Smart battery disconnect switch, 12V 24V manual remote isolator with digital display for cars, SUVs, minivans, electric vehicles

Features: 1. Complete protection for your vehicle's electrical system: Compatible with 12V (9-16.5V) and 24V (19-31.5V) DC systems, it offers three main protections: undervoltage, overvoltage, and overcurrent. It automatically disconnects in case of undervoltage of 11.8V ± 0.25V and overvoltage of 15.5V ± 0.25V for 12V systems, with corresponding thresholds of 23.6V ± 0.5V and 31.5V ± 0.5V for 24V systems. After an overcurrent trip, it allows for intelligent and delayed reconnection. A red indicator light instantly warns you of reverse polarity, essentially preventing battery drain, overcharging, and circuit damage. 2. Low power consumption, high-performance design, stable under heavy loads: With a static power consumption as low as 50 µA and zero standby power consumption, it effectively extends battery life when the vehicle is stationary. Capable of handling load currents up to 240 A, it easily manages high-current scenarios such as engine starts and the simultaneous operation of multiple electrical devices. Automatic protection activates when the current exceeds 240 A ± 10% for 12 V systems or 120 A ± 10% for 24 V systems, disconnecting for 10 seconds followed by a 120-second intelligent reconnection attempt, balancing safety and convenience. Designed for harsh environments: Rated IP65 for water and dust protection, it is resistant to rain, snow, muddy roads, and other challenging conditions. Operating temperature range of -29°C to +71°C (-20°F to +160°F), ensuring stable performance in extreme heat or cold conditions. A specially designed anti-malfunction mechanism prevents accidental power-off during engine start and refueling, providing a reliable and continuous power supply for long-distance driving, outdoor work, and similar scenarios. 4. Wide compatibility: This battery disconnect switch is suitable for vehicles with an engine displacement ≤ 4.0 L, including sedans, SUVs, off-road vehicles, minivans, pickup trucks, and new energy vehicles. 5. Dual remote and manual control: supports remote control (with priority) and manual button operation, with automatic identification for 12V/24V systems. Remote pairing is done in three simple steps: press and hold the pairing button to enter learning mode, then press the ON/OFF buttons to fire three flashes each for successful pairing. Stores up to 20 pairing codes, and a single remote can control up to 10 controllers simultaneously, providing flexibility for multi-user access or multi-vehicle management.
