Turnigy LiFEPO4 packs

[suicideneil]

Pre-warm them in your pockets/indoors to around 100*F, then dash outside to use them; the longer you wait, the more they will cool down- dont store them in a gargage or shed either, store them in your nice warm bedroom.

Anyway, I would use 2 of those packs in series, say 6s2p to replace a 5s lipo, or 4s2p to replace a 3s lipo, or 5s2p (3s + 2s packs) to replace a 4s lipo.

But... $120 vs $25 (2s2p 4500packs, direct comparison)= MA are toast- spread the word brothers!
