Vehicle battery protection designed to stop parasitic drain and preserve starting power. The IMAYCC Remote Battery Disconnect Switch combines manual and remote control for reassurance when vehicles sit unused. Is it the right safeguard for cars, boats and trailers that spend long periods parked?
⚡ At a Glance
- • Cut-off Behaviour: Automatic disconnect triggers after 120 seconds when voltage falls below 11.8V, with remote lockout above 13.5V to prevent accidental shutdown while charging.
- • Best for: Owners of cars, boats, RVs, trailers and ATVs who need to prevent flat batteries and parasitic drain during storage.
- • Not ideal for: Vehicles with small pile head terminals or those that require unusual terminal sizes outside 9-13 mm and 15-17 mm ranges.
Automatic low-voltage cut protects battery health and extends service life. Remote and manual control give flexible ways to isolate the battery.
Protects battery during long storage – thanks to automatic low-voltage cutoff
Voltage is monitored and when battery voltage drops below 11.8V the switch cuts power after a 120 second delay, preventing further discharge. Power restoration follows normal charging above the threshold, with a protective margin of ±0.2V.
Reduced chance of a flat battery after weeks of inactivity, so vehicles start reliably even after prolonged parking.
Safe to use while charging – with remote lockout above 13.5V
Remote control functionality is disabled when system voltage exceeds 13.5V to stop accidental shutdown during charging or running conditions. Manual switch remains available for deliberate isolation regardless of voltage.
Avoids accidental cut-outs when alternators or chargers are active while still allowing quick manual isolation when required.
Handles heavy currents – thanks to 240A rating and 500A instantaneous capacity
Rated continuous current is 240A with an instantaneous current tolerance up to 500A, and standby current draw is about 3mA. Operating temperature range spans -22°F to 194°F for broad environmental resilience.
Suitable for most 12V vehicle electrical systems under normal loads, providing robust switching for starters and accessories.
✨ The 4 Key Reasons for IMAYCC Remote Battery Disconnect Switch
- Automatic low-voltage cutoff - Prevents battery drain after 120 seconds when voltage drops below 11.8V
- Remote and manual control - Enables convenient on/off without risking accidental shut while charging
- 240A continuous rating - Supports typical starter currents with 500A surge capacity for brief loads
- Low standby draw - 3mA standby consumption minimises parasitic drain during long-term storage

❓ Frequently Asked Questions
Q: How does the automatic cutoff work?
A: The switch monitors battery voltage and, when it falls below 11.8V, cuts power after a 120 second delay to prevent deep discharge.
Q: Can the remote control be used while the engine or charger is running?
A: Remote control is disabled when system voltage exceeds 13.5V to avoid accidental shutdown during charging or while driving; manual switching still works.
Q: Will it fit my battery terminals?
A: Terminal compatibility is for negative pole sizes of 9-13 mm and 15-17 mm, and it is not suitable for small pile head terminals; measure before fitting.
🏆 Our Verdict
Recommended for vehicle owners who want a straightforward way to avoid flat batteries and reduce parasitic drain. Automatic low-voltage cutoff paired with remote lockout and a manual override makes the unit a practical safeguard for cars, boats and leisure vehicles. Though upfront outlay varies, the protection and low standby draw offer sensible long-term value by preserving battery life.
