IN STOCK: 15s BMS v2.
I am proud to say that this BMS is open source If any component goes bad, I have a full parts list on GitHub, and it is designed to be easily repaired. This BMS comes with a 30-day, no-questions-asked warranty.
This is a drop in replacement for the stock pint and XR BMS. It includes a passthrough design similar to the Stock BMS. Note: Polarity already reversed for Stock FM battery do not use this BMS for any other application other than 15s and for XR and pint One wheel that have been converted to VESC. Please check the stock FM harness the polarity may have to be switch on the other end of the controller.
Features:
- Charge-only configuration
- Balances cell voltages only during charging
- Offers overcharge protection to prevent cell damage.
- Overheat battery protection- Will stop charging at 55c to 60c
- Sleep mode during low pack voltage
- Plug-and-play design for Pint and XR VESC conversions

Before I bought this I tried a Flipsky BMS with a Maxkgo 15S stock breakout board (for my XR VESC) and I accidentally connected 2 of the cells wires while soldering balance wires onto the breakout terminals. I think I ruined the flipsky BMS. This one costs barely more money but it is super simple and requires minimal soldering, for a easy BMS swap if your FM BMS dies.
Bonus points, on the PintX VESC project this works really good and it will fit inside the battery box with lid completely closed! Unlike the (Flipsky, Maxkgo, ZBMS) type.
Get some XT30 connectors and solder one to the power plug wires, and another with a little wire going to the charge terminals on the board, for an easy disconnect if you need to work inside the battery box without the BMS getting in the way.
This was not “drop in ready” as advertised. An XT30 connector had the be soldered onto the board for the battery connection. Otherwise works fine, just miss leading if you’re looking for something less involved
