The bmsbattery 24V LiFePO4 doesn't work - probably too little current (Amps). I've had this problem with LiFePO4 before - I've built LiFePO4 packs before, but they had very little Coloumbs, so they were pretty much useless. I have a lot of LiFePO4 cells laying around. Maybe I'll make a backup power supply for computers out of them.
I ordered the bmsbattery 36V 10AH Li-Po battery, like you, Stig. It works fine with the 24V controller, except the controller gets warm. I think it is possible to burn it out with heavy usage, so I might want to look into getting another controller.
The speed with 36V is nice, I estimate around 20mph - there is no real need to pedal anymore, except to get some load off the motor when going uphill.
The speed with 24V got clocked at 14mph by one of those school-zone speed radars. There is a frequent need to pedal.
24V is plenty when off-roading and fine for riding on side-walks. 36V is fine and 36V*10AH = 360WH, so more range overall, but 36V might be a little too fast to be safe on side-walks. Overvolting might kill the controller sooner also. As it is now, it is good to have both options. The batteries are light, so I can ride with both available.
