1675 also uses that charger, or one that looks very much like it. A few years back we took a dolly/handcart, bolted the charger to one (back) side, and welded pieces of aluminum for the on the other (front) for the batteries to slide into, angled a little less than 45 degrees from vertical. 3 rows, 2 batteries each. Anderson connectors on the ends color-coded to the diagnostic lights, and elastic straps to make sure the batteries stay in place while rolling. Can lay down or stand up (99% of the time ours is standing up), no balance problems because of the flat bottom of the cart being pushed steady by the batteries on that side.
