Linux Battery Charge Limiter Service

I have a project to control the battery but at the end of the day I needed something that just works. As I'm using auto-cpufreq I removed the TLP and therefore needed this battery limiter. Help planet and your pocket by preserving your laptop battery life.

Create the service

Create systemd service file (/etc/systemd/system/battery-threshold.service) to run as root:

sudo nano /etc/systemd/system/battery-threshold.service

Define component with default props:

interface IProps{
  propName:boolean;
}

export default function ComponentName(props?:IProps) {
  const {propName=false} = props?props:{}
}

Mikrotik log interface(ether1) traffic

This can be placed on an scheduler and logs your traffic like every hour or so.

{
:set $tx ([/interface get ether1 tx-byte]/1048576)
:set $rx ([/interface get ether1 rx-byte]/1048576)
:log debug "Traffic log,TX,$tx,RX,$rx;"
}

The log of script can be set to disk file for persistance
