### Descrição do Produto
O Kit Isolador de Bateria Dupla de 250 Amp é a solução definitiva para quem busca eficiência e segurança no gerenciamento de energia em veículos. Este isolador inteligente de bateria garante que a bateria principal esteja sempre carregada e pronta para dar partida no veículo, funcionando como se houvesse duas fontes de energia separadas para cada bateria, mesmo com apenas um alternador. Com um design compacto e robusto, este kit é ideal para uma ampla gama de aplicações, incluindo caminhões, ATVs, UTVs, barcos, RVs e veículos off-road.
O Display de Voltagem integrado permite monitorar em tempo real a voltagem das baterias, com valores que variam de 13.5V a 16V para sistemas de 12V e de 27V a 32V para sistemas de 24V. O isolador desconecta automaticamente se a voltagem cair abaixo de 12.5V, garantindo a proteção das baterias. Além disso, há um atraso de 5 segundos ao conectar ou desconectar, evitando picos de corrente que podem danificar os componentes elétricos.
Este kit é compatível com Baterias de Lítio, pois inclui um cabo de conexão específico, permitindo que veículos equipados com baterias de lítio mantenham um desempenho estável. A instalação é facilitada por quatro furos de fixação, tornando o processo rápido e eficiente.
Com uma capacidade de corrente de 250 Amperes e voltagem universal de 12/24V, o isolador de bateria inteligente permite que você inicie o motor sem preocupações, mesmo que a bateria principal esteja descarregada. Basta pressionar o botão de emergência e ativar a bateria auxiliar para uma partida rápida e sem complicações.
### Instruções de Uso:
1. Instalação: Utilize os quatro furos de fixação para instalar o isolador em um local seguro e acessível. Conecte os cabos da bateria principal e da bateria auxiliar conforme as instruções do manual.
2. Conexão: Após a instalação, ligue o sistema e verifique o display de voltagem. Certifique-se de que a voltagem esteja dentro dos limites operacionais.
3. Monitoramento: Utilize o display LCD para monitorar a voltagem das baterias em tempo real. Se a voltagem cair abaixo de 12.5V, o isolador desconectará automaticamente.
4. Partida de Emergência: Em caso de bateria principal descarregada, pressione o botão de emergência para ativar a bateria auxiliar e dar partida no motor.

So far it works perfectly. Does what it’s supposed to. Would purchase again.

Once I found a spot to attach the device it was very easy to wire up. Attaching it the chassis was the hard part.
Apparently you do not need the red wire connected unless using a lithium battery.
The instructions say that the yellow and black wire go to a switch to manually connect the batteries. I found that the black wire is just ground so I only needed to run one wire to the switch with the other end locally grounded. I used the same ground to install an indicator from the blue wire. Now I can see that the batteries are connected with the indicator.
It seems that the solar charger for the house battery may also activate it as well so the chassis gets charged. I’ll update if I find that I’m mistaken on this.
I did find the instructions for the blink patterns to be not super helpful .

Installed it more than a month ago and it is still working fine.

I purchased this unit to install in my 2017 Thor Citation motor home. We purchased the RV used and I noticed that the house batteries would only charge up, on shore power. The engine alternator did not connect to the house batteries at all. I investigated whether or not they SHOULD be charging but only got mixed information from the RV forums. I decided that I would just bite the bullet and install one of these, no matter what.
As it turns out, the Thor Citation IS equipped with a solenoid that is supposed to connect the two battery systems together when the alternator is working. BUT my solenoid was bad.
I could have cheaped out and just bought a simple starter solenoid to replace the one that came with the coach, but that one failed; Probably due to arcing when the mechanical contacts made and broke each time the vehicle was started. So instead, I just removed the old solenoid and replaced it with this solid state unit. It was EASY. The job took just a few minutes to swap existing wiring. If the wonderful “German Engineering” hadn’t hidden all of this under the driver’s seat of the RV, I would have been done in 15 minutes instead of an hour.
We’ll see how long it lasts, but SO FAR SO GOOD.
I dinged the unit one star because, as others have already stated, the “emergency start button” is located on the same panel that the connections are on???? C’mon guys. The meter and buttons should NOT be on the same panel as the high current connectors! I could have installed the box next to the side panel of the seat and had easy access to the display and the button if they had only been on a side by themselves.

I have this installed in my vehicle containing the main lead acid starting battery and lithium iron phosphate battery for my solar installation. I have the solar controller connected directly to the lithium battery and during long idle time it eventually connects both batteries so both batteries always stay charged. Also, when vehicle engine is started the lithium battery is connected to the starting battery so both can charge but there is a slight delay so the secondary battery won’t get damaged during cranking the engine. This device works 100% as it should as long as it is correctly installed with one of the wires going to the ignition positive connection.

I most likely would have awarded this Dual Battery Isolator 5 stars if the instructions were not so confusing and contradicting! Before ordering, I watched the Charlie Chaplen style silent instruction vedeo several times, it never mentioned the need to purchase a 300 amp fuse (which delayed the completion of the install by 4 days) and the explaination of the addtional black wire contradicted the poorly written printed instructios!
Sure wish there was an American made alternative!

Seller unfamiliar with , or not knowledgeable on the product. The Isolator, is powered by the Car Battery: The Main battery. It draws power, and gets very hot when in use. After waking up, it remains “in use” with lights on and radiating body very hot for most of a day. That draws power from the Main Battery. This unit has killed a brand new AGM car battery. I would have expected this to draw power from the secondary battery. The whole idea of the unit is to ensure that the main battery is not drained. That is why it isolates the main battery from the load on the secondary battery. This unit is itself a load, and over a few weeks it kills the battery. Repeated draining, will mean needing to buy a new battery.
After reaching out to the seller, and repeatedly answering questions he asked, the seller just fades out.
He may have refunded my money originally. I don’t remember and the invoice is confusing. BUT that refund was due to the pain it was to figure out what their awful microscopic instruction card in the box, said. Many here complained about that. Eventually I figured it out, and installed it, only to find that it is killing the main battery!

Think of the yellow wire as a remote emergency start switch. If you bury the dual battery isolater somewhere where you can’t reach the emergency start switch the remote borrow wire (yellow) can be used as a remote emergency start switch on your vehicles dash. The yellow wire when connected to ground (switched on) causes the car battery to connect/borrow from the auxiliary battery to start the car. After car starts turn borrow switch off so batteries are isolated again. Blue wire powers a light to indicate your batteries are connected (in borrowed mode) light on. When in isolated mode light is off. Blue wire connects to one side of the light and the outside of light to black/ground wire. Red wire is for lithium battery auxiliary only. In lithium battery use connect the red wire to the ACC (accessory side of the ignition switch). When you insert the key into the ignition switch and turn it to the left you are turning on the ACC circuit. This connection helps maintain the stable performance of the car battery. It took a lot of reading/research to figure what they mean by borrow switch. Hope this helps.
