Quick Summary
This is a 12V split charge relay kit rated at 140A and fitted with an LED screen display. It is set up to charge two batteries and includes wording about battery isolation, waterproofing and shockproof protection.
The relay is described as connecting the auxiliary battery once the main battery reaches 13.3 V, then disconnecting the main battery when voltage drops to 12.8 V. That makes the stated voltage thresholds an important check for buyers who need the exact switching behaviour.
Key Details

What to Compare Before Buying
- System voltage: This kit is for 12V systems, so check that your vehicle or setup matches.
- Rated current: The 140A rating should be compared with the demands of the batteries and connected equipment.
- Switching behaviour: The connect and disconnect voltages are part of how the relay operates, so confirm they suit your setup.
- Installation contents: The kit includes installation accessories, which matters if you want a more complete fitting pack.
- Display: The LED screen shows voltage, so check whether that is useful for your use case.
What Else You May Need
Any vehicle-specific installation requirements should be checked before fitting, especially if the wiring layout is being adapted to a particular battery setup. Follow the included instructions carefully and do not alter the wiring.
Common Buyer Questions
Does it charge two batteries?
Yes. It is described as allowing two batteries to charge at the same time once the relay connects them.
What does the LED display show?
It shows voltage.
What happens when the engine is turned off?
The relay is described as disconnecting the main battery when voltage drops to 12.8 V, helping isolate the main battery from discharge.
Before You Decide
Confirm that your setup is a 12V system and that the 140A rating and switching voltages match your needs. Check the included installation accessories and follow the wiring instructions without modification.
