Open Battery Information is an Arduino firmware plus browser-based tool for reading status, cell voltages, temperatures, charge cycles, and error codes from locked battery pack BMS chips (currently Makita LXT). It helps diagnose and revive batteries whose BMS has locked out after a fault, using the Web Serial API with no software installation.
Use cases
- unlock a locked makita lxt battery pack
- read cell voltages and error codes from a dead power tool battery
- diagnose why a battery bms locked out
- check charge cycles on a battery pack before repair
- flash arduino firmware from the browser without installing toolchains
- reset a bms after a temporary fault was repaired
When to choose
- you have a locked or dead power-tool battery you want to diagnose or revive
- you want a browser-based, no-install tool that talks to an Arduino over Web Serial
- you prefer a privacy-friendly tool that runs entirely locally
When to avoid
- your battery brand or pack type is not yet supported by the OBI interface
- you need a fully software-only solution without Arduino hardware
- you want to bypass BMS safety locks on genuinely faulty batteries
