FYI Looking at house battery volts - Digilevel vs. Magnum Inverter Controller

[Kevin D Pem]

There are TWO "BMS"'s on my setup (Magnum BMK paired to the inverter) and a separate Victron BMV-712 paired into the Victron stack of MPPT and Venus GX. The picture is showing under load such as a hot pot boiling water or a Keurig starting up. This is not stabilized voltage and why I ran my LBCO down to avoid complete shutdowns from a single spike below my setting. I use 11.0 but Newmar recommends 11.9 which should be 50% discharge of your batteries. Again, there are horrendous spikes depending on the demand is not the actual voltage of the 900 aH battery bank, just an instantaneous load.

What is that about 500# in lead, nice ?

I'm replacing my 7 year old wet cell Interstate batteries with Trojan 105-AGM's . The data sheet show that 11.64 Volts is considered 0% state of charge. 12.84V is 100%.

Yah @Buly mine don't say, I just go by the old standard set by the battery standards many years ago. This is all my batteries say.
