Jrifedptry PD3.1 140W Power Bank DIY Module 2S/3S/4S/5S/6S Switchable IP2366 Bidirectional Boost Li-Battery Fast Charging Module Easy to Use,B1

The IP2366 bidirectional buck-boost module is mainly used to connect lithium batteries. The PD3.1 protocol supports a maximum fast charging output of 140w, that is, the maximum output parameter is 28V5A. There is a toggle switch on the circuit board, which can switch the battery voltage of different strings without loss.. Product usage: The product can be connected to a 2S/3S/4S/5S/6S lithium battery pack, with a 5.5 x 2.5mm DC connection port at the tail. The battery pack can be directly connected to the module after welding the DC cable. The method for switching battery packs of different strings is to toggle the battery voltage switches of different strings on the circuit board to achieve lossless switching.
