51.2V 105Ah LiFePO4 Battery with Heater -30℃ Charge IP67 for RV Solar Marine

All Weather Performance with Built in Heater
This 51.2V 105Ah LiFePO4 battery is engineered for extreme environments. The built in heating system automatically activates when charging below 0°C, allowing safe charging at temperatures as low as -30°C. Discharge is possible from -30°C to 65°C, making it ideal for cold climate solar storage, off grid cabins, RV winter camping, and marine applications in northern regions. No external heating pads or additional thermal management required.

Core Electrical Specifications
Nominal voltage is 51.2V with 105Ah rated capacity and total energy of 5376Wh. Internal resistance is ≤45 milliohms. Efficiency reaches 98 percent. Self discharge is less than 5 percent per month. The battery uses 16 cells in series with 1 parallel string (16S1P). Dimensions are 460mm length, 334mm width, and 247mm height. Weight is 46 kilograms. Terminal type is FCC1020 rated for 200A. Housing is SPCC steel with IP67 dust and water protection (fully submersible for short periods). Communication interfaces include RS485 and CAN.

Discharge Performance
Continuous discharge current is 150 amps, capable of powering a 5000W inverter or multiple heavy loads. Pulse discharge current reaches 250 amps for less than 120 seconds, handling surge loads from motors, pumps, and compressors. BMS discharge cut off voltage is 40V with reconnect at 43.2V. Short circuit protection activates within 300 to 800 microseconds.

Charge Parameters
Charging uses the CC CV method with charge voltage range of 56.8V to 58.4V. Recommended float voltage at full charge is 53.2V to 53.6V. Recommended charge current is 52.5 amps for optimal cycle life, while the maximum charge current is 105 amps for faster charging. BMS charge cut off voltage is set to 58.4V.

Cycle Life and Longevity
Cycle life exceeds 4000 cycles at 100 percent depth of discharge while retaining over 80 percent of original capacity (tested at 25°C, 0.5C charge/discharge). For daily cycling, this provides over 10 years of service. The low self discharge and robust construction ensure reliable operation even after years of use.

Rugged IP67 Enclosure
The SPCC steel housing with IP67 rating is completely dust tight and can withstand immersion in water up to 1 meter for 30 minutes. This makes the battery suitable for outdoor installations exposed to rain, snow, and pressure washing. It also resists corrosion and mechanical impact.

Communication and Monitoring
RS485 and CAN ports enable direct communication with leading inverters including Victron, Growatt, Deye, Sofar, and Luxpower. Real time data includes voltage, current, temperature, state of charge, and fault codes. This allows the inverter to optimize charging based on battery status and enables remote monitoring via energy management systems.

Applications
This 51.2V 105Ah battery is ideal for off grid and hybrid solar systems in cold climates where winter temperatures drop below freezing. It powers RVs and campervans for four season camping. It serves as a marine house bank for sailboats and yachts in northern waters. It also works for telecom backup, industrial UPS, and small commercial energy storage where reliability in harsh conditions is required.
