suggestion regarding Parasitic drain from Aux lights:
Do not leave the Aux On 24/7, instead unscrew the head when the light is not in use, so the Aux wont drain the battery so fast.
or, Program the Aux to turn Off when the light is locked.
I dont remember how many days it takes to drain the battery if Aux are On 24/7… maybe someone has that info handy… I think it was about 13 days, needs confirmation.
