Dc change over switch

Dear team

I recently installed my easysolar gx and it seems to be doing well and excited. I have two 25.6v 200mph victron batteries connected in 48v system they are not enough for my loads. I recently bought 4 12v 100amph victron batteries from a friend. I know it is not a good idea mixing batteries of different capacities but I need to use the two sets. I there any DC change over switch that can automatically switch to different battery banks depending on soc

Not an automated one to my knowledge.

There are isolators.

It is more complicated that that though, if you depleted the agm bank you want it to charge asap. Cant leave it in that state and switch back to the other bank. You would need to think about situations like that.

If your existing batteries are AGM, you could connect two strings in parallel. Far from ideal, will lead to uneven load distribution, but should work until you need to replace all the batteries.

Will it damage batteries? I don't know.
