Limit Battery charging on Laptop ?

I have a Lenovo Ideapad Flex 5i running a 10th gen Intel i5, I tried using TLP to set the battery charging limit to 80 but it always went over 80, but I did this using the TLPUI, where it mentioned that it was for Thinkpads, but I assumed that it should work in general. Is there any way to limit battery charging at all ?

check

cat /sys/class/power_supply/BAT0/charge_start_threshold

and

cat /sys/class/power_supply/BAT0/charge_stop_threshold

i.e.

echo 45 > /sys/class/power_supply/BAT0/charge_start_threshold
echo 75 > /sys/class/power_supply/BAT0/charge_stop_threshold

Hi, thanks for replying ! when I ran, " cat /sys/class/power_supply/BAT0/charge_start_threshold" it turned "cat: /sys/class/power_supply/BAT0/charge_start_threshold: No such file or directory"

Also when I did "echo 45 > /sys/class/power_supply/BAT0/charge_start_threshold" in sudo, it said "bash: /sys/class/power_supply/BAT0/charge_start_threshold: Permission denied "

Do you have a setting in your BIOS/UEFI to do that? That's how I limit my battery on Pop.

Unfortunately I don't see any settings in the BIOS/UEFI for it, previously when I ran windows 11, I was able to do it with Lenovo Vantage which was a windows only software, Windows 11 was really slow and laggy so that was why I switched out of it.
