🔋 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 Review

The battery works well but you can get similar performance with a smaller battery which I have also used. The lack of a charging circuit seems ridiculous to me. It seems to have good features for my needs. I probably wouldn't buy this product again and would prefer a smaller battery pack. Update: The output voltage doesn't seem to be as stable as it should be. My Raspberry Pi 3 shows a low voltage warning about half of the time it is running. CPU usage never went above 30%, but even at 0-5% CPU

Works great! It was very easy to assemble (less than 5 minutes) and surprisingly didn't add weight to the Pi as I expected. Now I just need to figure out how to reconnect my fan to it! A few pointers: do not insert the batteries according to the markings in the slots (it shows they are parallel, + top on either side), instead insert them according to the markings on the board itself (+ top and - top ). I didn't notice the other markings at first and thought my board was bad when it didn't turn…

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…

Please note that they come without batteries and do not indicate in the box where to order the correct ones. very expensive. When I received it, there were no instructions in the box. ZERO. I suspect it was an oversight by whoever packed it for shipping. The product itself seems to be quite well made and serves its purpose. Luckily, a colleague who recommended the product and already had it came to the rescue and provided the correct instructions.
