Key Selling Points
- Longer Lifespan: 6000 cycles (vs. 300–500 for lead-acid) → Lower replacement costs.
- Smart Protection: 4S100A BMS prevents overcharge, over-discharge, and short circuits.
- Scalable Storage: Supports 2-series (25.6V) and 2-parallel (200Ah) for custom energy capacity.
- Safe & Stable: LFP chemistry avoids thermal runaway; IP20 rating suits dry indoor use.
- Lightweight Upgrade: 10.5KG (≈50% lighter than lead-acid) → Easier installation.
Applications
- Home backup power
Keeps essential devices running during blackouts: powers routers (10W) for 256 hours to stay connected, mini fridges (120W) for 21 hours to preserve food, and LED lights (5W) for 512 hours—acting as a quiet, efficient energy source without the noise of fuel-powered alternatives. - Off-grid living & camping
Pairs seamlessly with solar panels to store daytime energy, providing reliable power for RV appliances (microwaves, TVs) or remote cabin utilities. As a lithium battery generator component, it replaces bulky fuel generators, reducing carbon footprint and operational costs. - Disaster relief & emergency response
Delivers steady power to charge phones (5W) for 512 hours, run portable oxygen concentrators (300W) for 8+ hours, or operate small radios—critical for communication and survival during storms, earthquakes, or other crises. Its lightweight design (22.5KG) makes it easy to transport, fitting the needs of a mobile lithium battery generator setup.
