Saw this battery in a drag racing project, it caught my eye because it's installed & not much else is. When I asked why I was told "it's worth $3K because it only weighs 3000grams & has huge cranking ability"...presumably it was bought ahead of time because of the difficulty in purchasing & installed?
It doesn't have any labelling or identifiers. Anyone know anything about these things?
I would use a 4s1p 5000mAh Lipo for a turboed street machine or 4s2p 10,000mAh for a high compression N/A strip weapon (I've started a neighbours deisel car on a 4s1p 5000mAh chinese LiPo) and secure them with bent alloy trays pop-riveted to the tub/spaceframe and held in with velcro straps, Even 2p should weigh under 1200 grams and cont under $500.
I've been thinking of a 4s4p A123 pack for my road car to dump some weight up front, it should be man enough to cope with what the alternator can chuck at it, its not a drag car so I wouldn't want to bother with taking it out and charging it externally to save a kilo and it would still be 10kilos lighter than stock.

I would buy 4 20Ah A123 prismatic cells from A123rc.com, $32 right now, they can dish out 600 - 700 amps no prob, make it a 2p pack and that's 40Ah and ~1200 - 1400 amps.

Thats a pretty serious chassis/cage and big tyre combo. I would be assuming turbo rotary going in the front and quite possibly 8sec or quicker on the quarter mile.
I used to run a drag car in my past and know a little about them. I used to run Odyssey batteries capable of putting out 650 amps under cranking load for about 20sec. Used to start a 460 ci big block ford pretty quick. I really don't know how lipo or life batts would handle high current for 5-10secs at a time cranking a big block over. I certainly don't think the leads would hold up to it. I would also be concerned for the internal batt connections.

At what C rating are they rated? They're very cheap imo, damn!
