Lipo quessies

[Nick]

So how would I charge LiFePO4 at to do them in around 35minutes? Do you think they are good cells?

What determins how fast you can charge them, with Nimhs they are all the same, with Lipos it seems that the batteries determine it?

...and I see 6s packs, which is around 19.2v, do I only need 1 pack? So I only have on pack on my truck instead of 2 nimh packs of 8 cells or how ever many? Do I go for 2x 3s Lipo, or just 1x 6s Lipo. :S
