The Sterling Power BB1230 is a Pro Batt Ultra battery-to-battery charger that takes 12V from your vehicle or engine battery and charges a 12V house battery with a proper multi-stage profile. It is built for RVs, camper vans, trucks and boats where the alternator alone never quite fills the house bank.
Wire it between the starter battery and the house battery; there is no alternator modification, no ECU tampering and no warranty issue. It switches on at 13.3V and off at 13.0V (double for 24V input), so it uses surplus alternator power rather than draining the starter battery, and Sterling says it charges 5 to 20 times faster than an alternator on its own. It is designed for smart alternators and regenerative braking on modern engines.
Features
- Activation modes: automatic, manual (for remote switching), and regenerative-braking modes with or without an ignition feed
- In regenerative-braking mode the input may drop to 12.2V (double for 24V) before it switches off
- Boosts or reduces voltage so the house battery gets the right profile whatever the alternator does
- 4-stage charging with 9 preset battery types including AGM, LiFePO4, gel, flooded and sealed lead acid
- Custom charge profile set from the front panel
- Night setting runs at half power to keep fan noise down
- Fireproof plastic case with no screws to corrode, thermal power reduction and multi-stage fan cooling
- Optional BBURC remote with 10 m cable (sold separately)
