MuscleGrid Signature Series — the flagship
A large touchscreen shows live SOC, voltage, current and per-cell data, driven by the renowned JK BMS with active balancing. Full CAN / RS485 / RS232 communication and dual connectors for effortless parallel banks.
The MuscleGrid battery platform
Every MuscleGrid lithium battery is built on the same foundation: A+ grade LiFePO4 cells with laser-welded terminals — no bolted busbars to loosen over years of vibration — in a heavy-duty powder-coated steel body with dual lifting handles, MCB protection and a QR-coded service identity. Made in India, backed by pan-India doorstep service.
The flagship 51.2V battery — with the big touchscreen. The Signature Series 51.2V 120Ah gives you the same 6.1 kWh LiFePO4 capacity as our Thunder Pro, upgraded to the premium control hardware: a large touch display showing pack voltage, current, per-cell voltages and alarms at a glance, a JK Smart BMS with 1A active balancer, and CAN & RS485 inverter communication for true closed-loop charging with hybrid inverters.
Closed-loop matters: the inverter charges by what the BMS reports, not by a blind voltage curve — gentler on cells, faster to full, and the display shows it happening live.
