So currently I run 3 x 100amp lithium batteries, not cheap items at £480 each
, but I was aware of that.
So one battery has decided to die.
That’s the reason I have 3 and not one battery of 300amp.
Tbh, I’ve not been keeping an eye on the BMS of all three batteries, recently, as all been fine, but early one morning the mppt started to flash, the roof vent maxxair started to make intermittent noise ( like a dying smoke alarm but more rapid).
So battery no2 is dead, no signal, ( Wi-Fi) . Lucky I bought them locally to where I live, and the seller happily will honour the guarantee.
But it’s just to say, failures happen, have a back up( in this case two other batteries).
Incidentally, perameters had been set to shut down on over/ under voltage protection….see what happens
.
