I’m tired of buying a new 12 V battery every 1-2 years. I have about 4 small (rated ~ 300 W [not VA]) UPSes with 7 Ah, 12 V, maintenance free batteries.
I’m thinking about replacing them with one, powerful unit. But the more powerful the unit, the more it costs - non-linear.
Do you have experience with some DIY solutions? Like 12V DC to 230V AC inverter, battery charger, some UPS controller (simple relay?)?
Or maybe you have some other idea that is cheap(ish)?
Where did you purchase? Camelcamelcamel shows those sub-$150 price drops on that capacity might be a couple years old, too. :-)
Well I did buy the last one a couple years ago so that tracks. CCC is absolutely the way to go though, it’s a must. I think I also grabbed one at Costco <$200 at one point.
I’ve picked up 1350s from Woot and Costco online.
I got mine from Costco, they go on sale once or twice a year there
