I built a battery pack and adapter for my hopper and it works amazingly well.
I would like to hear any ideas on improvements (the box, the cord, the materials, anything) or any criticisms you may have of the design or any safety issues we can think of?
I am still trying to narrow the final design down in my head as this is the first and it is a bit rough looking. I used JB Weld to secure my negative contact in place and to glue in the cord in place on this one but on future designs, I plan to use pressed in contacts. The positive contact on mine was actually a part from another product that I adapted to get this working easily. Those that have already PM'ed me about this, I consider them to be on my short list in order, at the top.
I am assuming all hopper threads are equal, this may be a mistake on my part? So far, I have only seen 4 bodies and 2 back ends, but the threads were all the same.
Once I nail down the parts, I can work on figuring out the price! The wife just said "GO DO IT"...
My post in the Hopper thread has some more info.

- 119+ full power hits per charge compared to a new stock battery, which gave me 6 full power hits.
- It runs off (4) Sony 18650 batteries and requires no modification to the Grasshopper itself.
- The Aluminum piece also works as heat sink, that pulls excess heat from the hopper body and back end.
- No internal battery to get hot from use to add to the heat issue.
- No constantly swapping out dead batteries, cleaning threads, wearing out the contacts.
