BEP 714-140A DVSR Single Engine Dual Bank 140A

The 714-140A-DVSR uses a dual-sensing DVSR (710-140A). This system ensures you always have a fully charged spare battery available. When the switch is in the first position, the first battery becomes the sensing battery for the VSR. The isolated second battery is charged through the VSR to ensure it's always fully charged when the engine runs. When the switch is in the second position, the second battery becomes the sensing battery and the first battery is charged from the VSR. Having a fully charged battery always in reserve provides a significant safety advantage.
