I had to replace my UPSs a few weeks ago on short notice due to hardware failure, and I ended up getting a few LiFePO4 ones as a stopgap since they were on sale and I'd always wanted to try them. So far, so good. Curious if anyone else has switch to lithium UPSs from lead-acid and how that's going for you.

I have a big 20Ah, 48v e-bike battery that I've used with a sine-wave inverter for standby power, and it's a bit over 11 years old and going strong. So, as far as the batteries in these are concerned, I am cautiously optimistic that they'll last close to the 10 years they're advertised as. The electronics and inverter...we'll see, I guess.

Bonus question: While we're on the subject, has anybody tried those drop-in replacement 12V LiFePO4 batteries for regular UPS's? Supposedly, it says the BMS in them can work with the lead-acid chargers in UPSs and safely charge them, but I'm not sure I trust that.

GoldenMate is the brand

I am in need of replacement batteries and a couple of new UPSes, mostly just due to age and failure too.

A quick google and I mean, they look entirely reasonable and priced on-par with more traditional ones.

Probably going to pick one up, thanks for surfacing a thing I did not know existed.
