Review on EVAPLUS 42V 2A DC Charger Power Supply Adapter for 36V Lithium Li-ion Battery - 5.5mm/2.1mm Prong Connector by Alejandro White

when i connected it to my e-bike for the first time (that was on the last bar) it turned green (charging) instead of red (charging) . I let it sit for a while hoping it would run over on red but it stayed on green. There is no way of telling when the bike is done charging. Either I have a defective charger or it just doesn't work. I bought another charger from another company and it worked. Popped it into a dead battery and it turned red so I knew it was charging.
