Helios Ess – Sol-Ark 15K Conduit Box Discover Energy (No Cables)

a lot of batteries claim to be outdoor rated but you can tell theyre kinda pushing it. this one is legit. seals are solid, enclosure is thick, and ive had it sitting outside through rain wind and already some hot days and zero problems. 314ah capacity is excellent. charges up quick with my array and runs my house all night easy. discover energy makes a quality product
