I finally got my battery in the mail today, but I've hit a wall
Both the battery and the charger are from em3ev.
The battery is 36v and 20 Ah.
The charger is 42V and 2A. It doesn't have a voltage selector switch
When I took the battery out of the box, the indicated had only 1 flashing red light. This means it's not charging and it has 0% - 10% charge. I plugged in the charger, but the charger has a light that means "Disconnected or full charge." I left the charger plugged in for an hour and a half, nothing changed.
The battery won't stay on for more than a few seconds unplugged.
I tested the charger with a multimeter, I measured 42V which matches the spec, and It put out brief spikes of 2A. The rest of the time it's 0A. I'm guessing those spikes are how it determines if it should charge or not.
I tested the battery and got around 35V for a fraction of a second before the battery turned off. When it's off, I get a reading of 3V. I tried connecting it to the bike and got a similar result. The screen turned on for a fraction of a second, then the battery turned off.
I'm not sure what to do now. This is my first ebike, so I don't have a lot of experience to draw on.
Please help.
