✔️ IP65 waterproof rated with 5V20V readout and toggle switch

This heavy duty dual battery isolator kit runs two power sources off a single alternator without dragging down your starter bank. You mount it directly inside camper vans, flatbed trucks, RVs, boats, and off road rigs where reliable backup energy prevents stranded scenarios.

✅ 140 amp continuous load capacity for demanding 12V electrical systems
✅ Auto and manual switching modes plus customizable delay timer up to 60 seconds
✅ Adjust cut in and cut out thresholds between 11.0V and 14.0V for lead acid or lithium banks
✅ Sealed silicone gasket meets IP65 standards against dust moisture and engine vibration

💡 What stops starter battery drain when running high demand gear overnight?
A smart isolator module keeps your house bank topped off while leaving plenty of juice for morning ignition. This handy setup handles load spikes gracefully by locking contacts open below 12.7 volts to protect your primary source.

- Captures alternator current reliably once the reading climbs past 13.3 volts without stealing cranking amps
- Ignores temporary voltage dips thanks to a built in delay that prevents rapid contact chatter and heat buildup
