The VEVOR split charge relay kit is a 12V, 140A relay with a 6-meter battery cable, sold as a complete install kit with screws and cable ties. It charges a second battery from the vehicle's alternator once the main battery is up, so a fridge or lights can run off an auxiliary battery without draining the starter. The 3-wire battery-only hookup means no alternator or ignition tap, which is simpler than relay kits that need a sense wire to the alternator. It is a basic voltage-sensing relay rather than a DC-DC charger, so it suits older vehicles and simple camper, ATV and truck setups; owners of smart-charging or variable-voltage alternators usually do better with a DC-DC unit.

Buyers of this class of split charge relay kit generally find it works for simple second-battery setups and is easy to wire, while criticising thin terminals and the lack of smart-alternator support.
This is a 12V split charge relay kit that charges a second battery from the main one. It connects with three wires at the battery and uses the vehicle's existing wiring. No alternator or ignition connection is needed.
The relay has an IP65 rating, which protects it from dust and rain. It has a silicone-sealed inner layer that resists vibration, and the shell is impact-resistant nylon plastic. The 6-meter battery cable has a flame-retardant pure copper core.
The kit includes the parts for a complete installation, such as screws and cable ties. It can be installed in ATVs, UTVs, trucks, motor homes and camping setups.
