This is a standard charger that will work on all of our 52v shark and bottle packs which all have a 5.5 mm barrel plug.  The plug can be swapped out to be used with any 52v 18650 battery pack that needs a charger.

It charges to a maximum voltage of 58.8 then automatically stops charging. 

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.

    Light and compact, actually charges slightly above 2A so battery charges faster than expected. Has a cooling fan which makes a bit of noise, but nothing too dramatic.

    Works well. Did not see any indication that charging had stopped. Hi Josh, thanks for the review. Charging stops when the charger changes from Red to Green Regards Luna Mate

    Basic charger ,which never the less does the job intended of it. Seems to take a long time to charge, but I suppose that is better for the battery .

    Does its job. Somewhat noisy but seems good quality and it is pretty light if you need to bring it along for the ride.

    Charges the battery

    I bought a second one of these for work. Not that much to say - it does it's job. Worth noting that it contains a fan which is quite audible. Double edged sword. The fan stops when the battery is charged which is useful to confirm when it's charging, but can get a bit annoying on your desk.
