Protect your vehicle battery, avoid unexpected no-starts, and control power remotely with a rugged battery isolator switch designed for 12V and 24V vehicle systems. Key benefits Prevents deep discharge and ensures reliable starts: automatically disconnects when battery voltage falls below 11.8 V (12V systems) or 23.8 V (24V systems) after a 120-second delay to preserve charge and extend battery life. Wide compatibility: ultra-wide voltage regulation covers 6–30 VDC, so the same unit works with standard 12V and 24V vehicle series. Remote convenience and security: operate the isolator from outside the vehicle using the included remote; no need to access the battery directly. Low power draw and stable operation: extremely low standby current (700 µA) and 433.92 MHz frequency with self-locking mode for reliable signal and minimal battery impact. Clear status feedback: an indicator light shows ON/OFF state at a glance. Features and specifications Voltage range: 6–30 VDC — supports 12V and 24V vehicle systems. Automatic low-voltage protection: cuts power after 120 seconds when voltage drops below 11.8 V (12V) or 23.8 V (24V). Remote control frequency: 433.92 MHz with self-locking mode for consistent signal and simple operation. Standby current: 700 µA — minimal drain when the switch is idle. Operating temperature: -20 °C to +100 °C — suitable for typical automotive environments. Visual indicator: LED shows switch status (illuminates ON, off when OFF). How it solves common problems Eliminates dead batteries from long parking or forgotten lights by automatically disconnecting before deep discharge occurs. Lets you isolate the battery quickly without tools or battery removal—convenient for seasonal vehicle storage, maintenance, or theft-deterrence. Minimizes parasitic drain with ultra-low standby current, preserving battery life even when installed long-term. Typical applications Private cars: prevent battery drain during long trips or extended parking and start reliably in cold weather. Trucks and commercial vehicles: protect expensive batteries and avoid downtime caused by no-starts in fleet use. Motorhomes and RVs: isolate leisure batteries during storage or transit to avoid losses from onboard electronics and lights. Operation notes The unit is compatible with both 12V and 24V vehicle electrical systems within the listed voltage range. When the battery voltage drops to the cut-off threshold, the switch waits 120 seconds before disconnecting to avoid false triggers from momentary voltage dips. Use the remote to turn the isolator ON/OFF; the LED provides immediate visual confirmation of the current state. This battery isolator switch gives clear, measurable protection for a wide range of vehicles while minimizing its own energy footprint.
