I converted a Bird 590 to a personal scooter using a Chinese controller.
Everything is working great except sometimes the scooter just shuts off and does not turn on again.
When I try to turn it back on this happens:

If anyone ever experienced this please let me know.
I was thinking that this was caused by BMS but its better to ask first

thanks in advance!!

Certainly sounds like the BMS is shutting down to protect itself or thinking its protecting you. What is the voltage rating of the chinese esc? Could be its asking more than the BMS can give, causing the BMS to fault. Could also be a loose wire, faulty connector, erroneous firmware setting, but I'd tend to think it's the BMS. Have you tried flashing the BMS with different firmware if available?
