I was very skeptical of this dual battery charge controller since it was so cheap. I have an rv and a cargo trailer each with their own solar and batteries but i wanted to be able to send any unused power from my trailer over to my rv. I was able to make it happen using this controller. After the trailer battery is charged (usually by 9am), it sends any extra unused solar input over to the second battery in my rv.

Using this 2 charge 2 batteries in my toy hauler. It keeps the batteries charged via my 100 watt solar panel. Easy to hook up and program the settings.

Works like a charm! Have it charging the starting battery and electric trolling motor battery in my boat. Once one or the other battery is topped off, it automatically sends the *extra* current to the remaining battery. Couldn’t be happier. Great product.

Simple to wire and install and gives good indication of battery status

The unit allows a higher voltage battery to charge a lower voltage battery. Charge flow is not one-way. When they open the FETs, charge is allowed to go wherever it wants. This is not good if you have two different chemistries that need to be charged at two different rates.

I store my boat where there is no ready access to electricity to use the onboard charger. So, I use this controller with a 100-watt solar panel to keep my two marine batteries fully charged. The controller has worked flawlessly since installing it in 2017.

Works great when it can tell your battery is there. FYI, if your battery drops below a certain voltage it won’t charge it anymore. For example if you forget your inverter on. Don’t ask me why.
