Hi all,
One of my customers has a 48V 20Ah battery. When he plugs it in to the bike nothing happens at all. He assumed this was the BMS so he asked me to put a new one in which I did the old one was in wrong anyway. It had the B- going to the charger/power out and the P- going to the negative on the battery. Anyway, new BMS and still the same problem. The battery accepted the charge and measured 51.5V when it indicated full but on the bike it does nothing.
However, when you attach the charger to the battery when it is on the bike, the bike powers up fine and runs.
So: The battery is measuring the correct voltage but does not power the bike unless the charger is plugged in.
Any thoughts?
Thanks
Karey
