100 kW
I just bulk charge my LiPo and I haven't balanced it in several weeks at all. If you mean it's hassle to charge 16S, I presume you mean you want the pack permanently fixed to the bike ? I have mine in a topeak bag because I need to bring it into the house to charge, so it's not an issue. I would love that falcon triangle bag but my frame is only 17" and the triangle is small. Still it might be enough to fit my little pack.
I too believe slower winds high voltage is the way to go, especially smaller wheels because you got the torque in a smaller wheel so you don't need so much current, but you do need lots of volts. I think for the pie you need at least 90 volts for it to be any fun in a 20" wheel.
The ebikes.ca simulator says that to get the same torque with the HT3525 in a 26" rim as a 20" you need to go from a 35 amp controller to 70 amps, that's an astonishing figure, that's half the current needed for the same power. That's 3kw according to the simulator and a speed of about 36 mph.
Now go to a 20" wheel and that torque goes from 120 lbs to 155 but the speed drops to 31 mph.
Switch to 120 volts and the speed goes to 40mph and the torque goes to 180 lbs and the watts to 4kw, that would drain any battery fast!
Go back to 40 amps controller and the watts drop and still 140 lbs torque, enough to throw you off the bike so you would even probably get away with go amps at 120 volts!, haha at that voltage in the U.S you could just plug your battery straight to the mains!
Switch to the HS3540 you still get 110 lbs torque on 40 amp controller and 40 mph use less watts, but it says it will over heat in 24 mins ? The HT will over heat in 14 mins on a 6.5% grade. 120 volts for 30 mph up a 6.5% grade with the HT.
It's kind of hard to know what to do judging by the simulator!
120 volts into the pie would be a lot of continuous watts, so would 80-90 and more current. More testing needed Dave!
Get better soon!

) I was scared as hell thet I would burn my house down, hasn't happened. LiPo has got to be respected an I am aware of that.
