Description

Pi-UpTime UPS 2.0 is designed to work with a Pi-4 or a Pi-3. Power is input via USB-C OR micro-USB connector. Max 2.5A. Can use Li-Ion (Li-Polymer) or Li-Phosphate batteries. An On/Off switch connection allows power to be cut off to the Pi or reset the Pi as needed. An on-board ADC measure operating conditions (Vin, Vout, Vbattery and Temperature). Shutdown can be triggered when battery V is low. Python script is available for download from the Alchemy Power web site. External connections via terminal blocks allow alternate connections for Vin, Vout, and Battery. UPS 3.3V (max 800mA) allows connections for external sensors. I2C bus connection to the Pi is also available for external sensors. No GPIO's used. Includes BMS and several safety features (temperature, low battery charging, current loops between batteries, max 2.5A current limit etc. Battery, terminal blocks, switches not included.
