Egis Mobile Electric 8710-1400 XD Flex 2 Single VSR Without Knob Tinned Wires

The Egis Mobile Electric XD Flex 2 Single VSR (Voltage Sensitive Relay) is a high-performance automatic battery combiner designed for marine, RV, and powersports applications. This version features tinned wire connections and is supplied without a manual override knob, ideal for installations where a clean, low-profile mounting is preferred or where the override function will not be needed.

The XD Flex 2 operates as a voltage sensing relay that automatically combines and isolates batteries based on detected charge voltage. When the primary battery reaches a set charge threshold, the VSR closes to allow charging current to flow to the secondary battery. Once the voltage drops below the threshold, the relay opens to protect the primary battery from discharge.

Key Features:

• 500 Amp continuous capability per relay for high-demand applications
• Extremely compact footprint — designed to fit in tight engine compartments and electrical panels
• Available with or without intuitive front-facing manual override knob (this listing is without knob)
• Tinned wire connections for superior corrosion resistance in marine and harsh-environment installations
• Automatic voltage sensing relay (VSR) operation — no manual intervention required under normal conditions
• Protects starting battery from being drained by auxiliary loads
• Suitable for 12V dual-battery systems

The Egis XD Flex 2 is engineered for reliability in demanding environments, making it an excellent choice for boats, motorhomes, off-road vehicles, and other dual-battery setups where dependable battery isolation and automatic charging management are essential.
