What is an Engine Start Module? An ESM works in tandem with batteries, extending usable life by providing reliable burst power at ignition. Ultracapacitors use an electrostatic field to store and deliver power. They charge and discharge in just fractions of a second, supplying rapid bursts of energy to crank the engine over. Reliable starts in any extreme, just what drivers count on.
