Customer Reviews for VEVOR Dual Battery Isolator Kit, 12V 140Amp, Manual and Auto Modes VSR Voltage Sensitive Relay with LCD Screen, Smart Battery Isolator for ATV UTV RV Camper Off-Road Vehicle Caravan Truck Boat Yacht

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+++++

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.

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

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.

amazing fast delivery.nice simple device, all installedand working. waiting to go on a trip.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

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

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.

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

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

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