A SBI is the ultra-simple and most technologically advanced method of automatic battery isolation system. These units can be installed between batteries with a common ground to automatically control the charging process to the batteries but continue to provide isolation of them when a charging source is unavailable. The small size and rugged construction of these units allow for quick simple installation for even the most novice Driver. To make things even better this unit is “Dual Sensing” which senses the charge of both batteries. If either battery is receiving a charge, e.g. a battery charger is connected to the auxiliary battery; the SBI dual battery system will engage and charge both batteries.
The advanced technology always insures that the first battery is fully charged (13.3v) before connection is made to the second battery. This prevents problems that may result from your charging source being too low in amps to charge all batteries as once. If placed in linear sequence between each battery the SBI 12v dual battery setup can provide proper charging for several batteries in a multiple battery setupsuch as in larger boats that may have 2 or more house batteries.
You can easily see by the picture of 12v smart battery isolator setup below the unit is designed to withstand moisture with the silicone covered circuit board. Although I would not plan on mounting in a position where it would be submerged it is certainly designed to take all the splashing, dripping, spilling, and other various wet conditions that would come along.
Notice also the clearly labeled connection posts and the black common ground lead. To be even more convenient all four sides is designed with “knockouts” so that you can easily route your connecting wires in any direction.
