BestGo 12v 400amp battery trouble…continued

[Roamingkat]

I was using Katie33kate…but cannot get it to let me change password. Anyway..new profile name but the same ole me.

so, to update this…I finally got a replacement battery from seller. Another BestGo. AND..same problem!!!!!!!
good grief. Now when I get to 14.0 it is the battery #4 that is overcharging (previous battery is was #2). But same exact issue.
seller is claiming it is my configuration causing this. What? Ok..maybe I don’t understand. I have done some research online, I cannot find anywhere that would suggest that a configuration could cause a balanced battery system to be out of balance on one battery.
this battery is completely built with daly BMS wired and attached …all in one case with batteries unreachable without disconnecting BMS, plates and wiring….obviously I did not do that.

I have 2 450w solar panels handled by victron 150/85. I have a second victron 150/70 which handles 4- 100w panels (but this system hasn’t been turned on in quite a while). Also a Renogy 2000w inverter/charger. Is it possible this is the problem? I haven’t found any info on it…but, maybe?

is it possible that Daly BMS cannot handle the large amps my MPPT throws at it?

Having trouble with new BestGo 12v 400amp LiFePo4

This is a long story. But..I bought the above mention battery. It has the built in BMS and blue tooth. I love being able to see what is going on with this. first time I tried to fully charge (on my system it is 14.2) I got a fault alarm at 14.0. The blue tooth shows battery 4...
