Hi Product Hunt! 👋 I'm Mateusz, the maker of BMS Monitor. BMS Monitor helps you understand what is happening inside your LiFePO4 battery through a clear dashboard connected to a compatible JK BMS over Bluetooth. You can check charge level, individual cell voltages, current, temperatures and alarms. It is designed for people using batteries in campervans, RVs and DIY solar installations. Battery data stays on your phone, and monitoring does not require an account. Local history records while your phone is connected and within Bluetooth range. Compatibility depends on your exact BMS model and firmware. This is an independent app and is not affiliated with JK or Jikong. I'd love feedback from people using these systems. Which BMS model do you use, and what information matters most when checking your battery?
