Review on 🔋 SunFounder Power Supply Module for Raspberry Pi UPS with Rechargeable 5V/3A Lithium Battery Pack Expansion Board, Compatible with Raspberry Pi 4B 3B+ 3B/2B and 1 Model B+, Battery Not Included by Olubanjo Triantafilou

Worked fine at first but I left it charged overnight (battery packs 3.7v 18650 as required by the station) and now there is no battery charge. For this reason I bought a kit with a charging function. It originally had a current remaining life indicator, but no longer shows battery status, just board status with a single blinking LED at the top. This specific indicator is not listed in the Guide as to its meaning. The battery itself is still going through the PI just fine, so the problem seems to be with the part that is supposed to charge the batteries. Edit: Continued attempt to use this thing damaged 3 batteries in total, even with an entirely separate charger. I could just take one as EoL and go bad, but 3 in the short term is too much of a coincidence. I will not buy anything from Sunfounder again if I can.
