About Smart Lithium Drive

What electrical motors may I use with Smart Lithium Drive?

With our range of batteries, we do cover most of the needs for different electrical motors. Including electric motors for marine propulsion. If you don’t know what that means please, read this article. In order to have a suitable battery, please match Voltage and max motor size.

I have a 36V trolling motor.

Then you will need to have 3 individual, 12V batteries in series. You will also need a charger with 3 ports (or three chargers).

If you connect to the three batteries in the Multi Connect App remember to configure it to show the batteries in series (parallel is the default in the app).

What charging equipment do I need?

Please use any standard charger suitable for your voltage range either 12V, 24V. The bigger custom-sized batteries for yachts may also use standard chargers. But since the voltage is set by the customer it needs the charger to specify accordingly.

What lithium battery should I choose for my domestic power needs?

SMART LITHIUM Plug & Play is the best and most convenient solution for domestic power on a yacht or motorhome. You will find more info about the Plug & Play range here.
