Lots of folks run their battery's dead & i didn't want to deal with ithat which is why I built a ammo can battery box for a 19 amp hour lithium nmc battery from amped outdoors & put a cutoff switch in it. The gls-10 & 93 sv are also on their own plugs that i attached sae connectors to to be able to unplug them when needed. I also installed an sae connector on the oppisite end to plug the charger into. Pretty foolproof actually & works great & can also be used for other things if needed.
