A jump pack does not have enough long term power for what I need, so I'm thinking of starting with one of these since it has a charge indicator, battery connect posts and 12V plug already installed:
adding one of these:
and wiring it up as needed with a 6m run of cabling with anderson plugs on either end.
My primary use for this will be to sit next to my Engel MT45 for extended outings without worrying about killing my starting battery. I'll be putting an Optima Dual Purpose in the box and will top it off as needed with my Sunsei solar panel which worked very well last season.
The plus to this setup will be ease of use in multiple vehicles, quick connect/disconnect, flexibility in location of battery and the ability to keep it charged up while underway.
Any thoughts or tips on wiring this up?
My initial thought is to run a pair of 4ga wires from the battery to the back of the vehicle, terminate with the female Anderson plug, add a male Anderson to the battery box and add the ACR and an inline fuse under the lid of the box.
