Description:   
10 PCS 2Cell String Lithium Battery Protection HX-2S-A2 Module [7.4V, 7A] is a lithium battery protection board, which is based on HY2120 2-Cell Lithium-ion/Lithium Polymer Battery Packs Protection chip. This chip is designed to protect two cells of rechargeable battery charging and also to detect high-accuracy voltage and delay circuits. The HY2120 chip series can be utilized for protecting the lithium-ion and lithium-polymer battery packs against overcharge, over-discharge, short circuit, and overcurrent conditions.
This circular board has MOS transistor to control the battery charge and discharge status, and also has an internal three-step over-current sensing circuit to safe wide various types of 3.7V  lithium-Ion batteries. The HX-2S-A2 module can accurately detect the battery voltage to control it. This module is a small, high performance, and low cost, that makes it a good solution for a wide range of battery protection requirement. this board is specialized for the 1850 batteries, but not be used for lithium iron phosphate battery hernia lamp, hand drill battery pack, electric fish machine battery pack, electric bicycle battery pack, children\’s car battery, 775 (4A)motor, 1W fish eye LED light.
