My previous team had a battery cart that was small and compact. It held the batteries horizontally in 2 columns of four batteries each. It looked like a tiny little bookcase with tiny little shelves. It was about 24" wide, 20" tall, 16" deep (I'm guessing from memory here). Each "shelf" was about 4" tall, 9" wide, and 10" deep, e.g. the footprint of a battery laying on its side. Two four-bank NOCO G4 chargers sat on the top of the cabinet so you could access the controls.

It was a squat, stout little thing. You could roll it under a table. The disadvantage of this setup is that it is very heavy. Also, the NOCO G4 only charges at 1.1 amps so it was a little slow.
