AJMRTC TEC4056 lithium battery charging module is a non-protection charging board for single 3.7V lithium-ion batteries, with 4.2V full charge cutoff. It works under constant current and constant voltage charging logic. This board only realizes charging management and does not contain battery overcharge, over-discharge protection circuit, so it must be matched with lithium cells with built-in protection board. The charging current can be modified by replacing the current-setting resistors. The onboard LED indicators show charging and full-charge status clearly. Small PCB footprint, simple wiring. Widely used for electronic hobbyists to build portable power supplies, small lighting equipment and other DIY electronic projects.
