Looking for 72 volt LI-ION/18650 charger

Post by rumme » Oct 28, 2017 4:02 pm

I currently have a 3 amp charger but wanted a fast charger . Can be new or used, as long as it works properly. Let me know your asking price and the charge rate in amp hours. Ty

Charge rates are in amps, not amp hours.

Amp hours are only a capacity measurement of a battery (or a measurement of power usage).


Also note that before you get a new charger you need to determine the max safe charge rate of your cells/pack, and be sure the new charger will not exceed that rate. Cell damage can occur, either slowly over time or quickly from overheating, depending on how far past the current limit you are charging it.

If you have a BMS on the pack, you also have to not exceed the BMS's max charge rate, or you can damage the BMS's input FETs.
