Thank you for your feedback!

Can I charge batteries that are connected in series?

Yes, the batteries can be charged without being disconnected with each other.

Connect a charge bank to each battery individually, as if the batteries are not connected to each other. Each charge bank works independently with only the battery it is connected to.

Will batteries connected in series finish charging at the same time?

If the batteries are in similar condition and charge level, you can expect they will charge at similar speeds.

If the batteries were completely discharged and neglected for a period of time, each battery may finish charging at different times.

My husband lives that he can hang it out of the way and just run the cords to the 2 units.
