Dual battery charging made easy! These distribution clusters are the optimum battery management system. Featuring dedicated battery switches for each bank and a Voltage Sensitive Relay (VSR). The VSR allows for two or more batteries to be charged via the engine charging system. When the start battery reaches 13.7V the relay closes allowing the house battery to be charged. When the engine is stopped and the voltage drops to 12.8V the relay opens, isolating the start from the house battery. This prevents accidental draining of the start battery and protects sensitive electrical equipment from harmful engine start up spikes. Available for single and twin engine outboard boats with engine charging systems up to 100A. Clusters come completely bused and are easy to install. An ideal replacement for battery selector switches.
