- Lithium, AGM or flooded profile set separately on each bank, so a LiFePO4 trolling bank and a lead acid starting battery can share it
- Wakes a lithium battery whose BMS has shut it off, instead of reporting a dead battery
- Per bank charge level lights for lead acid batteries
- 6 A per bank is slow for a large, deeply drained deep cycle battery

- Runs on 120 V AC only
