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.


Product Advantages:             

 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;
 6.CE/ROSH/SGS/UL/MSDS/UN38.3/IEC61233  standard.
