100,000s of units sold to the diy community you are going to see some
failures... wonder how many are self induced

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...

I have 60KW of EG4s and am seeing more and more posts of failing BMSs on
them. They are showing up on the LFP auction sites for $500 with failed
BMSs in higher and higher numbers. Making me nervous of my rack
reliability..

they would work fine at that voltage, but not 100% charged which is a good
thing. Regular power supplies cannot divert current like a DRS-480 for
example, so if your system goes to 0% and dies, when AC power is restored
the power supplies will need to charge the batteries and power your load at

LFP batteries need a special charger unless they are equipped with a
built-in BMS. Many, if not most 12V LFP batteries have a built-in BMS.

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
