Electric bike charger & battery voltage question

[newride]

I have a 52V battery and a 52V charger. I worked good for a while but now the battery doesn't charge above 51Volts. So I tried a different charger and the battery charged up to 58.2 volts.

The question is should I buy another charger with a higher voltage to charge the battery?

Thanks!

You have to match the voltage of the charger to the battery. In your case a 52V Li-ion battery should charge up to 58.8V. If you've only been charging to a lower voltage then some of the cells maybe out of balance.
