MuscleGrid 15S 100A Smart BMS protects and manages a 48V LiFePO4 battery pack — monitoring every cell, cutting off on fault, and balancing the pack while it charges. CAN + UART/RS485 communication and a Bluetooth app give you full visibility of cell voltages, current, temperature and state of charge.
Key features
- 15S LiFePO4 (48V nominal) · 100A continuous discharge
- CAN + UART/RS485 communication for inverters & ESS
- Bluetooth app — live cell voltages, current, temperature, SOC
- Full protection: over-charge, over-discharge, over-current, short-circuit, over-temp
- Passive cell balancing · dual NTC temperature probes
- Note: this is a BMS controller — not a charger
Ideal for
- 48V solar / energy-storage (ESS) packs
- E-rickshaw & EV lithium banks
- Inverter & UPS battery banks
- Industrial & DIY LiFePO4 builds
