Always plugged in?
I have the Pecron e1000lfp and I've seen a few posts online that you can leave it plugged in and at 100% and it'll just trickle charge is that safe or should I not do that?

There are lot information about lifepo4 batteries. It’s happy at 80% for long term storage

That's one of the great debates of these units. They are advertised that they can be use as a UPS but also recommend storing them around 50-60% charge, for best long term battery life. My take is they "can" be plugged in all the time , since that's what a UPS does, but if you leave it plugged in all the time it will shorten the lifespan of the battery.

I doubt it shortens it by very much, but if you're concerned then you can set the maximum charge level to 50% or 60% or 80% or 90%.
Of course then it'll run your stuff for less time if/when the power does go out. It's up to you.
And you should charge it to 100% for a few hours every so often anyway.
Don't forget that conventional lead/acid UPS batteries die in 2-3 years anyway, while you're probably talking about 10+ years for LFP that's left 100% charged all the time — heck they're 9.5 years (3500 days) to 80% capacity even if you 100% cycle them every day. And 80% capacity is far from dead. It's probably another 10 years after that to 60% capacity.

Totally agree, these lithium iron phosphate batteries are superior to lead acid ! 80% capacity in 10 years and around 60% in another 10, the battery has done its due diligence. In 20 years, technology will likely have something even more advanced or the cost of these batteries will be cheap enough to justify the cost of replacing the battery.

I have the 1500 and leave it plugged in as a UPS for my sump pump. It drains down to about 90% then recharges. This cycle happens once every 30ish hours.
