Power switching for uninterrupted operation The Lithium Battery Boost Charging Module integrates a UPS (Uninterruptible Power Supply) circuit that automatically switches between external power and battery power, ensuring continuous operation without gaps. UPS power supply efficiency When AC power is available, the UPS routes power from the external source to the load through an efficient boost circuit, reducing energy loss and improving overall system efficiency. Flexible interfaces and broad compatibility Two versatile battery sockets support a wide range of lithiumion batteries. A universal Micro USB charging port allows easy recharging from various power sources, and a direct DC5V input provides an alternative charging and power method. Clear status indication and safe charging An LED indicator communicates the charging status at all times. A solid green light indicates a fully charged battery, and charging stops automatically to conserve energy and prevent overcharging. Key benefits Maintains operation during power fluctuations or outages Efficient power routing to minimize energy loss Flexible charging options and broad battery compatibility Simple monitoring with automatic, safe charging Use scenarios Small electronics projects or prototypes that require continuous uptime during power flickers Portable or offgrid setups that can be charged via USB or DC5V and need seamless power switching Remote sensor stations or equipment that rely on external power when available and battery backup otherwise
