EZPHYSIKX TP4056 / TP 4056/TPA4056 Micro USB BMS KIT/Module with Over Charge & Discharge Protection for 18650 3.7v Lipo,Lithium Ion Battery Charging for Electronics, Computer, Automotive. (Pack of 6)

Features

• MULTIPLE CHARGING METHOD: This module is made for charging rechargeable battery/batteries using the constant-current/constant-voltage (CC/CV) charging method, charging port can take power from micro USB. The input has a MIRCO USB socket, which can be used to directly charge with the 5V mobile phone charger, and still retains the input voltage wiring solder joints, which can be very convenient DIY....Input voltage: 4.5~5.5V
• MULTIPLE PROTECTION'S: This module is used for single lithium ion / lipo / 18650 cell or multiple cell in parallel, this board have overcharge, over discharge and overcurrent protection; battery over-discharge protection voltage is 2.5V, battery over current protection current is 3A
• DRIVE LOAD: Connect the battery to the B+ B-, the indicator red light is being charged and the blue light to full, OUT+ and OUT- can be connected to the load, such as the booster converter module/buck converter module or other loads.
• ADJUSTABLE CHARGING CURRENT: The charge current can be modeled externally with the Rprog resistor R3......Default Output is 4.12V ~ 4.2V and 1AMP ....This can be connected with other robotics project or also or this work with other modules efficiently also like custom torch, flash light , solar cells, bluetooth, testers , wireless circuit, adaptors, buzzers, powerbank, camera, temperature sensor, audio circuit / headphone amplifier, bike mobile charger, ...etc
• Important: Please note that the battery terminal should be connected correctly to their respective terminal. The ammeter for testing current can only be connected in series with the 5V input terminal of the charging board. As Charging of AA, AAA and other rechargeble battery is different so, please check with battery manufacturing company manual *
