TP4056 1A Li-ion lithium Battery Charging Module – Mini USB Pack of 2

About this item:-

• 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
• 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
• 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 module / robotics project or also or this work with other modules efficiently also like custom torch, light , solar cells, bluetooth, testers , wireless circuit, adaptors, buzzers, powerbank, camera, temperature sensor, audio circuit / headphone amplifier …etc.
• 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.
• 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
