First pic is in the box.

Second pic is hooked to five batteries. Will report when / if done charging.

The four huge batteries in the back row are out of a couple of floor scrubbers I purchased at a surplus sale. OTHER THAN dead batteries, they both work fine; just need a few maintenance items.

I can probably get away with much smaller batteries, but if I can get these to work, all the better. The black ones (Duracell) cost about $320 each, the brown ones (Trojan) cost $410 each; so figured it was worth the gamble. There is no "magic" to either one, so could buy the cheaper ones, but would rather not. I could also go with a couple of Optima yellow top, and save some money. These are designed to clean up to 92000 square feet on a single charge. I won't ever clean over 2900 feet at a time.
