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.
True dual battery kit sensing features
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 True Am battery isolator system will engage and charge both batteries.
The advanced technology always ensures that the first battery is fully charged (13.3v) before the 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 at once. If placed in linear sequence between each battery the 12v True Am dual battery kit can provide proper charging for several batteries in multiple battery setups such as in larger boats that may have 2 or more house batteries.
You can easily see by the picture of 12v True 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 are designed with “knockouts” so that you can easily route your connecting wires in any direction.
