Here is a link to the product page. http://www.autometer.com/6-station-a...-115v-agm.html

We also created a battery cart designed specifically for this charger with the charger mounted vertically. The cart hold 10 batteries (6 charging and 4 storage) and has wheels for easy transportation to events

Have you found that having 6 chargers available is enough? We have been running 6 of the KOP chargers for a few years with 3 batteries in backup and there have been times when the oldest battery on the charger was not fully charged when needed.
