Works really well whenever I have to tether my battery pack to my light that is helmet mounted.
I see several possible solutions for the OP. You can try just using zip ties around the battery pack and through an onpening of your basket. Another idea is to use a large hose clamp around the battery pack and through the basket opening. For someone to steal that means they will need a screw driver to loossen the hose clamp. Or you can use both hose clamp and zip ties.
Third idea is to find a U-bolt clamp that is square shape and clamp your pack down. This will requure someone with a wrench to loosen the nut.
Another thoughts is to find a project box from Radioshack that fits the battery. Drill 4 holes in the bottom of the box and bolt that through a opening of the basket. Place battery in box and screw the lid with the original screw or maybe even replace the original screw with some tamper resistant screw. You will need to drill a large size hole for your battery connector to exit the box.
All else fail is to find some plumbers strap and strap that around the battery pack and through the basket. You can then use a bolt and nut or even a mini padlock around any two holes on the strap, just be sure it is tight.
