3.7v 200 mAh Rechargeable Lithium Battery LiPo cells 402030 200mAh for Arduino

Electrical characteristics：   1. Standard Charging method ：0.5C （constant current）charge to 4.2V,then CV(constant voltage 4.2V)charge till charge current decline to ≤0.05C 2. Rated Capacity ： The capacity means the discharge capacity of the cell, which is measured with discharge current of 0.2C with 3.0V cut-off voltage after standard charge. 3. Charging time ：Standard Charging：3.0 hours(Ref.) ，Rapid charge： 2.0 hours(Ref.) 4. Max. charge current ：1.0C Max. discharge current ：1.0C Discharge cut-off voltage ：3.0V 5. Operating temperature ：Charging： -20℃~60℃ Discharging：-20℃~60℃ 6. Storage temperature ： -10℃~ +45℃ 7. Cycle life: 400 cycles,Stable performance with 100% in house testing   Test condition： Charge:0.5C to 4.2V Discharge:0.2C to 3.0V 70% or more of 1st cycle capacity at 0.2C discharge of Operation  Self-discharge ：Residual capacity >90% After the standard charging, storied the cells under the condition for 30 days, then measured the capacity with 0.2C till 3.0V   Temperatu
