TLP Charge Threshold Configuration on Lenovo IdeaPad

Kubuntu 23.04
Lenovo IdeaPad (not ThinkPad) 3 15ALC6

Hey, I'm trying to configure TLP to start charging when the battery reaches 50% and stop when it reaches 80%. I just want to make sure I'm doing everything correctly. Here's the comment in the tlp.conf file:

# Battery Care -- Charge thresholds
# Charging starts when the charge level is below the START_CHARGE_THRESH value
# when the charger is connected. It stops when the STOP_CHARGE_THRESH value is
# reached.
# Required hardware: Lenovo ThinkPads and select other laptop brands are driven
# via specific plugins, the actual support status is shown by tlp-stat -b.
# For more explanations and vendor specific details refer to
#   https://linrunner.de/tlp/settings/battery.html
# Notes:
# - ThinkPads may require external kernel module(s), refer to the output of
#   tlp-stat -b
# - Vendor specific parameter value ranges are shown by tlp-stat -b
# - If your hardware supports a start *and* a stop threshold, you must
#   specify both, otherwise TLP will refuse to apply the single threshold
# - If your hardware supports only a stop threshold, set the start value to 0

The thing is, it's not very clear for me whether my device supports "a start *and* a stop threshold."

Here's the output of tlp-stat -b:
