MuscleGrid 8S Active Balancer is a capacitive cell equalizer that transfers energy between cells to keep your lithium pack in balance — detecting voltage differences and redistributing charge automatically with minimal heat. Faster, cooler balancing than a passive BMS, for more usable capacity and longer pack life.
Key features
- Up to 8S — LiFePO4, Li-ion & LTO (cell range 1.8–4.5V)
- Up to 5A active balancing — far faster than passive BMS on big packs
- ±5 mV accuracy · energy-transfer (capacitive) balancing, low heat
- Very low standby draw (<0.1 mA sleep) · plug & play
Ideal for
- 30Ah–300Ah lithium packs
- E-rickshaw & e-bike systems
- Solar / inverter battery banks
- DIY & integration builds
