BMS For 16 cell, 48v volt Lithium-iron-phosphate DIY batteries.
100 amp continuous charge or discharge current.
Low Temperature Charging cutoff at 0c.
The Apps allow you to monitor SOC (state of charge), Current, Voltage, cell balance, temperature, and more.
Bluetooth Module is included, Balance wires are included, USB module is an additional purchase.
If you choose to add crimped copper lugs, the high current wires will be hydraulically crimped into a single tinned copper lug on each side, and finished with heat shrink tubing.
Final assembly, testing and calibration is done in Naples, Florida. Units with 8 gauge wires and/or crimped lugs are assembled in Naples, FL. The BMS is manufactured in China.
To view or change Parameters, there are 3 ways to connect to the BMS. All 3 applications are free.
- iPhone App: Overkill Solar Mobile App
- Android App: Overkill Solar Mobile App
- USB module to PC/desktop application.

FYI for experimenters: The BMS communicates with a 5v TTL UART at 9600 baud. It is directly compatible with Arduinos, etc.
We have written a new Arduino library for the BMSs, now available on the downloads page. The beta version allows you to read all the monitoring parameters and switch charge and discharge on/off. Future releases will have full read/write capability. A python library is also in the works.
