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 equalizer 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. The equalizer is designed to save your batteries and the money you would spend replacing them. Users of the Vanner battery equalizers know that it is the most cost effective and dependable solution for dual voltage systems.

A typical system would include a 24VDC power source, such as an alternator, two 12 volt battery banks in series, and the battery equalizer. The equalizer connects to the 24 volt, 12 volt and ground terminals of the battery system. When the 12 volt loads require power, the equalizer ensures that the current is taken equally from both batteries, and that the voltages of the two batteries are kept equal. This equalization ensures extended battery life and provides a stable 12 volt supply for operating accessories.

Paralleling equalizers

Vanner Battery Equalizers may be operated in parallel to provide more power.

NOTE: The Vanner VANN-Guard Battery Equalizer is an extremely reliable device and, when installed according to the instructions, will provide reliable operation for an indefinite period of time. However, if a system abnormality should develop that would cause an equalizer malfunction, damage to the battery system could result if 12 volt loads are present.
