Battery production process
battery cell cabinet
All batteries need a second sub-capacity，to ensure the battery capacity.
1. Automatic sorting machine
High-tech machine,advanced technology,ensure the battery cells we need in the same weight, internal resistance, voltage, capacity
2. Bracket combination
Used the most secure combination of brackets, good cooling effect and more reliable.
3. Battery spot welding
Pure nickel spot welding, small internal resistance large over-currrent.
4. BMS systerm
With over charge protection over discharge protection. Excess charge current protection.
5. Epoxy board packaging
Flat and beautiful appearance. Security protection.
6. Charge and discharge test
Aging test,charge and discharge cycle testing for each battery pack, we guarantee to the customer each battery pack with the best quality.
1.Dual IC chips, that can anti-shortcircuit, anti-overcharger, anti-overcurrent, anti-overload;
2.Injection Technology to make battery more stable;
3.With short-circuit production function, safe and reliable;
4.Up to 500 cycles life,low self-discharge,no memory effect;
5.Factory mastered technology and competitive price;
