Here's what you need something like this. Could probably make it out of parts for less though.
2-Piece Motorcycle Jumper Cables
A 2 piece jumper cable system where you leave one part constantly connected to your battery and only have to carry the "jumper" section. It's strong, light, easily stored and easy to use.
The "whip" that attaches to your battery is 18" long, so you can easily place the connector plug out of the way and out of sight until needed while the Jumper Cable section is 12' long so you have plenty of room to connect up to another vehicle.
Part of the benefit of these cables is, unlike other 2-piece jumper cables, it uses the same 2-pin connector that other accessories like Battery Tender chargers, heated clothing, and air compressors.
One thing to remember when using the jumper cables in conjunction with other accessories is that, to use our jumper cables, you MUST
replace the whip that came with your Battery Tender or heated clothing with the Jumper cable whip. The one that came with other accessories is a smaller gauge wire (usually 16-18awg wire) and will not carry the current to jump off a bike or atv. The EZ-Jump cables are a heavier 10AWG wire to allow for the larger draw from jump starting.
