Run your fridge and lights off a second battery while helping protect your cranking battery from going flat. This voltage-sensitive relay (VSR) links the batteries while you're driving and separates them when you stop.

• Automatic and manual modes
• Dual voltmeter display shows main and auxiliary battery voltage
• 15-second switching delay to stop chattering
• Sealed housing resists water, dust and vibration
• Suits lead-acid batteries

Fitting advice from Bryan: I'm trained in auto electrical. Use correctly rated cable and fuses, and if you're not confident with 12V wiring, have it fitted by an auto electrician. Got a question about your setup? Get in touch and I'll help you out.
