Coupleur automatique de batteries doubles 140A 12V

korekt spannunh angezeigt

Auf dem Display wird die korrekte Spannung angezeigt. (Ich hatte ein anderes Gerät, bei dem die Anzeige nicht stimmte – gemessen mit einem Multimeter.)

Easy to install

Great kit with everything you need. Highly recommend for anyone who has a dual battery setup in their vehicle.

Garbage

You get what you pay for I suppose. Absolutel rubbish. Over heats, and cuts out! Even started smoking at one stage. Don’t waste your money 🤦‍♂️

Great Boat Accessory

This little thing works great! Used it on my boat to charge my trolling motor battery while my boat motor is running and with it in auto mode, it charges while the engines running and disconnects it after you shut it off and the voltage drops to around 12.6-12.5v. I do have to put it in manual mode when I plug in my multi-bank battery charger to keep it from turning itself on/off because of the voltage going up and doing the same as the alternator charging it, but that’s no problem because it only takes a 3-5 second button press. Works exactly as good as I’d hoped it would.

Nada más montarlo dejo de funcionar

Toimii caravaani käytössä hyvin

Suosittelut tälle,saa erotettua kaksi akkua helposti ja vapaa ajan akkukin latautuu ajaessa. Hyvä jos ei ole aurinkopaneleita katolla. Autossa tosin tarvii olla iso laturi kiinni moottorissa,mutta caravaani autoissa se puoli onkin kunnossa. SUOSITTELUT+++++

Very Satisfied

I'm glad I choose this relay. It really simplified my aux battery setup and works great. I even used it in reverse to jump start my van when I left the key on too long.

Funktioniert perfekr

Eingebaut im VW T5 um die Zweitbatterie zu laden. Macht genau was es soll. Das Relais schaltet bei laufendem Motor die Zweitbatterie in den Lademodus und wenn Motor aus ttennt es sie wieder. Bin begeistert.

Produsul este conform descrierii. Pretul e ok insa partea de logistica e cam greoaie. Urmarirea coletului este inexistenta

Heavy Duty Isolator 140a

Very happy with this high quality Isolator it has a low voltage cutoff so you will not over draw your primary battery, the other side connects to my second battery or my house batteries and automatically opens a flow of current to charge them while the car is running. It has a high voltage cutoff to protect the source or car battery and alternator from being damage and at the same time protecting the house battery from receiving too much current. This solved my problem of keeping my lead acid and Lithium charged. Best investment I made in a long time.

guter gerät immer!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

No Problems Yet! Was exactly as advertised.

Solved my issues. Installed 2 ahm batteries for air bag system. When compressors kick on the voltage doesn't even flicker. Batteries are always fully charged

Does what I needed it to

This was purchased to isolate an RV auxiliary battery used for starting the generator from the start battery bank for my engine. The original design had these two batteries banks connected together for charging purposes, but not isolated. Since the auxiliary battery was a smaller capacity battery it could drain the chassis battery during long storage periods leaving me with a dead chassis battery. Now with the battery isolator the two batteries are disconnected from one another unless the engine alternator, or other charging source, is supplying a charging voltage to the chassis battery. The battery isolator then applies the full charging voltage to the auxiliary battery, when needed, allowing it to recharge . Diode isolators have been used for this purpose and work ok, but they have a voltage drop across the diode which limits the charging that can occur. Diode isolators are solid state devices and can be susceptible to voltage spikes. This device is a much better solution. its rugged, delivers a full charging voltage to the load battery, and isolates the charging source battery when there is no charging voltage being applied. No dead battery after 6 months of winter storage.

extremely pleased

Love this product. It charges my Garmin Livescope battery as the boat motor is running, therefore allowing me to fish longer

Well worth the Money

Installed it 4 months ago as a bank up battery for my system and aux lights. Works as it should and works flawlessly.

Works well

Used it 2 add cranking power from multiple batteries. Works like a Charm!

alles super!
