I've been doing this without problem.
In fact, I have a permanent external connection to plug-and-play the batteries in parallel every time it's not in use. Serves as standby (booster) to my already dual-batteries in the RV.
But, of course, my Renogy solar has a controlle and everything goes through it..
Ok, so you have not had a problem adding a lower charge battery added to the parallel bank? I have a Renogy Adventurer 30A controller. What size wires do you use for the connection and runs to the battery?
