"Maxwell's 24-volt ESM enables our 6.7 liter diesel-equipped machines to successfully start at arctic temperatures, even with batteries that have been intentionally drained," said Charles Hedrick III, control systems and electrical engineer at Manitowoc Cranes, a major manufacturer of industrial cranes and a user of the 24-volt ESM. "By removing the batteries from the cranking equation, the ESM allows machines to provide stable power to sensitive electronics, preventing the problems that coincide with trying to start a machine with dead batteries."
