Features

  • [High Capacity 15.36kWh, True 51.2V 314Ah LiFePO4 Battery] Measuring floor-standing design, this LiFePO4 battery delivers 15.36kWh of usable energy four times the power of a standard 12V 300Ah battery. Built with Grade A+ LiFePO4 cells and a reliable BMS, it provides stable, long-lasting power for home energy storage, solar systems, and off-grid applications. With a true-rated capacity of 300Ah at 51.2V, it keeps your appliances running longer. Backed by 6000 cycles and a 10+ year lifespan is designed for performance you can count on
  • [150A BMS with Low Temp Cut Off & Full Protections] This LiFePO4 battery built-in intelligent BMS supports 150A continuous discharge (0.5C) and offers complete protection against overcharge, over-discharge, short circuit, high temperature, and low temperature. With low-temp charging cut-off (below -10C), it's safe for cold environments. Whether you need a lifepo4 battery for solar storage or backup power, the advanced BMS ensures peace of mind
  • [Floor Standing LiFePO4 Battery - IP65 & 6000 Cycles] Upgrade from traditional lead-acid or smaller lithium batteries to this ANJ battery. Weighing only 115kg (approx. 253 lbs), it's lighter than equivalent lead-acid banks while delivering consistent power with no voltage sag. The IP65 waterproof and dustproof rating allows confident outdoor installation. With 6000 deep cycles (vs. 300-500 for SLA), this lifepo4 battery lasts 3-5 times longer, reducing replacement costs and hassle
  • [Scalable Parallel Expansion - Build Up to 61.44kWh or More] Supports parallel connection via RS485 communication. Easily connect up to 4 units to reach 61.44kWh (51.2V 1200Ah) for whole-home backup, off-grid cabins, or commercial energy storage. The auto-addressing feature simplifies setup. For larger needs, you can parallel more units. This 300ah lifepo4 battery in 51.2V makes system expansion simple and cost-effective
  • [Charging & Discharging Parameters] Compatible with standard solar charge controllers and inverters (via CAN/RS485). Recommended charging current: 150A (0.5C), max 150A continuous. Discharge current: 150A continuous, with peak capability for higher loads. Operating temperature: charging -10C55C, discharging 0C55C. Always use a LiFePO4-specific charger or inverter settings. Do not use SLA chargers to avoid damaging the battery
  • [Important Reminders] 1. Ensure all terminal connections are tight. Loose connections may cause heat buildup and reduce performance. 2. When fully discharged at high current, allow the battery to cool before recharging to prevent over-temperature protection. 3. For optimal lifespan, charge at 0.2C (60A) to 0.5C (150A). The built-in BMS will manage safety automatically. 4. Use the provided communication cables for parallel setups. Refer to the manual for DIP switch address settings

  • 2 units working together just fine
Units are working very well so far. 2 units were shipped but only one made it. After finally getting security video to them of the delivery (Amazon kept getting in the way) a replacement unit was shipped and has now been received and installed. Given the time difference, communication was very good. Communication to the inverter is via pylon and I sill need to get CANBUS to my monitoring computer (I will not be using the built in Bluetooth.) ... show more
