PGTech Lithium ion Battery Charger 10S 42V 5A DC Output XLR Plug for 36V Electric Bicycle Battery with Fuse

Purchased for charging a 10S LI Ion battery system to replace a cheap plastic charger that failed. Very nice construction with the aluminum case and the cable connector was high quality. The pin outs matched the STD for positive and negative voltages. The charger also came with a female connector port (nice add). The charger is very quiet even with the small case fan running, it also stays very cool to the touch. I have just started using but seams to be a very high quality product and the 5A output cuts the charge time >50% versus cheaper 2A models. I will try to followup after using for a couple of month but out of the box really nice piece of engineering.

I use the charger on a 17.5 amp hour Lithium battery for my Ebike. The built in fan keeps it cool, charges the battery fast, and has worked well for 6 months now. The two amp charger that came with the battery was so hot it caused me to look for a better charging solution, and this was it.
