Hi,
I'm connecting up an IP22 Smart Charger (30A model) to charge two 110Ah leisure batteries that are connected in parallel but was unsure what wire size to use. I have some 30A rated wire here, and thought it may be suitable given (as far as I'm aware) the max output from the charger is 30A, but I wanted to be sure - still learning as I go.
So in short, what size wire would you recommend? The batteries are less than 1 metre from the charger also.
Thanks,
Ryan
Hi you can use the “victron ToolKit” app
It Will provide you with all information

In addition to the above toolkit, take a look at the draft Victron document "wiring unlimited" - do a search for it on this Community. It'll give you a bit more context about DC wiring (esp section 4).
I find that generally speaking I use larger diameters than is necessary for current capacity, because I want to limit the voltage drop. The calculator should tell you the size required for a given voltage drop.
