10kwh 50 kwh 48 volt solar batteries lithium ion battery 48v 100ah for solar system

>Manufacturing techniques

1. Top quality battery cell, with brand new A grade prismatic LFP aluminum shell battery cells,high energy density,6000+ long cycle life. Every battery cell was with a Unique QR code, can be traceable.

2. There have a BMS to protect the battery, the BMS can provide the protection functions as Cell balance control, Over-charge protection, Over-discharge protection, Short circuit protection, High/Low temperature protection.

3. Laser welding, the battery pole and the busbar was welded by laser, more reliable and efficient .

4. 100% tested before packing, every battery pack passed the aging test and charge/discharge test, to ensure that all the products we produced accord with the highest quality standards.
