This is a sturdy voltage converter/regulator and it works well for what I was designing.I've ran a 10 amp water pump on it for a while and it stayed cool.The terminals are rugged enough, it looks fairly water tight and works fine for my custom design which is to supply a full 13V DC level to a 12V sump pump on a 100A-Hr battery back up where I need it to lift water 10 feet over a basement wall if needed on big thunderstorms and the power went out.A photo is attached of what the assembly looks like with the same brand of battery charger added.I use a control block (circuit) with a water pump float switch as an input to activate the pump.The switch I use has a timer + a long-throw float switch so it runs long enough to drain the sump and will alarm if there was an issue of not pumping.The control signal goes to an optional input switch on the converter which only needs a few mA to set the output ON-OFF. or just jumper that if you want it to remain on.This is more robust and adjustable than any battery backup system I could have bought and I've had several which all failed after a while.Using the DC Converter plus a regulated DC charge controller gives full, adjustable control of the charge rate, final voltage levels and maintains the battery with intelligent battery levels over time.Commercial sump pump battery backup systems tend to overcharge the battery eventually which wrecks the battery and runs too slow when pumping. This setup is superior when coupled with an intelligent charge controller and the DC converter.This design allows a 12V DC pump to run at FULL speed at 12.8 - 13.5V if I want and turn off quickly rather than pumping slooooowly at 12V or 12.4 and run the battery down because it takes too long.This method runs the DC pump at FULL speed and shuts off quickly which is less draw on the battery overall.I added DC breakers for protection of the battery, the pump and for the DC converter.This setup also works if you need backup batteries from a 12V vehicle battery 50-100 feet away and the voltage drops over the long distance and ends up too slow to run a pump.You can give the converter 10V or whatever and it will still output a full 12.8V or whatever you set it to.Of course, energy is still energy so if you feed 10V in and want 12.8V out then the input current will be higher accordingly.My only complaint is the DC adjustment screw is TINY, recessed, hard to see and made of plastic which is hard to adjust.That is the weakest part so get a small screwdriver that fits well so it doesn't strip out the plastic screw. The rest is well made.

I use this product to charge a 12v accessory battery in my work van without draining my starter battery. I have it wired to a simple 12v switch which I turn on when I need to charge my battery.It works perfectly. Installation was simple. The manufacture helpfully included terminals to connect a switch, requiring very little current so a cheap switch (vs a battery disconnect switch) will suffice.

When you want a reliable solar controller that will last and won’t have issues - get anything Victron. All their equipment is top notch and I paid the price with cheaply made bargain brands. They have excellent support and warranty all their products way longer than most. You won’t be disappointed. I am a boondocker and installed all my own equipment to camp off grid with a 400 AH lithium to 600 watts of solar with 3000 watt inverter. Victron has never failed me. Any negative reviews are inexperienced setups that should hire a professional.

Really like how easy the Bluetooth setup and automatic firmware update was. Works flawlessly.Wish the terminal screws were also square drive or phillips for better control.6 ga wire is a tight fit but works.

Works as expected, but runs very hot

I like Victron and all I needed was a simple 18 amp DC-DC charger and did not see the need for the significantly more expensive "Smart" version. The first time I used it, it would only charge at 12.3 volts. The starter battery is 14.4 volts so this charger was unable to charge it beyond 12.3 volts - not enough to start the vehicle. Since there was absolutely no directions on how to change the setting, I even went on the Victron Energy website but found no useable information. I removed the charger from it's mounting to find a small unlabeled hole to the right of where the wires connect. Using a flashlight I saw a small potentiometer inside. When I turned it to the right the voltage increased and I was able to set it to 14.4 volts. I wish they would have included this information with the unit. It would have saved a lot of frustration! Or at least have the hole labeled. I came very close to returning this unit but now with the voltage set correctly it should be fine for my intended use.

I noticed some people complaining that they are only getting 12.3 volts out of this, but this is not a DC-to-DC charger, it is a converter. You use this to convert a source power supply to a regulated 12 volts. It will up-convert a power source that is below 12v into a consistent, constant 12 volts by using a capacitor inside the unit.

Många parametrar som går att ställa in. Laddar i mitt fall lifepo4 batteri. Supernöjd.

Verwende es als Booster für die Bugbatterie im Segelboot. Bedingt durch die Leitungsverluste kommen von 14,8V Ladespannung vorne nur 13,9V-14,2V an, was für eine erfolgreiche Bulkladung viel zu wenig ist. Mit diesem Booster liegt jetzt immer die benötigte Spannung an, und die Elektronik erkennt ob LiMa oder Ladegerät läuft und schaltet überhaupt nur dann ein. Ein Laden auf Kosten der Startbatterie ist dadurch verhindert.

Si le chargeur n est pas Bluetooth est ce qu' il va charger une batterie au lithium
