DUAL BATTERY CHARGING MADE EASY! The BEP battery distribution cluster is the optimum battery management system for your single engined Boat. The BEP Dual Charge Battery selector combines 1 of BEP’s 701S selector battery switches and a 140 Amp Digital Voltage sensitive relay (DVSR).

The 701S Battery Master Switch is the most compact selector switch on the market and offers a number of unique features. The highlight being the contour lock system, allowing it to be locked together with other switches and Digital Voltage sensitive relays. The 701S also features a removable rear cover insulating the rear terminals against any short circuits and ensures the switch meets ABYC requirements.

Digital VSRs offer the user a wide Range of switching voltages ensuring the open circuit Voltage is above the discharge Voltage of the exotic battery (AGM /Gel/Lithium) unlike that of the analogue. There is also an algorithm built into the digital relays which prevents unnecessary switching of the relay. The quiescent Current of the digital relays is 1mA which works out at about 1A per week.The digital unit also offers both uni and bidirectional charging. Most VSRs are set to bidirectional charging which allows the Voltage at either the input or the output stud to engage or disengage the relay.

The DVSR allows for two batteries to be charged at the same time. When the engine is started, and the start battery reaches 13.7 Volts, the relay closes, Combining the battery banks (start and house) and allowing them to be charged simultaneously. When the engine is stopped and the Voltage drops to 12.8 Volts, the relay will open separating the batteries.
