I have an e-bike using a 36 volt/9 amp battery pack.I want to up grade the compacity to 48 volt/9 amp battery pack. Can I use the same smart charger for the upgrade?
Usually there isn't reverse power protection with chargers because putting a diode between the charger and the batteries is the same as there not being a connection. That means if you put larger batteries in the charger it is like putting larger batteries in a portable radio or boom box. The charger might be able to handle it for awhile but I think the 12 volt difference would be too much.
