Hello,
I have an homemade e-bike and got a battery problem.
When I arrived to the bike one day, I noticed that it didnt get charged during the night at all.
I had ran out the battery during the previous day.
I have a 1000w 36W hubmotor connected to a Vpower 36V 10A LIFEPO4 [
http://vpower.hk/product.php?id=18] and a 6A charger.
It follows with an BMS, a board for battery protection so I feel safe that I did not over-use the battery but rather that the BMS board [
http://vpower.hk/product.php?id=114] can be broken.
I saw that one cable soldered from the charger was partially burned off, and I repared that cable to no avail.
The battery has ~33V of voltage and the charger outputs ~45V. When I plug the charger in the bike (with a normal ampere running), everything works but it does not charge the battery.
What could the problem be? I could try to troubleshoot it with my voltmeter if needs to be.
