I'm not that familiar with power settings on Fedora (having F26 here).
But a look at upower.service might be useful - mine is disabled:
% systemctl status upower.service
● upower.service - Daemon for power management

'Suspend' doesn't seem to be supported as an action for low battery
level on Gnome ...
But here, on F26: in
/etc/UPower/UPower.conf
I have a config option to set action (again: no suspend) according to
a battery percentage level. Excerpt:
----------------------------------------
UsePercentageForPolicy=true
# When UsePercentageForPolicy is true, the levels at which UPower will
# consider the battery low, critical, or take action for the critical
# battery level.
#
# This will also be used for batteries which don't have time information
# such as that of peripherals.
#
# If any value is invalid, or not in descending order, the defaults
# will be used.
#
# Defaults:
# PercentageLow=10
# PercentageCritical=3
# PercentageAction=2
PercentageLow=10
PercentageCritical=3
PercentageAction=2
----------------------------------------
Trying 'upower -d' here results in the display of current power
settings ...
HTH,
Wolfgang
