Does anyone have any experience with this company ?

BatterySpace.com/ AA Portable Power Corp.
2700 Rydin Road, Unit C
Richmond, CA 94804

Phone: 510-525-2328 Fax: 510-439-2808

I'm having trouble with their "policies" ... :)

Sam,

A little pricey now but I like the Optima Red Top and the Blue Top from
Costco. Being a sealed AGM battery they do not corrode the terminals,
and take a large quick charge if you do have an occasional problem. If
you get a bad one, or one that goes bad after some time, I just clean it
really good so it looks like new, and march right back to Costco. In
use in an ICE vehicle, they last so long that you have to remember to
swap them out when you sell the vehicle if you want to keep them.

I would think the Exide Orbital is in the same ball park, expensive, but
no acid leaks to corrode things.

Good luck,

Alan Brinkman

[EVDL] Battery

Anyone know anything about these?
http://www.b2i.cc/Document/546/113226.pdf

Seems too good to be true, 12,000 cycles at 2C and 18kW from a 24V battery
the size of a car starter battery weighing 25 kG. 500A max current.

Re: [EVDL] Battery

I didn't think these were available, or that the company was still in
business. The page has a 2010 date on it. I wonder what the price is?

Re: [EVDL] Battery

Well, I emailed them asking about the application kit that they sell. We'll
see if they respond and how many millions they want for it. It would be
great to be able to test some of their claims.

Re: [EVDL] Battery

I use their cells, they are fantastic from a power, safety and
longevity standpoint. The energy density is somewhat worse than
LifePo4 but still beats NiMH. I was never impressed with the way they
packaged the cells into modules, this appears to be a new design but
it still looks rather amateurish.

Re: [EVDL] Battery

I have no idea what these modules cost, or what regulation they need.
The cells themselves are like any other lithium chemistry, only lower
voltage, they need a BMS.

Re: [EVDL] Battery

The specs on those batteries can't possibly be for real.
They would be the most popular battery in the world if they were.

Well, they dont have very good Specific Power or Power Density
(relative to TS) at 0.045kWh/kg and 88kWh/kg respectively (0.09 & 137)
nearly half in fact. So they arn't exactly 'the Holy Grail' of EV
bateries. Their main claim to fame is their cycle life although why
they are a lot happier doing 2C charges and discharges rather than 1
is a mystery.

Re: [EVDL] Battery

Your numbers and/or units doesn't make much sense, how did you come up
with those numbers?

As for the cycle life difference between 1C and 2C, look at the
temperature. I agree that it is a very confusing way to present that
data.

Re: [EVDL] Battery

Oops.. Power Density units should be in kWh/m^3 = Energy Capacity in
kWh divided by volume in m^3. Specific Power is Energy Capacity in
kWh divided by weight in kg.

Re: [EVDL] Battery

You are mixing power units up with energy units. Power is kW where as
energy is kWh. Therefore Power Density is kW/m^3 and Energy Density is
kWh/m^3. Specific Power is kW/kg and Specific Energy is kWh/kg.

Re: [EVDL] Battery

WOW, all that alphabet soup was beginning to make me sleepy. Thanks Martin
for the clear / corrected summation.:

"Power is kW where as energy is kWh. Therefore:
Power Density is kW/m^3 and Energy Density is kWh/m^3.
Specific Power is kW/kg and Specific Energy is kWh/kg."
