Victron BMV-712 Install Question

A lot of this depends on just how you are running the wires and exactly what is in your trailer. If you have a 1000W inverter and run it at full load, you can get up above 100A in some cases. If you have a single wire from the battery(s) and want to stay inside NEC guidelines and have low temperature insulation (yes that's a lot of qualifiers) a piece of 1/0 would be what you would need. With high temperature insulation (and surroundings) a piece of number 4 might be fine. Double up the wires (one from each battery) and number 4 is likely ok no matter what (yes the unequal length stuff gets into it on two cables ...).

So, exactly what is in your trailer?

Two Lifeline GPL-24T AGM batteries

Wildkat PD 4655 55 amp converter.

For now I'll just tie the batteries together outside the AS and use the one stock inlet from the original set up.

May not have time to do the Victron for a few more weeks.

My "problem" is no where to really work on it as it's in storage. I can get some work done like basic batteries and interior but getting really involved will have to wait a few months.

Thanks,

Warren

Since you didn't ask, I will not mention that not all my battery cables are identical . The pair on the tongue and the pair under the sofa are wired slightly differently.

Well...if it isn't a big concern for Bob#1, I'am certainly NOT going to fret over it. 😂

Hi

Ok, so no inverter and no other big loads worth mentioning on the trailer. Why get a second battery?
