Active balancer use on lifepo4 minis?

[Johneb]

I saw a thread where someone was using an actove balancer on multiple lifepo4 minis in 4s for 48v to keep them balanced. I am planning on 4 minis in 4s for our 5th wheel. Does an active balancer make sense/work in this case?

Ha02 48v balancer

I use one on my agms. I notice small deviation without it.

I hear this makes a loud 12khz noise. Is this bothersome?

If you put it on a switch you could just balance every couple of days/weeks as needed to avoid the whining noise.

I was thinking of enclosing it in sound proof ceiling tiles.

Pretty sure it's that way with all the units and not a defect

If you say so

If it makes any noise i don't notice it over inverter fans

Edit. I just checked, it really doesn't make any noticeable buzzing sounds.
