VCC(MAX) is the maximum supply voltage . However you can change this by changing the 1kresistor next to the IN- pad the bottom-left of the board. It is fine to leave it connected to a battery for. The boards needs a 5V power supply.

The current resistor can be replaces for other charge.

This tiny module is perfect for charging single cell 3. With Mini-USB on board connector, you can directly connect to computer USB port for battery charging. The module cuts off charging current when . For less than £you can. There are additional modes as per the embedded features in the IC. These modes can be observed from the following graph taken from the datasheet.

Lithium Polymer (LiPo) battery is a type of rechargeable battery that provides high energy storage to weight ratios in an eternal variety of shapes and sizes. LiPo batteries has taken the electric RC gizmos world by storm,especially for Radio-Controlled (RC) toys like electric helicopters, airplanes and boats. I did a comparison of the programming resistor vs charge current info from the datasheet , and my empirical data seems reasonable. Input Voltage Operating Range: 4. We need to do only two things, give a voltage in the range of 4. Next, we will build our rest . The Information contained herein is supplied as a service to our customers and accuracy is not guaranteed nor is it definitive of any particular part or manufacturer.

Use of information and suitability for any application is at users own discretion and user assumes all risk. The CV voltage is slightly below 4. I added a temperature measurement to the test this time, as can be seen the chip heats up fast and then . Integrated System Load Sharing and Battery. Simultaneously Power the System and.

Voltage Proportional Current Control (VPCC) ensures system load has priority over Li-Ion battery charge current. Low-Loss Power-Path Management with. Charge the Li-Ion Battery. This module takes 5V from a USB mini B cable (or hard wired) and intelligently charges and floats a single 3.

Luckily, it is pretty easy to modify the board to charge lower capacity batteries.
