My bank consists of a d3400 under the hood an xp3000 x2500 and a north star g31 I've had them in the car for at least four years that why I'm thinking that this could be good for them. Doing them separately would take me a lot of time because of battery location.

Hi my question is can the recovery mode be used on a small battery bank of mix groups or should they be charged seperatly?
