Ameec Shenzhen Technology Co.,Ltd, with professional solar power batteries factory, is a best China solar power batteries, 18650 battery, lithium battery, polymer battery, lithium ion battery, lithium polymer battery, rechargeable batteries manufacturers and suppliers. We are always at your service. Solar power batteries Type: Pack Chemistry: Li-ion Nominal Voltage (V): 7.4v Capacity (mAh): 8000 Max Continuous Discharge Current: 24AMax Discharge Current: 48A Battery Charging Current: 2AWeight: 8kg Dimensions: 30*20*500px 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.
