Power Your Adventures with the 12.8V 300Ah LiFePO4 Lithium Iron Phosphate Battery

Unleash long-lasting, reliable, and safe power for a wide range of applications. Whether for solar energy storage, marine use, RV trips, camping, or backup power, this high-performance battery is engineered to deliver.

Key Features & Benefits

• Massive 300Ah Capacity: Provides extended runtimes, powering your devices and appliances longer than standard batteries.

• Exceptional Cycle Life: Enjoy over 2000 cycles at 100% Depth of Discharge and up to 5000 cycles at 80% DoD. This longevity makes it 4x more cost-effective than traditional lead-acid batteries.

• Superior Safety: Built with stable Lithium Iron Phosphate (LiFePO4) chemistry, which is highly resistant to thermal runaway, ensuring safety even under demanding conditions.

• High Power Delivery: Supports a 100A continuous discharge current and a 180A peak current (for 3 seconds) to start heavy-duty equipment and handle high surge loads.

• Wide Operating Temperature: Can be discharged in temperatures from -20℃ to 60℃, making it suitable for harsh environments.

• Lightweight & Compact: At only 26.14kg, it is significantly lighter and more space-efficient than lead-acid batteries of similar capacity.

• Zero Maintenance & No Memory Effect: Always ready to use without the need for periodic full discharges or complex maintenance routines.

• Environmentally Friendly: Contains no toxic heavy metals, making it a green choice for production, use, and disposal.

• Very Low Self-Discharge: Loses less than 1% of charge per month, so it stays ready for action much longer when stored.
