Protect your auxiliary battery bank from self-discharge with the Sterling Power BM12123 12V to 12V 3A smart battery maintainer. Replacing high-draw voltage sensitive relays, this advanced unit uses silent solid-state FET technology to draw less than 1mA of standby power, making it perfect for low-current solar or wind power installations. It automatically engages at 13.3V to route excess power, providing safe current-limited trickle charging for your boat, caravan, or motorhome.
| • SOLID STATE FET DESIGN: Utilizes advanced electronics to eliminate mechanical contact wear
• ULTRA LOW STANDBY DRAW: Consumes less than one milliamp to preserve solar current inputs • AUTOMATIC THRESHOLD ENGAGE: Activates the charging loop when main line reaches thirteen point three volts • INTELLIGENT CURRENT LIMIT: Protects internal circuits from high engine starter motor surges • SILENT NOISELESS OPERATION: Eliminates the constant clicking common with voltage sensitive relays | • TRICKLE CHARGING EFFICIENCY: Keeps auxiliary banks topped up against internal self discharge
• LIGHTWEIGHT COMPACT CASING: Weighs only two hundred fifty grams for easy mounting anywhere • STABILIZED POWER TRANSFER: Mirrors input voltages safely with minimal internal voltage drops • IDEAL SOLAR ASSISTANCE: Directs low generation power streams to secondary banks perfectly |
