Hi everybody, after using victron products now for over 12 years I now joined the community. I have got a question regarding the wiring in a 24 volt system made up from 6 x 12 volt 265 Ah batteries. I:would like to balance each pair of serial connected batteries but also all three banks of 24 volt. How many balancers do I need and how should I best do the wiring?Wishing a Merry Christmas to everybody!
Best wishes from Sweden

Further to @M.Lange perhaps also photo to inform the diagram.
I’m assuming it is 3 parallel banks of two batteries in series.
Please include the bus bars and midpoint connections in the diagram.
Probably Wort adding:I have set up with Bus bars and know the wiring with one balancer ... however, as I understand this set up only balances each bank of the serial connected batteries (or am I wrong) ... and I would like to balance both, banks and serial connected batteries ...
Do I need 4 Balancers?
Can you give us a simple wiring schematic of your system?
Thanks a lot for your swift reply! I can attach a wiring diagram tomorrow. So far some pictures below. The system is combined AC DC off grid. The DC load is an extra heating system. The wiring seems to look confusing, however, With this set up I have all data online. 4 mppt solar chargers are connected.
I believe that in this configuration you only need one battery balancer, certainly not four.
Does this match your setup (though it would appear you still need to add the midpoint links)?

Dear all, here comes now the simple wiring schematic of the battery part including the balancer set up as it is now. All wiring has the same length and the main cabling is all 90 mm2. As I understand with this I balance each bank itself but not the three banks. Any advice? I sense I need a fourth balancer ... - do I?
All the best from Sweden
@M.Lange and @warwick : wishing you a Merry Christmas as well

Hi everybody, I have done more research ;-) ... and found this: https://www.victronenergy.com/upload/documents/Wiring-Unlimited-EN.pdf Page 21 gives the answer .... As I now understand, with the three balancers in place I wouldn’t need the midpoint wiring. If I had only one balancer the midpoint wiring would be the answer. Is this correct?
Yes that looks right to me. I saw this in your very good diagram too. Makes perfect sense.
