These are a really handy module for charging 2S, 3S or 4S battery packs from a USB power supply. They will draw 4A, so please ensure that your USB power will supply is rated to at least 4A / 20W and it is best to use as short a cable as possible.
They should be used in conjunction with a suitable BMS (Balanced Charger), We stock a wide range, use the links above to find one suitable for your project.
