Power from the alternator and from the solar system – the Pro Batt BBWS combines both in one device. The waterproof battery-to-battery charger from Sterling Power efficiently charges your service battery via the vehicle or boat alternator, automatically using the stronger source. This ensures your onboard battery always remains fully charged, even on long journeys or crossings.

Tip: Before first use, set the battery type correctly on the device – especially with lithium batteries, this is crucial for a safe and optimal charging curve.
