Features
- 6,000 Cycles: Powered by Grade A prismatic cells with higher energy density than cylindrical cells, our battery excels with an impressive 6,000 cycles of endurance.
- Series/Parallel Connection: Configure our batteries in 2s & 2p setups for maximum potential, ensuring sufficient power output during power outages and hurricanes.
- Powerhouse Performance: With a continuous discharge of 100A/150A/200A and a pulse discharge of 200A/300A/400A, our battery effortlessly powers fridge, air conditioner and kettle.
- Smarter BMS: Upgraded for overdischarge, overcharge, over-current, short circuit, high/low temperature, and charging current protection, minimizing cell degradation.
- Quick Recharge: Our battery charges swiftly compared to AGM batteries, thanks to its lower internal resistance and a maximum charging current of 50A/75A/100A.
- Enhanced Usable Capacity: While AGM batteries are typically limited to 50% discharge, our lithium LiFePO4 battery safely allows discharge to 80~90%.
- More Power, Less Weight: Only weighs 12 kg/20.6kg/27.7kg (equivalent AGM weighs approx. 34 kg/64kg/83kg), our lithium batteries double the usable power for extended 4WD adventures.
- Rugged Reliability: Equipped with prismatic cells for enhanced vibration resistance, our batteries ensure reliable performance even in the toughest conditions.
- Massive Capacity: Eliminate the need for multiple batteries – our single 135Ah/220Ah/300Ah battery will get the job done, providing massive capacity for your power needs.
- Minimal Self-Discharge: Our lithium-ion battery boasts a lower self-discharge rate, preserving its charge for months, always ready when you need reliable power.
