For vehicles with two batteries, these devices electrically isolate the batteries to prevent the battery with the higher charge from draining into that with the lower charge. In addition, both batteries can be charged simultaneously from one source.
Electronic components are embedded to give excellent protection from adverse conditions, such as contamination and vibration
Integral heat sink provides efficient heat dissipation
More flexible than traditional battery isolators
Work with all types of alternators
Reduces the load on the charging system by not connecting the auxiliary battery until the primary battery is charged to 13.2V
LED status indicator
Optional start assist with addition of a momentary switch allows the auxiliary batter to assist the starting battery
