I have a 24 volt EV Global bike, 12 amp SLA batteries. The battery pack has a capacitor in it, next to the electrical outlet.
Question: What is the purpose? Does it even out current spikes or give the motor a surge when turned on?
Also, I was planning on putting a second battery pack on the rear rack and wiring them together for 48 volts. I would also use a new motor and controller, probably Crys 400 series.
Question #2: Someone suggested that I run the two capacitors in parallel to get the same resistance. Should I do this? Do I need them at all?
Thanks in advance,
