    AJMRTC AA AAA lithium battery conversion module turns your original AA or AAA dry battery holder into a 1.5V power supply using 3V-4.2V lithium cells. The module steps down lithium voltage to a steady 1.5V during charging and discharging, perfectly simulating the voltage of ordinary dry batteries. It is widely used for modification of toys, remote controllers, wireless mice and other small electronic devices that originally use AA or AAA batteries. Small PCB size allows easy internal installation, and reliable voltage regulation safeguards your equipment against voltage spikes.
