Flashing red caution light on Super Soco battery BMS board
So. I opened my battery. And during that, I caused a brief but energetic short-circuit. Pop!
The battery still has the correct voltage, but now a red light is flashing on the BMS, and the scooter doesn't like it. It gives errors 90 and 92 (over current; over voltage).
What does the flashing red light mean, and how do I get my battery working?
Any help would be much appreciated.
I don't know what red flashing light means, and except the manufacturer nobody knows (or hope I'm wrong), but it's very probable you burned some circuits on BMS which are reading and communicates with instrument cluster.
Just check visually the BMS, some smell from burnes circuits... if it's only a capacitor or resistor (which I doubt), you may have luck, if it's an IC, it would be more complicated. Maybe give the BMS to an electronist, he can measure and try to find out.
Anyway sorry to hear that.
maybe a BMS reset helps.
You have to apply a higher voltage then the battery voltage to do that.
If nothing is working, I´d be happy to buy the battery 😀
Update: As it turn out, the problem with the battery's BMS circuit board is that the components under the heat sink have overheated and cracked open. Dead.
So the lesson is: Keep an eye on the battery temperature. It's quite possible to overheat and kill a BMS through normal use.
If anyone is interested, I was able to replace the BMS board with a new one from Motorino. I also added a little volt meter to the top of the battery. The Anderson connector lets me plug into the bike in parallel with the regular connector.
