A123 batteries

[ClodMaxx]

you can build 4s2p, or just 4s to save weight. i bought two 4s2p packs from a123, and bought two 3s1p (wired in parallel, so i can have 5s2p) from someone on ebay. building them seems easy, but i just didn't want to mess with it.

i had 2 Ice chargers as well, but it won't balance the a123's. so i sold one Ice (about to throw the other one on ebay) and bought a123's charger. it's a fast charger, plus it balances the cells.
