I have this HAT: https://www.cytron.io/p-raspberry-pi-u1 ... uous-power with Panasonic NCR18650B, I use it with a RPi 4 2GB with a Meanwell LRS-35-5 PSU (5Vdc 7A).
Here is the led blinking description:
- LED1-LED4 indicates the remaining battery capacity.
- LED5 indicates the current power supply and charging status; when U100 is outputting, the LED5 is always on, and will flash quickly if it is charging; when U100 is not outputting, LED5 will flash slowly if it is charging, otherwise, LED5 will be off.
I have two U100 boards and I have similar issues, so I think it is either the board description that is erroneous or the battery have an issue ?
Anyone ever used that HAT or have an idea about what's going on ?
I tried also to increase the PSU wire size to 14AWG so I should be fine, voltage is at 5.1Vdc.
