【PRODUCT FEATURE】
[1] Use MCU and special software base on expert control system to realize intelligent optimization SOC control.
[2] Have temperature compensation function. Use outlay temperature sensor to control precision is higher than inlay temperature sensor.
[3] Have over charge,over discharge,over load,short circuit,defend counterattack etc protection.
[4] Use series connection PWM charge circuit.Charge return circuit voltage loss reduce one half than use diode.Charge efficiency is 3%-6% higher than not PWM, delay use time and life of products.
[5] LED indicating the system of charging, overcharge, power full, power low, over-discharge, over load,open/ short circuit, load on/off, etc.
[6] Use flash memory to save all work control point instead of adjustable resistance, to protect the control work point from going off as the adjustable resistance value is easily changed by temperature and vibration, in order to make sure the control accuracy and reliability.
