I wouldn't use a home made battery in a production site. _Every_ LFP
battery I look at has a bms. They are getting almost cheaper to buy
with a bms than you can source new cells for without unless you go to
the auction sites...

LFP batteries need a special charger unless they are equipped with a

While I have used, read about, studied, and debated about LFP
batteries, one thing I cannot find an answer to:
Is there a problem with using a regular voltage supply set to 13.4
volts ( 90% ) charge to maintain a LFP battery for backup power
use? Is there a need to buy a specialized battery charger like a
samlex to charge an LFP battery?
Note that I am currently using regular power supplies to maintain a
bank of LFPs. I just don't know if I am setting up for an issue in
the future...
Self heating 12v batteries have reached a new low with one just
becoming available on Amazon for $229 and, with a netonix, that would
be a pretty simple system.
