i recently bought a 1987 chevy g20 from someone that was converted by the Okanagan company years ago. the previous owners had an Interstate SRM-27 battery already put in it and told me that i’d have to plug it into a regular outlet somewhere to recharge it. does this mean their setup was just running off one battery with no system to recharge it, not even from the alternator?
i’m trying to switch it out to either an AGM battery or a lithium battery but i can’t figure out their setup and don’t know what i already have/what i will need. i’ll include a picture of the battery, i see there’s wires attached but they run underneath the wall boards so i can’t tell where they lead exactly. im going to be living in my van full time at a camp with shore power. the side of my van has a built-in retractable cord for the electricity but i’m confused if that would charge the battery? hopefully this all makes sense, thanks in advance! #lifestyle source
