This is smart battery charger protection module with the various features of protections like Short circuit, Overcharge, Over-discharge, over current. Easy to install and convenient to use in all your DIY projects. High and accuracy voltage detection circuit charger using high voltage device was built with three stage over current detection circuit (Over current 1, 2, or short circuit). Transistor can control the battery charge and discharge and less the standby current consumption Specification: Over charge voltage: 4.25V to 4.35V (± 0.05V) Over discharge voltage: 2.3 to 3.0V (± 0.05V Max) Continuous current: 3A max peak current: 5A Working temperature: -40 to +50 Storage temperature: -40 to +80 Current: less than 3ua Resistance: less than 45m short cut Protection: yes, charge can repair Size: 36 x 6 x 1 mm (Approx.)
