Advantage:

1. Large capacity:18650 battery pack calculator is at least 1200mah or more, even reaching 3600mah, and the average battery cell is only about 500;

2. High energy storage efficiency and good stability: 70° environment can maintain full performance output, while internal protection circuit is generally protected against battery burnout;

3. Almost no memory effect: do not need to put all the remaining power before charging, can be charged and put at any time, easy to use;

4. Charge and discharge cycle life is high: the number of cycles of lithium battery is tens of thousands of times and the high temperature resistance is very good;

5. Environmental protection, non-toxic substances: non-toxic, harmless, non-polluting, RoHS certified.


Features:

1. Longer storage life than NiMH Batteries

2. Light weight and higher energy density than any rechargeable battery

3. Installed IC chip will prevent the battery pack from over charge and over discharge.

It helps protect battery chemistry integrity and prolongs battery life.

4. Installed polyswitch will cut off power if battery discharge current more than 6.6Ah

5. Perfect for building up battery pack for medical equipment Back-up or EPS Emergency Power

6. Supply which requires compact size and lighter weight

7. The battery module is wrap by PVC


Others:

1. OEM orders are available

2. Superior quality and cost-performance ratio

3. Tags, plugs and connectors are available

4. We could design and produce the battery pack with plastic shell and assembly procession for customized configurations is available (we could design and develop Li-ion battery according to your product work performance & structure apprearance)
