Heart Horse 3m Split Charge Relay Kit,12V 140Amp Smart Dual Battery Isolator Kit Manual/Auto Modes VSR-Voltage Sensitive Relay Kit with LED Screen, Voltage Display for Truck,SUV,RV,ATV,UTV,Boat

The kit arrived with all components as described. Relay, ready-finished cables cut to length, fuse holders & fuses, screws, cable ties, etc.Installation was easy, my only observation was the enclosed leaflet/instructions doesn’t show installation of fuses to each battery, so be sure to follow the wiring diagram shown on the web advert.All worked well first time.

Exactly as advertised. Highly recommended split charge relay…

Easy to install. All the parts you should need... but if your vehicle battery is in the engine bay (not in the cab/under a seat) you might need a bit more red cable. (I fitted to VW T5 and just had enough red cable.How I fitted to VW T5:Starting at the battery under the bonnet. I routed the red cable thru a rubber grommet under left (passenger) side of the windscreen scuttle panel. Then routed it under the carpet covering the wheel arch. Then under the plastic step and mounted the charger box to the plastic step in the passenger side door opening. Then located the leisure battery behind the passenger seat with cables from the charger box routed under the carpet... I hope this helps someone, otherwise I've just wasted 4 mins of my life.

Arrived super fast, and all seems like good quality unfortunately unable to install it as there are missing wire.UPDATE: Seller is very prompt in resolving the issue to ensure this doesn't happen to future orders. Thank you.

As described by the seller and quick delivery.

dont get 3m of cable and the cable is under sized and a risk at best

Easier to install as smarter than the old split charger relays as detects voltage from the battery itself, rather than from alternator trigger wire. Solid state means no electronics exposed to moisture/physical damage. Display handy to see what's going on. Recommended!

Great bit of kit, easy to install and fully documented in the instructions.My only concern being the pcb coating (like a rubber / gel) grinding away when the terminal was fitted with a wire / connection and the nut was tightened.

After installation, the wattage to my 2nd battery increased significantly (faster charge). Plus, a second auxiliary battery also charges efficiently at up to 128 watts. That has been a wonderful surprise. Starter battery seems unaffected (that is, charges normally). Very impressive current isolation.The package is admirably kitted with extra terminals, connectors, either isolating or through. If your additional battery is not sited within 10 feet (3M), you will need additional current gauge wire (1 wire - hot). I needed another 3M to get to the other side of my truck and back to the pickup bed. I used one of the connectors supplied in the kit between the supplied hot and my extension. Heavy duty terminals were supplied in the kit.Ensure that your aux battery to ground is good. My first attempt was faulty, causing an hour of continuity debugging to find the issue.All in all this product works well. So far (2 weeks service) I’m loving the faster charge rates to both aux batteries and no affect to my starter charge.

La verdad que muy bien, viene sellado con una capa tropicalizada y bien aislado funcionando muy bien.

Bij ene schema is de startbatterij boven.... bij ander schema is het beneden

Tutto come da descrizione!! Grazie!

Bonjour j'ai monté ce relais il y a environ 5 mois sur mon fourgon aménagé, il fonctionnait très bien et il est grillé depuis une semaine ! Ce produit n'est pas fiable...
