KEHIPI UPS Module 3S (EN) Development Board

KEHIPI UPS Module 3S (EN)

The KEHIPI UPS Module 3S (EN) is a development board that provides uninterruptible power for single-board computers such as Raspberry Pi and Jetson Nano. It charges connected 3S lithium batteries while simultaneously delivering a regulated 5 V output at up to 5 A. An I2C interface allows real-time monitoring of battery voltage, current and power. Multiple protection circuits guard against over-charge, over-discharge, over-current, short-circuit and reverse polarity, and an equalising charge function improves cell balance.

Makers adding battery backup to robots

This module suits makers and engineers who need a compact UPS that can charge and supply power at the same time, with I2C telemetry for software monitoring. It is not for users who require an all-in-one kit with batteries included, nor for projects that demand a different output voltage or a higher current rating than 5 A. Buyers who need built-in wireless connectivity or a different battery chemistry should look at other solutions.

5 V at 5 A continuous from 3S cells

The onboard regulator delivers a steady 5 V at up to 5 A, which comfortably powers a Raspberry Pi or Jetson Nano plus typical peripherals. Headroom exists for short peaks, but sustained loads above 5 A will trigger the over-current protection and shut the output down. Runtime depends entirely on the capacity and condition of the user-supplied 3S battery pack; the module itself stores no energy.
