Feature 1This kit provides all the cables, accessories and VSR needed to install the secondary battery with the VSR. 2VSR can fully charge the battery at any time, avoiding the possibility of battery exhaustion and towing at sea. 3Automatically combine two batteries when charging, and isolate two batteries when not charging. 4No voltage drop compared to battery isolation diode (0.6V). 5Dimensions suitable for heavy-duty modular fuse box series (BF43x) and battery switches, in line with mainstream products on the market 6Rugged fiberglass reinforced nylon case. Built-in LED indicator (turn on when VSR starts). 7Remote LED port (not including LED) indicating VSR status 8If the VSR device is installed in a place where it is not easy to see, you can connect an external indicator light and install it in a place where the operator can easily see it, such as the instrument panel. The negative pole of the external light is connected to the black wire to be cut on the VSR device. 9Surface or panel mounting options provide flexibility during installation. 10Optional memory mode enables zero power consumption when the engine is turned off. 11When you do not need this device (VSR) function, you can cut the red wire to connect an ON-OFF switch to control the power on and off of this device. 12Usually used when the boat or yacht is not in use for a long time, turn off the VSR to achieve 0 power consumptionCondition: 100% Brand NewItem Type: Battery Isolator Color: Shown as PictureMaterial: CopperRated Voltage: DC12VCombined / Open Circuit Voltage: DC 13.3V / 12.8VContinuous Rated Current: 125AIntermittent Current Rating: 40APower Consumption: 10mA (standby) 330mA (pull-in) / 0mA (Storage Mode)Functional Example:After the engine stops, the House battery on the left is discharged to the load device on the upper left. When the battery voltage is lower than 12.8V, the VSR is turned off.The startup battery on the right does not discharge to the deviceWhen the left battery is not charged, the battery will run out.There is at least a small battery on the right side that allows you to start the engine .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x 6 Meters Red Cable Terminated At Both Ends1 x 600mm Black Earth Cable6 x Cable Tie1 x Sensitive Relay1 x Bottom Cover2 x Marine Battery Positive Terminal1 x Marine Battery Negative Terminal2 x Heat Shrinkable Tube1 x Copper Crimp Terminal (for Red Wire)2 x Copper Crimp Terminal (for Black Wire)4 x Mounting Screws1 x Manual
