Rental ES4 BMS

Postby Bruce Oc Thu Dec 05, 2019 3:32 pm

Hello, I have a legal prior rental ES4 and I have some issues.

1. The external battery only charges to 80%
2. Removed the external battery and the scooter charges normally. Put the external battery back on and it Shuts off after sitting idle for a short period of time.

I tried using ninebot flasher but after it gets to updating step it just beeps and never finishes. Any insight would be appreciated.

Im going to assume we both got Jumps from the same San Diego location lmao and I’m in the same boat. I have tried downgrading the BMS using the BMS141.bin.enc and flashing using ninebot flasher but it stays on 3.0.3 no matter what I do...
