Heart Horse 12V 140Amp Split Charge Relay Dual Battery Isolator LED Display

Works perfect.

Super easy to install, watched a couple of YouTube videos and done it myself with in the hour.

Great kit and super easy to install. Charges both batteries up brilliantly. Good price and quality. Happy with purchase and definitely recommend.

Works a treat quick insbtall no problems

Ray fit, great product . Love the voltage display and so do customers.

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.

Works great keeping battery charged!

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.

Fungerar som beskrivs. Saknar dock utgång för extern indikation av status.

Exactly what i ordered very happy with it. and it arrived earlier than I expected it.

Funziona veramente bene, non ha nulla a che invidiare ai relè di ricarica più blasonati che si trovano in commercio. Ne ho già presi diversi e mai avuto problemi. Interessante il display che indica la tensione di lavoro. Ovviamente si spegne dopo alcuni secondi e per visualizzare bisogna schiacciare il bottone. Il led di funzionamento invece lavora in automatico come sale la tensione.

***** UPDATE ******* Works as described. Nice to have digital display to confirm voltages. So far so good. Been installed a few months. ***UPDATE*** Installed last August 2025 and it’s end of March 2026 and it has failed! Comes with a 180 day warranty!!! About 200 days has passed since installed and it’s dead! I definitely would NOT recommend this product any longer as it has a very short life span and petty warranty. Keep on scrolling for a better brand or warranty at least….

je l ai installé et tout fonctionne bien pour le moment , on verra pas la suite
