What is the current best battery options.

[gavztheouch]

I am in the process of transfering parts of my auora alien bike onto my old jump bike.

The battery is totally shot, it will give about 2 miles in assit, but it still puts a smile on my face with the amount of power it has. So im looking at a new battery or try to recondition the old one if thats possible.

I have been looking in to Lipos of hobby king but wondered if anyone else has any suggestions as to the best battery setup for my bike. Also Is it worth increasing the voltage for a bit more speed and tourqe? Will the controller and motor handle it?

Many thanks
Gav

Your present controller is 18 amps with 50v capacitors, so it won't work with a 48v battery, which goes as high as 54.6v. It should be OK with 12S lipos.

Controllers aren't that expensive. If you're going to get a new battery, you could get a new controller with nice LCD at the same time. Maybe even a sine-wave one.

Your motor will do 22mph at 36v with a battery that can give enough current to sustain it. I think that's the ideal speed considering the power of the motor unless you're light. At 48v, it'll do 30mph down-hill, but won't have enough power to sustain it. It should be able to do about 25mph with hard pedalling; however, you might find that it overheats when hill-climbing. It all depends how heavy you are and what type of hills you encounter.
