- LED voltage display shows battery voltage in real time, helping you monitor charge status at a glance. - Energy-saving theft protection: rated 240A at 12V with standby current of 3 mA. Automatically disconnects when voltage falls to 11.9V ±0.2V, reducing parasitic drain and protecting battery life. - Automatic shut-off for efficiency: if voltage drops below 11.9V, power is cut after a 180-second delay. When voltage rises above 13.2V, the remote control is disabled to prevent accidental shutdowns during operation. - Low power consumption, reliable performance: operates from 42°F to 194°F (5.5°C to 90°C). Standby 3 mA. 240A at 12V rating; supports up to 500A short-term; cutoff threshold 11.8V ±0.2. - Versatile compatibility: panel leakage indicator to monitor leakage current. Suitable for most cars, trucks, RVs, trailers, motorcycles, and other 12V vehicles under 4.0 L displacement. Negative terminal sizes compatible with 9-16 mm. - Common applications: - Parked vehicles or boats to prevent battery drain during storage. - Integration with aftermarket alarms, remote starts, or security systems. - RVs, campers, trailers, or tow setups needing reliable battery isolation on the go.
