Quick technical Q&A

Is this compatible with Battery Tender quick-disconnect plugs?

Yes—this accessory is built around the common SAE-style quick disconnect used on many Battery Tender chargers and harnesses. Match plug color/type before ordering.

Do I need to add a fuse?

If the accessory includes an inline fuse, use it. If you’re wiring direct to a battery, always fuse close to the battery to protect the lead.

Any install tips?

Route away from heat and moving parts, secure the cable every few inches, and leave enough slack for suspension/steering movement on powersports.
