a123 6.6v questions

[ClodMaxx]

i gotcha. that's why i'm planning to gear up to a 20t pinion (i was planning to use about a 17t on the 14 ni-mh cells) to get around the same speed. but if i go with 5s instead of 4s, i should be able to gear back down... or is my thinking flawed?

edit: going up to 5s a123 cells will require a new controller. i may 'experiment' with the MM, however. since i have two 2s2p packs, i'll have to make a 3s2p pack from the dewalt packs...darnit. but...if i bought a dewalt pack and built a 3s2p, i could use the remaining cells to make a 4s1p pack for my crawler. ding ding! we have a winner!
