Complete set with installation accessories. Never drain the starter battery.
Safety is paramount on the water. It is important to have power to start the engine on your boat, especially when you are in a natural harbor where assistance is limited. A traditional starter battery is also not designed to be drained, as this can damage the battery. Instead, use other batteries for this purpose and separate them into two battery banks with this complete kit.
This kit is for one starter battery and one service battery. In addition to this kit, you will need cables of the correct length and size, if they are not already on the boat.
