We are always at your service.Mobile Phone batteriesType: Pack Chemistry: Li-ion Nominal Voltage (V): 3.7v Capacity (mAh): 1100 Max Continuous Discharge Current: 1.1A Max Discharge Current: 1.1A Battery Charging Current: 0.8AWeight: 50g Dimensions: 6.5*5*12.5px Avg. Temperature Ranges for Charging: <55℃Discharging: 45℃Storage: 25±5℃PCB/Pack Protection(for single cell voltages): Over Charge Cutoff Voltage: 4.35 ± 0.025V We have two types of battery cell for the pack: 18650 lithium battery andlithiumpolymer battery. As for the raw material of the battery cell, we canuse NCM or LiFePO4 according to customer’s specification. Comparedto NCM, LiFePO4 has longer cycle life and is more safer, but of course the cost would be higher.We will prepare detail proposals for our customeraccording to their specification.
