Hi Powell,
Thank you so much for the reminder. Been trying to figure out how to deal with this bike to get it going, and then to keep it going!
Saw the info in your threads about Lithium Polymer. Staying away from that to avoid fire / overheating, etc.
Was looking at LiFEPo4 (Lithium Iron Phosphate) because it is supposed maintain the normal temperature, without danger of overheating, unlike Li-Polymer. Also supposed to be a longer lasting battery with over 2000 cycles possible.
What I'm wondering, though, is what the battery specs are, to have enough power, for hills, and a decent ride time, without having to recharge every minute. 36V 30Ah ?? The bike is 1000w. When looking at batteries, I'm noticing some sites suggesting 48V 20Ah for 1000w bike. Your input appreciated, as I have not had this bike on the road yet.

BTW, great help from wrandyr today. The controller and the motor are good. 4 battery hubs, not one that is 100%. Trying to do some swapping tonight. Will keep you posted.
