Hebei Mutian Solar Energy Technology Development Co., Ltd. is one of the most reliable manufacturers and suppliers of 51.2v300ah lifepo4 battery in China, also supports customized service. Welcome to buy advanced 51.2v300ah lifepo4 battery in stock from our factory.
Product Features & Competitive Advantages-51.2V300AH LiFePO4 Battery
The use of advanced lithium iron phosphate (LiFePo4) chemistry provides for low risk of runaway thermal events, extending the expected service life of the product.
The intelligent battery management system (BMS) consists of an active balancing design, monitoring voltage and temperature for each cell, and being able to communicate with externally mounted diagnostics devices through CAN and RS485.
The BMS has been designed to support a wide range of applications, including high power loads up to 200 amps of continuously delivered power.
Designed to operate reliably over a temperature range extending from -20 to +60 degrees Celsius, this product is well suited for the more extreme applications.
Modular design – allows parallel connection for capacity expansion (up to 15 units in parallel).
Pre‑charge circuit – protects inverter capacitors during startup.
Operational notes:
Store in a cool, dry place between 0°C ~ 35°C for long‑term standby.
Recharge every 6 months if not in use.
Ensure proper torque on terminal bolts (recommended 8‑10 N·m) to avoid loose connections.

Frequently Asked Questions (FAQ)
Q: What is the best charge and discharge current to maximise lifespan?
A: The best cycle life is to charge at a rate of 0.5C (150A) and to discharge at 0.5C (150A) - continuous. If you were to continuously operate to a rate of 200A, although drastically reducing the life of the battery, it would still impact the overall cycle count slightly.
Q: Does it come with a display or monitoring software?
A: The LCD display included with this unit provides a real-time monitor of the following information: voltage, current, SoC, and temperature; and includes the ability to download PC software/mobile app (RS485/CAN connection) for live monitoring of all performance data.
Q: What is the warranty period?
A: The warranty on this unit is for 10 years, or for 8,000 cycles, whichever occurs first, as long as the unit has been operated at its standard specifications.
Q: Is the battery waterproof?
A: The enclosure is IP65 rated – dust‑tight and protected against low‑pressure water jets. Not suitable for submersion.
Q: How should I dispose of this battery at end‑of‑life?
A: Please return it to a certified recycling facility. We provide take‑back services in many regions – contact our support team.
