Is it possible to charge two 12V batteries wired in parallel

Hello guys,


I got a question for you: I have an installation in a camper van with two 100ah 12V batteries (which gives me 200ah 12V as they are wired in parallel), and using a Victron IP22 to charge them. So far I charge them individually, but I would like to know if it is possible to charge them at the same time.


On this product page (https://www.photonicuniverse.com/en/catalog/full/525-Victron-30A-12V-Blue-Smart-IP22-mains-battery-charger-with-Bluetooth-connectivity.html) it says that "This unit is able to charge either a single 12V battery, or several 12V batteries connected in parallel (batteries must be the same type, capacity and age)." Which is exactly what I need :) The question is how to wire the charger properly.


Thank you !

Nicolas

Yes, you can wire two in parallel.
Be sure to wire them as in the diagram below to ensure an equal charge on both batteries.
