Ideal for golf carts, personnel carriers, maintenance vehicles, scissors lifts, wheelchairs and any other 36 volt applications. Excellent for all marine applications as well. Each unit features a ferro-resonant transformer that compensates for input voltage variation. Current-limited in case of short circuits. All ferro-resonant units feature patented electronic timing for longer battery life, less water usage and fuller battery charges without over charging. These units are equiped with an output cord less the connector due to multiple use applications. ".
