14Series lithium battery Protection Circuit Module


DLS16B14B-01T40AThis specification applies to the 14Series lithium  battery Protection Circuit Module  Products are RoHS compliant.


With over charge function, over discharge function, over current protection, short circuit protection, temperature function, charging balance management function and so on.

  1. Feature

Apply seiko solution which is IC A grade protection

With strong loaded, constant discharging current is 40A, MOSFET with high stand voltage and low conduction internal independence. Cooling fin effect is good。

IC have power balancing function, current could be adjusted by improve the MOSFET。

Over charge protection, over discharge protection, typical voltage detection method.Over current, short circuit protection, short circuit protection performance is stable and reliable, long time load short circuit will not affect the protection board and electric core

Temperature protection during charge and discharge。

Temperature drift is tiny, the accuracy is 1% high power package  detection resistance。

Extremely low power consumption, the whole machine consumes less than 50uA。

PCBA surface with high corrosion resistance, high permeability, high impedance coating ESD paint three.

The direct series combination of 14 supported multi compound lithium power battery。
