Solar setup upgrade – need a 200AH deep cycle for my off-grid weekend plans

I've finally taken the plunge and built myself a small solar setup at my weekend farmhouse, nothing too crazy just a few panels and an inverter to keep the lights on and run a small fridge when I'm out there, but I quickly realized my old car battery was absolutely not cut out for this kind of deep discharge cycling. I've been looking into proper deep cycle batteries and it seems like 200AH is the sweet spot for what I need, but the more I research the more confused I get about all the different types – there's flooded lead acid, AGM, gel, and now lithium is getting more affordable too. I'm leaning towards AGM because I've heard they're maintenance-free and handle partial charging better than the traditional flooded ones, plus I don't have to worry about topping up water levels which is a huge convenience since I'm only at the property on weekends. The only problem is the weight because these things are absolutely massive and I need to figure out if my battery box can actually support that kind of heft without collapsing. I also need to think about ventilation because the space is pretty tight and I don't want any hydrogen gas buildup causing problems while I'm sleeping nearby. A buddy of mine who does a lot of camping recommended I look into a service that specializes in larger batteries since they'd know how to handle the installation properly and make sure the cables and fuses are all rated correctly for the higher current draw. I work in Business Bay during the week so I'm thinking maybe I can find something around there and get it sorted during my lunch break, maybe even find a place that does Elite 200AH Battery Replacement Business Bay since it would save me a trip across town after work. Has anyone here set up a similar solar system and found that the 200AH was enough for a weekend, or did you end up wishing you'd gone even bigger? Also, any tips on what brand to look for would be massively appreciated because I want something that'll last at least a few years without giving me grief.
