Use our Power Adapter Kit when using the Power Pack Battery Box atop a kayak to reverse power through a Power Port to a Power Panel Switching System stowed away inside the hull. The positive terminal can be exposed when using this kit, so make sure to connect or cover the accessory side of this adapter first, before connecting to the battery. Disconnect the battery side first when disconnecting. Note: Make sure the plug-and-play connectors are completely pushed together when connecting the system together. Yak-Power uses our own custom tooled, high tolerance, very snug fitting connectors with larger gauge, real copper wire to ensure a quality, weatherproof and reliable connection. All our plug-and-play accessories are specifically designed to work together while maintaining the correct battery polarity throughout the entire Yak-Power system. Using other aftermarket connectors or splicing other connectors into the YP system may cause damage to the system or the accessories connected to the system and may void your warranty. Caution: Make sure to pay attention to the actual wire colors of all our accessory cables to ensure that the red (+) wire is always connecting to the red (+) wire on the connector into which it is being plugged.
