Taidacent Low Internal Resistance Long Cycle Life Bluetooth Speaker nimh aa 14500 2S 7.4V 600mAh 25c Lithium Battery Pack
Model number; 14500-2S Capacity; 600mAh Voltage; 7.4V Size; H15*W31*L52(MM) Features; voltage, capacity, size can be customized. Application areas; power tools, household appliances, energy storage lamps. The main features of lithium battery: Sizes can be customized according to customer requirements (all sizes are negative tolerances). Low internal resistance, high discharge platform and fast charging time. The battery circuit protection board (PCB protection IC board) can be added as required to have good safety performance, with over-charge protection, over-discharge protection, short-circuit protection, and over-current protection. Overcharge detection voltage, overcharge detection delay time. Overcharge release voltage, overdischarge detection voltage. Overdischarge detection delay, over discharge release voltage. Overcurrent detection voltage, overcurrent protection current, detection delay time: Low internal resistance, high discharge platform and fast charging time. It can be equipped with protection board (PCB protection IC board) with good safety performance, overcharge protection, over discharge protection, short circuit protection, over current protection, overcharge protection voltage, over discharge protection voltage, over current protection. Working discharge temperature: -20 ° C ~ +60 ° C. Long cycle life: After 500 cycles of continuous charge and discharge, the battery capacity is not less than 80% of the rated capacity. The storage time is long and the voltage drop is small, and the self-discharge is small.
