703040 Rechargeable 3.7v 850mah Lithium Polymer Battery for high power discharge rate

Features

1. High Energy Density: Li-Po chemistry offers a high capacity-to-size ratio, providing 850mAh in a compact, slim form factor (7.5x30x40mm).

2. Flexible Form Factor: The pouch cell design allows for a thin and relatively flexible profile compared to cylindrical cells.

3. High Discharge Rate: Capable of supporting discharge rates suitable for high-power applications (up to 1C continuous, with protection allowing higher pulses).

4. Long Cycle Life: Can withstand over 500 charge-discharge cycles while maintaining more than 80% of its initial capacity.

5. Integrated Protection Circuit ( typical): Often includes a Protection Circuit Module (PCM) providing:

   • Overcharge Protection: 4.20V ± 0.05V

   • Over-Discharge Protection: 2.7V ± 0.1V or 3.0V ± 0.1V

   • Over-Current Protection: 3.0±1.0A or 2.0±1.0A

   • Short Circuit Protection

6. Low Self-Discharge: <3% per month (at room temperature).

7. No Memory Effect: Can be recharged at any state of charge without capacity reduction.
