If you want to charge 12V batteries or a 12V powerpack, you may want this wiring kit which includes:
wire
terminal blocks
thermal fuses
mounting screws as shown in the video.
In order for you to use this wire kit, you will need to get a set of wire strippers and wire crimpers. Contact for availability.
Do-it-yourself Bike Generator Wiring Kit for Charge Controller
Suggested Tools & Accessories
Regular style fuse holder for cars
You can easily use a regular 20-amp fuse from AutoZone (or this one) or any other auto store, or you can use a thermal resettable fuse. The video instructions show a thermal fuse being used in Video #3. You can use either option. If you purchase the wiring kit you will receive the resettable fuse for your generator.
A thermal fuse gets hot when too much current flows through it and then opens up until you stop pedaling. This is called an overcurrent protection device. After 20 to 200 seconds, depending on how hot the ambient conditions are, the thermal fuse will cool down and the pedal power system will be ready to use again. This fuse should never trip, but if it does, it means there is something wrong with your wiring.
