Hi,
I've been using a 36V motor that draws ~13A current at peak. I initally used a set of three lead-acid (12V 12A) batteries in series. They had sufficient power to easily pull not only my weight but also payload of 10kg more. They gave me a speed of 35km/h at full speed. I have now replaced them with a set of Li-ion batteries (10 x 12.8A + 10x 12.8A = ~26A) however, I am worse off than the lead-acid batteries. They can't even provide enough power with the same motor to carry my weight at 15km/h. Without the load (i.e. running the bike without riding on it), battery current indicator stay full at full throttle but when I put weight on it, battery instantly drops to lowest mark on the indicator.
Can anybody tell what is going on and how can I get the power from the batteries?
Thanks,
