UPS-18650-Lite is a UPS power supply specially designed for Raspberry Pi model B series boards (namely 4B/3B+/3B, etc., hereinafter referred to as pi).It uses two standard flat-head 18650 lithium batteries for power supply. It support over-charge, over-discharge, over-current, short-circuit protection, support external power plug-in detection, support charging and discharging, when the external power is plugged in, the pi is powered by the external power source, when the external power source is unplugged, the pi seamlessly switches to the lithium battery power supply . UPS-18650-Lite is connected to the pi through 7 pogopins.The power supply and battery power measurement functions of the pi are all done through pogopins. The pi does not need to plug any power cords, just plug the external power cord into the UPS type-C port ,it can complete power supply and charging by the UPS. In addition, UPS-18650-Lite integrates the professional fuel gauge chip MAX17040G, which can be used to measure UPS battery voltage and battery remaining power.Charging current: Max 1A@5VOutput current: Instant Discharge [email protected], Continuous Discharge [email protected](PS: Please use good quality batteries and power adapters to ensure that the UPS works normally)Battery measurement: Percentage of battery SOC, an error +/- 2%,The measurement errors of battery voltages +/- 3mV(PS: The measurement error varies with the individual battery and the ambient temperature)Download link of the manual:https://www.adrive.com/public/rZ73mX/Instructions%20for%20UPS-18650-Lite.pdfColour: blackMaterial: ABS+metalPackage Contents:1 * Power Expansion BoardOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
