This is a standard charger that will work on all of our 48v shark and bottle packs which all have a 5.5 mm barrel plug. The plug can be swapped out to be used with any 48v 18650 battery pack that needs a charger.
It charges to a maximum voltage of 54.6 then automatically stops charging. Charges to 54.6 volt
2 amps is a reasonable charge power for most battery packs, and charging at this level will make sure you get a long life expectancy out of your pack.
Charging Slower keeps the Battery Cells Cooler and that extends their Cycle Life.
Usage: If you plug it into the wall outlet first (which we usually recommend) it will not charge the battery.
