Hey everybody my name is Colin this is my first post. I'm pretty new new to E-Bike building but i recently built an e-bike with a 500 watt 36 volt hub motor. I got a used 36 volt lithium battery pack from an electric scooter. My initial problem was the Bms would cut off power at 300 watts (the scooter had a 250 watt motor) so i replaced the Bms using this tutorial http://wiki.myelectricscooter.org/fr/xi ... _generique
and this bms from amazon https://www.amazon.com/gp/product/B073V ... UTF8&psc=1 .
for about three months everything worked perfectly and then all of a sudden this morning the battery was reading 15.6 Volt. im very confused that bms shouldn't allow it to discharge below 32 volts. also when the battery is plugged in it reads 42 volts. The only thing i did differently than the tutorial is instead of soldering a socket for the charger i soldered the charger directly to the bms. Could that be the cause of this problem or is it more likely to be a short or loose connection?
