The Vanner VANN-Guard Battery Equalizer is an efficient and highly reliable method of obtaining a 12 volt DC power source from a 24 volt DC electrical system. The VANN-Guard makes the batteries look like they are in series and parallel at the same time. In addition to providing regulated 12 volt power, the system ensures that battery voltages remain equal which significantly extends battery life.
Ultra capacitors improve the reliability of a vehicle’s starting and electrical systems. Used in parallel with a vehicle’s batteries, the StartSentry assists a starting battery on every start. It can also be configured to remove transient stresses from a vehicle's electrical system and therefore improve battery life with potential fuel savings.
