what player describes is balanced 'if you only have 2 batteries, then simply linking them together and taking the main feeds from diagonally opposite corners cannot be improved upon.' ' we keep getting asked where the chargers should be connected to. We didn't address this question because it seemed so blatantly obvious where they should be connected that it never occurred to us that anyone might be unsure. The chargers should always be connected to the same points as the loads. Without exception. ' www.smartgauge.co.uk/batt_con.html

I was thinking about the commander too , but its way more expensive then the rover. How do you have your batteries connected? I read somewhere that all the connections should be placed on one battery(1st battery) (example charge controller cables, inverter cables) and not on the second battery you paralleled onto the 1st or does it not matter? They are connected to the ends of the run of the batteries.... The Neg of the first battery and the Pos of the last battery....
That's what I've read and seen and it makes sense as if you hook everything to the last or the first battery, The draw down and the charging would start there....

LOL Your kidding right?
I wouldn't believe anything that anyone said that twisted wires on the ends of 6 wire lugs the way he did and then said you need to cover them up so they wouldn't get wet? LOL That's the dumbest thing I've seen in a while....

I guess you are right.
So like this? for parallel, the charge controller positive is connected to the first battery and the negative is connected to the last battery ? And the same of the inverter?

Yep hook them to the same terminals... CC and the inverter...... Pos and Neg....
Also twice a year unhook all of your wires and clean the terminals on your batteries... Flooded or sealed a clean terminal will conduct current much better than a corroded one....
How long do you think that guys twisted wires would work before they stopped working?? Not very long I'm sure.....

LOL, i hope for his sake, very long ... How long are your inverter cables and what gauge? I need longer cables when i hook up the second battery, i was thinking 3ft, 4 AWG. Because now i got 4 AWG (1ft - fuse - 1ft) positive , and 2ft negative, to maintain the exact length for the pos and neg. For the added battery, i was thinking 4 AWG (1ft - fuse - 2ft) positive and 3ft for negative. What do you think ? if 4AWG think enough?

Also what do you recommend for the battery interconnect cables? i was thinking 2/0 2ft as these are big batteries and they will be placed next to each other. Is the length too long?

My entire system is very close to each other.... Well other than my panels and they are about 15ft away from the CC..... I don't remember the exact size of my cables are but I think they are 4AWG..... All my battery related cables are the same gauge...
You don't need those fuses between the batteries.....

That length is just fine I wouldn't make them any longer than is needed......But you will need to have a small arch in the cable just in case you need to get between them for some reason.... 4AWG will work just fine for that short of a distance.... Bigger is always better but 4AWG is easier to work with...

Here's a pic for 2 12's. I used 1/0 welding cable for all my battery interconnects and to the first fuse for pos & bus bar for neg. If you use a fine cable like that don't solder the lug on or you'll end up with a thick copper bar Attachments:

And like I said the bigger the wire the better...

Wow , point made perfectly. I now know how to connect them.
