Dual Battery Isolator Kit can be widely used in a variety of 12-volt power system vehicles, such as motorhomes, crossovers, trucks, SUVs, etc., to meet the needs of different vehicles to add a secondary battery to provide more power support for the vehicle, and to facilitate the user to use a variety of high-power electrical equipment in the vehicle.
Function: When the generator works after the vehicle is started, it gives priority to charging the main battery, and then automatically charges the secondary battery when the main battery is full, ensuring that the main battery is always in a fully charged or highly charged state, providing a reliable guarantee for the vehicle startup and power supply of important electrical equipment, for example, even if the secondary battery has a lower level of power during driving, it will not affect the charging progress of the main battery.
This package is including: 1* Voltage Sensitive Relay 1* 20 ft red battery cable 1* 2 ft black ground battery 1*negative brass marine type battery terminalcable 2* positive brass marine type battery terminals 6* cable ties 1* tinned copper lugs 1*heat shrink 1* instructions
Rugged and durable: 12 volt dual battery isolator kit is made of high quality materials and advanced technology, with good high temperature resistance, shock resistance and waterproof performance, which can adapt to all kinds of harsh vehicle working environments, such as high temperature in the engine compartment, rugged and bumpy road conditions and humid climate conditions can work stably.
Low Voltage Drop: High quality isolator kits work with low voltage drop, which can effectively reduce the loss of power in the transmission process, improve the charging efficiency and power utilization, and ensure that the battery can obtain sufficient charging current to complete the charging process quickly and effectively.
