I have two Pedego Interceptor E-Bikes with 48 volt batteries and one of the batteries has died and the other is perfect. Both are rode equally. The bike is out of warranty and I wanted to know if there is a DIY to fix the issue before shelling out hundreds of dollars for a new battery. The charger is fine. I use the same charger for both batteries. I recently installed the battery and hooked the charging cable to it and bike worked everything powered on. Unfortunately I can’t ride like that. Any assistance would be greatly appreciated.
