- Simple to install - connect to starting battery, auxiliary battery and ground.
- Work with all types of alternators
- Smaller and lighter than traditional isolators
- There are no efficiency losses due to diodes
- Allows bidirectional 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 13.2 V
- LED status indicator
- Optional start assist with addition of a momentary switch allows the auxiliary batter to assist the starting batter
- Quiescent current 5mA typical, 8mA maximum
