A couple golf cart batteries would certainly give you more power longer. Make sure they are hooked up correctly and your house charging system is good to go with them.
Yeah, hard way to learn this but the lugs connecting to the posts are Red. The plastic covering for all the cables is Black. So take a pix of the top of the batteries before you start and after you take off the bunch of cables from the post, zip tie them together. Tape colored tape around the plastic covering for pos or negative ident, then go to the one next. Make sure each bunch of cables is zip tied to each other when removed and color coded taped on the plastic. And for those that missed doing that (me), peal the plastic covering back and the cables will be RED or Black for which cable is pos or neg. All this moving around with something heavy will probably trip the 100 A C/B just above the battery. When you are down there you might want to check the 50 amp C/B, the 5 amp fuse, the 250 amp fuse on the back wall and to the side of the hydraulic pump, is a 15 amp fuse as well. Check for loose connections in that area and put that battery preserver stuff on the terminals. Might as well check the pump resorvoir too and what I do is to remove it and lay it on a paper towel to see how high the fluid is on the stick. Can't see it otherwise. Those Coleman camp stoves are a good work bench here
