2S IP2326 Lithium Battery Charging Circuit

2S IP2326 Lithium Battery Charging Circuit 1.5A 15W

3S Li-ion Type-C USB Input 8.4V Battery Accumulator 18650 QC Fast Charge Balance Powerbank Power Supply

You must charge your batteries with the current they need. Charging the battery with high current reduces the number of battery charge cycles. If you do not know the battery charge current; levels such as 2/10  3/10 of the battery capacity are the normal charge current.

In case soldering is done, the right of return is void because of the physical change. Before soldering you can quickly understand with a multimeter that the product works.

     It is a 2 cell lithium battery charging circuit using the IP2326 integrated circuit. It has a Type C supply input socket. There are 2 solderable pads on the sides of the usb socket for external voltage. It has 1.5A charge current and at most 15W power support. Using adapters with fast charge support as the source increases the charging efficiency. The input voltage is boosted and used in the battery charging process. 

     It comes from the factory able to charge 2S batteries. If the 2 pads located near the B- connection pad on the product are short circuited and the resistor next to them is removed, the board can also give 3S battery charging support. It has no BMS function. It is suitable to use it with a BMS for battery over discharge protection. The red power led shows that the product works. The blue charge led shows the charging status. Blinking means charging continues, if it is not lit it means charging has finished. With the Ntc temperature sensor connection it can monitor the battery temperature status.

Warnings:

•      When the product reaches you, power should be connected through the type c usb port and the battery output voltage should be measured with a multimeter. Products whose integrated circuit is damaged or short circuited will be evaluated as user error.
•      Incorrect battery connection can damage the product. The connection must always be made by checking the battery polarity.
•      The cables must be thick enough to carry at least dc 12V 2A current.
