We are always at your service.Camera batteriesType: Pack Chemistry: Li-ion Nominal Voltage (V): 3.7v Capacity (mAh): 750 Max Continuous Discharge Current: 0.75A Max Discharge Current: 0.75A Battery Charging Current: 0.8AWeight: 70g Dimensions: 6.5*5*25px 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.
