I think for those playing games. If you want to stop it trying to charge the battery.
I think the best work around is to set:
ectool chargecurrentlimit 0
It will prevent it trying to charge the battery at all.
Set it back to normal behavior with:
ectool chargecurrentlimit 10000
The 10000 is an arbitrary value. It just needs to be above what the battery “Desired current” is likely to be.
The battery “desired current” overrides the “chargecurrentlimit” if chargecurrentlimit > Desired current.
The battery “desired current” is overridden by “chargecurrentlimit” if chargecurrentlimit < Desired current.
