Wiring up second battery

[nigeee2001]

Evening all
Additional leisure battery arrived today so hopefully be fitting to my La Strada tomorrow
Quick question
I realise that the feeds should come off different batteries so they are used / drained equally
So I'm guessing that my solar controller and inverter will be the same
So positives connected on one battery negatives from the other ?
Thanks for any replies to this - just want to he sure

Best way to balance the batteries is as below positive supply all in to one and negative connections all out of the other

Yes, you are correct OP.
If you have multiple items to connect after that , you can use bus bars, so all the pos attach to one and all the neg attach to the other, with each bus bar having a main lead connecting to the battery.

Making sure your varying cables are thick enough to withstand the amount of current

It's quite common to have an isolator switch and a big fuse very near the battery positive. You can take the feeds for the inverter, solar controller, loads, mains charger etc to the isolator or fuse.

On the negative side, if you are fitting a shunt resistor for a battery monitor, you'll want all the wires to connect to that. Then take a single wire to the negative battery terminal. If not, as suggested already, a busbar.
