- 【Portable & Lightweight Design】 – Weighs only 13lbs (1/3 of lead-acid) with 1/2 the volume, saving space and reducing equipment load. Solid top handle for easy carrying during camping/fishing/off-grid work. Fits tight spots lead-acid can’t. (*Note: Not suitable for golf carts.)
- 【50A BMS with Comprehensive Protection】 – Safety is paramount. Premium automotive-grade LiFePO4 cells ensure stable charge-discharge, avoiding burning/explosion under short circuits, overcharging, extrusion or puncture. 50A BMS balances cells and protects against over-charge/discharge, over-current, over-temperature & overload.
- 【High Energy Efficiency & Long Lifespan】 – 5000+ deep discharge cycles (8-10x more than lead-acid’s 300-500 cycles) for 10+ year use. 2000+ uses at 100% discharge, 5000+ at 50% (recommended) with no performance loss. Lead-acid lasts ~2 years. Reduces replacement costs, ideal for RVs, solar systems, fishing boats & off-grid setups.
- 【Expandable Power】 – Easily connect in series (24V/36V/48V) or parallel (max 200Ah) to meet power needs. 4 units in series support 48V 2400W motors. Recommend limiting series/parallel connections to 4 for optimal stability & safety.
- 【Wide Compatibility & Reliable After-Sales】 – Suitable for household energy storage, UPS backup, CCTV, trolling motors, houseboats, 12V routers & air pumps. 12-month warranty + 24h customer service. Read manual before use; prompt issue resolution for worry-free purchase.
