This is the same host jayrob is using in his kit. I did all of the machining myself, but I probably shouldn't have. It would have looked much better if jayrob would have done it.
Quite honestly, that little battery won't put out 800mA's... (Guessing)
Or if it did, it would not be good for it. And it would drain in like 10 or 15 minutes...
Here's what 275mA's/78mW's of 445 looks like: (my recommended max current for this build using a 445)
