I liked. For the part I was having quoted, the difference was $15
flash and $60 hard.
The hard anodize makes the surface harder than steel or so they say, And
I will have to attest to that haveing to try and add tapped holes that
were forgotten or not plugged before treatment.
This was "anotech" and they have a few california shops I think, but
clovis is the main facility. google "ATMF"

Hi Shawn
Thanks. I'm going to put you down for the O.J. and the Metro.
Let us know when you do get the word on the MG big red. Would be great
for advertising.
As was explained quite some time ago on the EVDL, NetGain no longer has
the "Bad Amplitude" dragster. Two years age, three of us partners split
from NetGain and as our proceeds we took all the racing stuff. Since
then, most everything has been changed. Different motor, trans, tires,
battery, controller, charger and battery management system, paint,
chassis mods, etc. We are now known as "High Voltage Racing". The
dragster has been christened "Aggravated Battery". And yes we will be at
our event.
Our group consists of Kevin Zak, Karl Klein and myself, John Emde.
See ya in May.

It was. There was a temperature controlled fan on the box. Unfortunately,
the battery that had the temperature sensor mounted to it was the one that
split, so the temperature sensor was just monitoring a chunk of plastic...
As a result, the fan wasn't on. The box had plenty of vent holes though
so the explosion just made a big noise..

John,
The Electropolitan is a daily driver and ready to roll. Not exactly a

Mg red car is still a longshot but it sure would be fun if we can get
it there.
I can't wait to see "Aggravated Battery"
OJ-2 is in pcs since I replaced the Zilla with the old OJ contactors.
ALOT of wiring to do.
IF CE4 will commit to coming I'll make sure I get OJ-2 back together
and put up $1000 for the quickest single 1/4 mile ev dragster run at
the event.

I need to add one stipulation to the potential $1000 dragster challenge.
It would only be open to NEDRA members.
There is plenty of time for those who aren't members to sign up before

EVent due to a low turnout. So, this plea goes out to any and all
who
are thinking about showing up to please register at our web sight
www.fveaa.org or contact me John Emde at [EMAIL PROTECTED]
by
Monday 3/27/06 at the latest. Also, if you know any NEDRA
"record"
holder, have them contact me directly as we have a sweet deal for
them.
Record holders that have committed so far are John Wayland, Bill
Dube',
Jack Knofp, Darin Gilbert, and Brigham Young Univ. This is your
chance
to rub elbows and fenders with the best in their class. HVR's
"Aggravated
Battery" dragster will also be there.
There is NO entry fee for any EV. Prizes include trophies and
cash
awards.
The event is being organized by High Voltage Racing, the Fox
Valley
Electric Auto Association (FVEAA) and is sanctioned by the
National
Electric Drag Racing Association (NEDRA).
All pure electric vehicles (2, 3, and 4 or more wheels) are invited
to
participate, either as a static display or drag race in the NEDRA
event.
All alternative fuel vehicles (cng, hydrogen, propane, bio diesel,
veggie
oil, steam, etc.) and hybrids of all makes and fuels are also
welcome to participate as part of the Alternative Fuel Vehicle
(AVF)
Expo
which is also being held at the Route 66 Raceway.
This is in conjunction with the Joliet Township High School's
(JTHS)
Alternative Fuel Vehicle (AVF) Expo.
The event will also be held in conjunction with the 5th EVer EAA
All-Chapters Conference that same weekend from May 12 to 14th
which
will
also be hosted by the FVEAA. The 5th EVer is a gathering of EAA
Chapters
to conference about opportunities to promote and develop EVs.
Check the web sight for more details as they become available.

Wow John, the last set they gave you was less than a year ago! Is it
typical for racers to replace their batteries annually or did yours die
prematurely?
If your old ones have any life in them I know an old jalopy with Genesises
they'd look good in...

