Uninterruptible Power Supply Module, Supports charging And Power output at the same time, 3S & 5V 5A Output

Waveshare 23884 - Uninterruptible Power Supply (UPS) Module, Supports Charging And Power Output At The Same Time, 3S & 5V 5A Output - UPS Module 3S (EN) This Uninterruptable Power Supply (UPS) module takes three 18650 lithium-ion batteries (not included) and offers a regulated 5V supply with up to 5A continuous output alongside a 3.3V output and a host of other useful features - perfect for the Raspberry Pi. The module supports simultaneous charging/discharging and can provide both a 5V and 3.3V stable voltage output. It also supports I2C output, allowing you to monitor and display the IP address, battery voltage, current, power, and other parameters via a terminal window. Onboard protection is in place too - overcharge/discharge, over-current, short circuit, and reverse polarity protection, along with an equalising charge feature. There are also battery warning LED indicators, letting you know if the batteries aren't connected correctly. In the box, you'll find the UPS module, UK 12.6V 2A power supply, and acrylic enclosure panels & fixings, as well as four XH2.54 squid cables: USB-C male, locking switch button, DC female (for power supply input), and XH2.54 Male. Note: This product includes a US power supply and does not include the required 18650 batteries. Assembly required (acrylic enclosure). Raspberry Pi is not included.
