At a glance

The listing describes automatic battery connection above 13.3V and disconnection when voltage falls to 12.8V, with a manual mode also described.
The LED display indicates voltage status. When two batteries are connected, the listing says it displays the higher-voltage battery.
The listing claims an IP68 waterproof rating. Treat this as a manufacturer claim, not an independently verified result.
The title identifies a 5M kit, while the accessory details list red power-cable sections of 4m, 0.5m, 0.25m and 0.25m.

Pros and cons

Pros

Automatic voltage-sensitive switching is paired with a manual mode, giving the installer a choice of operation.
A displayed voltage can help show the relay's status without relying solely on an unseen switching event.
The listed kit includes multiple cable, fuse and connection accessories, potentially reducing the need to source basic installation parts separately.

Cons

Installation depends on correctly tightened wiring connections, as the listing itself cautions.

Customer feedback reports positive impressions of quality and functionality, including suitability for campervan builds, and some buyers describe the kit as good value. The overall rating distribution is mostly five-star but includes a meaningful share of lower ratings, so experiences are not uniformly positive. These perceptions may help inform a campervan build decision, but do not verify the stated current rating, switching thresholds or installation contents.

Frequently asked questions

At what voltage does the relay switch?

The listing says it connects when input voltage exceeds 13.3V and disconnects when voltage drops to 12.8V. These are manufacturer-stated thresholds.

Does it have a manual mode?

The feature description and instructions describe manual and automatic modes, but the technical details list the operation mode as Automatic. Confirm the selected kit's controls if manual operation is essential.

What does the voltage display show with two batteries connected?

The listing says the display shows the higher-voltage battery when both batteries are connected.

What comes in the kit?

The contents description lists an isolator, earth cable, fuse holders, battery terminals, red power-cable sections, fuses, ring terminals, heat shrink, sticky pads, cable ties, screws and an instruction manual. The product-details box list only names the Split Charge Relay Kit, so check the selected listing's package contents.
