TLP recalibration error on Thinkpad X220

Error: cannot read charge level of battery BAT0

+

My attempt to recalibrate the battery on my X220 failed. Hunting for info I found this on github +

It's a TLP bug that was fixed a couple of weeks ago. The solution was to install the git versions of tlp.

+yay -S tlp-git tlp-rdw-git +

Now I can plug in my X220 to the mains and run tlp recalibrate BAT0 overnight.
