SANDISOLAR 300Ah LiFePO4 Battery 12.8V 3840Wh Lithium Iron Phosphate Battery Expandable for Home Solar Energy Storage

Feature

1.Massive Energy Storage Capacity
Experience reliable power with a nominal voltage of 12.8V and a rated capacity of 300Ah, delivering a substantial 3840Wh of energy. This high-capacity unit is designed to replace heavy lead-acid batteries, offering a lightweight and compact solution (384204272mm) for your energy needs.

2.Ultra-Long Cycle Life
Built for longevity, this LiFePO4 battery boasts a cycle life of up to 6000 times (at 25°C, 0.5C, 80% DOD). It is a durable, long-term investment that significantly outperforms traditional battery chemistries, reducing the frequency of replacements.

3.High Power Output & Efficiency
Engineered for high performance, the battery supports a Max Continuous Charge and Discharge Current of 150A. It delivers a continuous output power of 1920W, making it suitable for powering heavy-duty appliances and handling rapid charging from alternators or solar systems.

4.Advanced Safety & Protection
Housed in a flame-retardant ABS plastic case with an IP65 protection rating, this battery is built to withstand harsh environments. The internal structure prevents leakage and explosion risks, and it includes safety features to prevent short circuits and overheating.

5.Versatile Solar & Charging Compatibility
Optimized for renewable energy, it works seamlessly with solar panels (recommended ≥600W) and MPPT controllers. It supports a CC/CV charging method with a recommended charge voltage of 14.6V, ensuring efficient energy harvesting from the sun or shore power.
Flexible Installation & Scalability

6.The battery can be mounted in any position (including upside down) and supports series and parallel connections up to 4S4P. This allows you to build larger battery banks (up to 8 identical batteries) to increase voltage or capacity for off-grid systems.

7.Wide Operating Temperature Range
Designed for all-weather reliability, the battery operates efficiently in discharge temperatures ranging from -20°C to 60°C and charging temperatures from 0°C to 55°C. For long-term storage, it is best kept between 10°C to 35°C.
Smart BMS Protection

8.Equipped with a Battery Management System (BMS) that protects the cells from overcharging, over-discharging, and short circuits. If the BMS shuts off for protection, the battery features an auto-recovery mode or can be easily activated via specific charging methods.

9.Premium Build Quality
Features robust M8 terminals for secure connections and includes insulating caps to prevent accidental short circuits during storage. The internal resistance is kept low (≤10mΩ) to maximize efficiency and minimize energy loss during high-current operations.
