Same cells, same capacity — the difference is the BMS and monitoring hardware.
Same battery either way — choose the cover that fits how you'll use it.
And even if your warranty has expired — in any case — we will still support your battery with repairs, charging only the part and labour cost.
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.
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.
2.9 kWh of LiFePO4 backup you can carry. The Signature Series 24V 120Ah is built for 24V inverter systems — home backup, shops, and solar setups that need dependable deep-cycle storage without the weight and short life of lead-acid. A built-in display shows live voltage, current and charge, and Bluetooth lets you check the pack from your phone.