As a regular every week drag racer I now have over 360 runs and 13 months on
the 16ah pack of Hawkers.(DONT forget I race when ambent temps. are over
110f)After discharging the entire pack to 10.5v 2 weeks ago I found that it
took
9.5 minutes longer to discharge the pack then when they were almost brand
new(15
runs)With the shallow cycles they see from the CE I would sure like to get a
thousand runs.By the way I have PAID for all my hawker batteries.

John,
I need to add one stipulation to the potential $1000 dragster challenge.
It would only be open to NEDRA members.
There is plenty of time for those who aren't members to sign up before
the race.

You can use US gauge 4. Most of the time it won't even get warm.

The truck will cruise at 60, max sustained draw of around 140, peak draw
of about 200amps.

Now you really have to come to the race. Non of us easterners have ever
seen an ev go under 10 sec in person. It would be a great way to show
that you are an ambassador of the sport. As an added bonus I believe
High Voltage Nationals will offer substantial "tow money" to get you
there. What's there to lose??????????

That is one that you have to answer for yourself. The primary effect
of undersized wire is limiting the available current and thus
acceleration. Secondary effects include heating and range loss.
*nod* Ok, I can deal with that. The Dolphin controller's IGBTs max out
at something like 250a, so the Dolphin itself is current limited to 200a
and the final crash fuse is (I believe) a 250a monster. So 200 is fine.
What is acceptable is something only you can decide. Personally, I
want the most acceleration I can get so I use what is probably a bit
oversized wire. It only costs a little more so it's no big deal.
The big reason to go with the 4 gauge is that my little supply of
perfectly shaped nickel plated lugs will accept up to 4 gauge wire. If I
go 2, I need to go back to the nickel plating man.
If your question is, "will 4 gauge wire melt down and burn my car
down?", the answer is no. It'll get a little warm at 200 amps but
unless the wire is run through insulation (fiberglass sound damping
batts, for example.), it won't be enough to matter.
That's the biggie: I really hate it when I burn things down. The run
from controller to car is 2 gauge from the contactors, so I can live
with the voltage drop on the battery to disconnect switch.
Thank you
Chris

update on my original post...
in the event there are any other newbies like myself lurking around and
looking for info on the GE EV-1 controller, a long-time EVDL member
contacted me off-list with some generously offered and very welcome
advice, plus a pointer to an inexpensive EV-1 technical manual available
through Flight Systems Industrial Products:
description here:
http://www.fsip.biz/techmanuals.htm
in their catalog here:
http://tinyurl.com/sxmms
since i posted the original message in this thread, i also obtained 2
old service manuals from the company that sold me the surplus lift
truck. these manuals have sections on the controller (and other panel
components) which i'd be willing to share if anyone needs info.
and in the event nobody else is currently looking for information on how
to set up a 25 year-old motor controller ... :-) ... at least this
message goes into the archive for posterity where it may be useful for
someone doing a search in the future. (the archive is a great resource
- i've spent many hours on the learning curve in there.)

A No. 4 AWG multi strand copper wire with a insulation that is rated at 105
C(221 F) that may be enclosed in a wireway with two other cables, or three
conductors that has not over 60 percent fill and each wire is space so there
is not more than 24 inches of surface contact between the conductors in a
ambient temperature of 20 C(68 F) shall be rated at 140 amps.
The maximum length in this type of spacing is 80 feet.
As a single conductor in open air, then the maximum is about 180 amps.
If there are more than three conductors in a raceway, than you must de-rated
the ampere by 20 percent.

Ok. This will basically be open-air, as it will be in the very large and
ventilated battery box with single-point runs between 3 points on the
pack and the disconnect. The runs through conduit are all 2 gauge or
better factory wiring.
Thanks! This is all actually coming together :-)

Aluminum is corroded away by KOH electrolyte. The longer the exposure,
the greater the damage. So aluminum might be ok if you rarely or never
get KOH on it; but bad news if it routinely gets misted (as it would
with flooded nicads).
However, the commercial battery boxes I see for nicads never use
aluminum. They are always stainless steel or nickel (which don't corrode
in KOH). Is there any special reason why you don't use one of them?

Thanks very much!
Thinking of ordering this:
