Smaller and lighter than traditional isolators. There are no efficiency losses due to diodes. Allows bi-directional charging from the alternator or from shore power. Reduces the load on the charging system by not connecting the auxiliary battery until the primary battery is charged to 13.2V which extends the life of charging components. LED status indicator. Optional start assist with addition of a momentary switch allows the auxiliary batter to assist the starting batter.
