Today was the second day trying to use my diy reel system, it lasted 10 minutes before I had the batt symbol on the controller. Back to backpacks rest of day.
I have a 120ah battery fitted with a trickle charger to the engine, and run a 100psi shurflo pump from it.
I asked an auto elec I know to look and he says if I’m only doing short journeys, and turn engine off when working, that the battery doesn’t get enough time to charge, which is why it’s not working.
Any advice on this please?
