Well what's your actual battery voltage measured with a multimeter? The BMS shows 100% capacity when you reset it, you have to charge it full then.

Raw value: Battery current: 3021 (358) 358 The BMS only limits the maximum charge current, the actual current is always set by your charger. A BMS is just a very...

The 30A version has 4 or 5 of these Mosfets in parallel: https://lcsc.com/product-detail/MOSFET_KIA-Semicon-Tech-KNB3308A_C176861.html I did measure them to have around 6-7 mOhm when driven at 12V by the BMS. So...

If you've only flashed the bootloader then you also have to flash the actual BMS firmware. Either through ISP or over serial UART with platformio. Read the README.md If you...

This schematic is totally fine, the warning was about modifying the ESC PCB. Also your brake light is missing a 2nd wire :p that'd be P-

The issue is reproducible with the latest code in this repository? Can you post the full output of debug_print here? The OCD error should clear automatically after 10 seconds and...

The versions above 30A have both sides of the PCB populated with mosfets and are thicker. 20A or 30A should be fine, I just went with 30A to be sure...

It's probably more reliable, yeah. And if you think it's the worth the trouble then go for it. I mainly did this so I can do 12S with my scooter.

OCD definitely works for me and others though.. :thinking: it's actually handled by the TI chip itself yeah basically "Serial protocol is crap" to fix it you can just do...
