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 200A continuous discharge current and a 400A peak current (for 5 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.

Important Usage & Storage Tips For long-term storage, it is recommended to charge the battery to approximately 80%. If storing for extended periods, ensure the battery is charged at least once every 3 months to maintain health and performance. Always store in a dry, cool place, away from fire and direct heat sources. Avoid directly short-circuiting the positive and negative terminals.
