group buy perhaps?
at $7 a cell its a steal

EDIT: just found that they sell sets of 12, im set!

hahahha why XD.

"what qualifications do you have"
"hold my beer and watch this"

group buy would be a a++ idea though. i cant afford any soon but if i do get a job id definitely buy all 100 for myself

wonder how youd charge so many in parrallel effectively for an EV?

if there was a group buy of some sort i could be interested
that or im half considering something like Poly RC PQ-5000XQ-5S Li-Poly Battery from http://www.rclipos.com/PolyRC30C.htm more expensive then A123 but should last me at least 2 fights probably 3.

Be wary of RC Lipo's for Combat Robot use.

They offer better power-to-weight than A123's, but they are fairly fragile by comparison.

Overdischarging below 3v/cell them will kill them rapidly

regular >80% discharge will reduce their capacity significantly

They have an effective shelf-life of 2-3 years, after that, internal resistance goes up and capacity goes down - even if they arent used much - and thats "since manufacture", not use or purchase, if you unknowingly buy old cells, you could be halfway through that period already)

They can only be charged fairly slowly. Typically 1C, sometimes 2C.. Charge times are usually ~90min since they slow down a lot at the end.

Abusing them with accidental short circuits, sustained heavy loads, or overcharging will often result in a serious fire/explosion (youtube lipo fire)

If you *need* the power/weight, such as an Aircraft/Heli, you put up with their disadvantages, but for harsh-duty applications like ours, it seems to me that A123's improved robustness is worth the lower power/weight ratio.

Waiting for that magic bullet that is "nearly here" seems to have been a non stop thing for the last 30 years in the EV world.

When I'm ready to start on the EV project, I'll just build for whatever is the best solution at the time. likely A123's by the looks of things at the moment. but theres nothing to stop you slotting a better battery pack later if it ever makes it out of vaporware stage.

roughly
that $5.75 a cell ebay price works out at

$13000 buys you ~20Kwh worth of batteries or ~100-150km in a good car
It also nets you ~900Kw worth of output power
the bugatti vaeron is 1000Kw ;->
