main feature:

1. The battery pack is safe, resistant to high temperatures and has a long cycle life.

2. The cycle life of the battery pack is high, in line with the concept of low carbon, energy saving and environmental protection.

3. The battery has a built-in BMS system with multiple protection functions. The protection system (PCM/BMS) adopts the most advanced chips and MOS from Japan and the United States.

4. The core materials include LiMn2O4 (lithium manganese oxide), Li-Ni-Co-Mn-O (ternary material), and LiFePO4 (iron-lithium).

5. can use imported Sanyo, Sony, Panasonic, Samsung, LG original batteries and domestic brand-name batteries as a combination unit, to ensure the consistency of the battery, stability, safety.

6. can be more and more string combinations and battery modular design.

7. The battery has built-in heating device. Under the condition of extreme low temperature, the host provides voltage to heat the battery. Allow the battery to operate within the proper temperature range.

8. Waterproof IP65 is suitable for outdoor photovoltaic power station.

 

3. Product performance

3.1 The battery pack has good low temperature performance, product safety and reliability, and good stability;

3.2 The battery pack has waterproof, dustproof, anti-drop, anti-corrosion, radiation protection, anti-electromagnetic interference;

3.3 The battery pack has multiple protection functions such as over-charge protection, over-discharge protection, over-temperature protection, over-current protection, and short-circuit protection. The BMS system can be built-in according to the needs of customers.

3.4 The battery pack has a small size, light weight, small self-discharge, long cycle life, high conversion efficiency, deep charge and discharge, long-term use and easy to carry.
