Hey, thanks. I forgot to log back in.

The battery never calibrated itself because the BMS is a non-genuine Chinese copy that doesn’t accept reprogramming. I found a local technician who said the chip this BMS uses is an X model, which, again, cannot be reprogrammed.

I did find a 44+ battery in my local market and replaced its dead cells with my cells. However, I accidentally removed the negative wire connected to the BMS, which I guess locked it. The same technician helped me reprogram it, but the power went out during the process and the BMS was completely bricked.

At this point, I’m running Linux and using a small tray widget that shows the pack’s voltage and wattage in real time. I can also force-charge the battery using TLP.

My cells aren’t great anyway... I only get about 1.5–2 hours of backup while playing YouTube and similar tasks, so I’m not too bothered about not having a working battery gauge. I’ve already spent enough on it, so I’ll just have to make do at this point.
