This article will explain how to charge your batteries in the field, in case you are running low on batteries and your project is not yet complete.
You'll need a charger with a voltage between 11V and 18V direct current (DC).
The usual voltage provided from the vehicle is 12 V.
Where and how should I connect the cables?
First, connect your cables from your car battery to the Wingtra charger. Be careful to connect the positive and negative poles to the correct clamps: the red clamp connects to the positive (+) pole, and the black clamp connects to the negative (-) pole.
While charging, make sure that all of the other devices in the vehicle are turned off, i.e., radio, windshield wipers, etc.
Make sure that the cables are close enough to the Wingtra charger so that they cannot disconnect from the vehicle battery during the charging.
Connect the wires from your car battery to your Wingtra charger as shown in the pictures below.
Turn on your vehicle, and don’t turn it off until your batteries are fully charged.
Make sure that your charger and batteries are on a flat surface so that they don’t slip during the charging and cause accidental contact between wires that could cause a short circuit.
To avoid overheating of your vehicle and your Wingtra charger, please avoid direct sunlight and charge your batteries in the shade.
