Love these ideas! zip ties have patched me up to travel on multiple times.
I found a great rechargeable battery that has alligator clips for a jump of a dead motorcycle battery. it also has a pretty good LED light to light repairs at night.
Not exactly this one but looks like it. (mine is branded dbpower) :
(EDIT: I can't post links yet, just search dbpower motorcycle lipo jump battery)
Googling Cycle Gear, here's some info on an auxiliary battery they market (many other choices available):
Item #: 1000105
POD X1 Power Supply & Jump Box
The days of getting stranded with a dead battery are a thing of the past. Now you can easily transport back-up power anywhere you go and not worry about coming back to a dead vehicle battery. Just pull out your Power On Demand X1 and get going again and again.
The POD X1 is the world's smallest jump starter and weighs only 8 ounces. Not only will it jump start any car, truck, motorcycle, or motor sports vehicle, it also powers and charges all of your electronic devices, such as: iPods, iPads, tablets, cell phones, GPS units, PSPs, MP3 Players, Bluetooth devices, and more. So small it will fit in your pocket, charge it once and take it anywhere.
Size: 5.2 x 3 x 1 inch
Weight: 8 oz
Output: 5V 2A
Input: 12V 1A
Starting Current: 200A

Up to 20 jump starts in one charge

High power LED flashlight with 3 functions: flashlight, strobe, & Coast Guard approved 'S.O.S'

USB to 3-way Accessory Adapter (Apple 30 Pin, Micro USB, Mini USB)
One of these belongs in an EMERGENCY kit, IMHO.
