I bought 2 of these for an indoor project they work well I expect with the load I put on them they will last a lifetime. just remember a 20 max output 10 amp charge and they do not have cold temp charge cutoff charging them in freezing temp could destroy them, and as far as value. over the past year prices have come down. Today I would buy a larger battery with higher capacity for the same cash I spent on 2 smaller ones, better current capacity and bigger batteries generally have better bms that includes low temp cutoff. I don't actually need low temp in my application but having it means it can be used for other projects down the road. since a modest load/charge cycle mean lifetimes that can span 20+ years.
