10 kW
After 20 years of building Ebikes, this is the worst electrical fault conceivable: On a 14S lipo battery, there's a bad wire so the BMS actions LVC low-voltage-cutoff, so the battery switches off every 20 minutes, possibly 10 miles from a road in a ravine.
The battery is stuck together with hot-glue, a dense cardboard cover from a xxx comic, duct tape, solder, GPS tracker, padding and I already looked at it 30 minutes and no hope of finding the faulty wire. Plus, there are VERY bad quality BMS's being sold as "premium YIT blue/red anodized alu" and they fail a lot faster than the 12 dollar OEM BMS's that are now unobtanium, so it could be the BMS that has a fault, even if I change all the wires.
It hits me that the best option is to bypass the BMS and keep an eye on the volts, rather than even attempt to service the hot glued battery!
