Frequently Asked Questions
Q: What type of battery does this UPS power module use?
A: This UPS charging board is designed for a 3S LiPo 18650 battery pack (11.1V nominal). The module charges the battery to a full 12.6V and cuts off power at 10.5V to protect the cells from deep discharge. Note that batteries are not included.
Q: Can I power multiple devices at the same time with this board?
A: Yes. The module features four independent output channels — two at 12V/1.5A, one at 9V/2A, and one at 5V/2A — allowing you to run multiple devices simultaneously, such as a router, microcontroller, and peripheral, all from a single board.
Q: How quickly does the module switch to battery power during an outage?
A: The board uses automatic battery power switching with fully surface-mount components, enabling a near-instant failover so connected devices experience minimal to no interruption during a power failure — ideal for always-on applications like network equipment or monitoring systems.
Q: What protections are built into this UPS module?
A: The module includes short-circuit protection, high voltage (overvoltage) protection, reverse polarity protection, and output overvoltage protection, making it safe and resilient for a wide range of DIY electronics projects.
