you're quite welcome and good choice on power source (the 3400s). are the cells protected or bare?I clamped it together and drilled out both halves, then redrilled one half for a tight fit. I tapped one half. All screws are allen key cap screws.
Firelord and Tobrien, thank you. That is very kind. I think my build quality will go up greatly in the next few months
The batteries are inside, its 2*3400 mah panasonic cells.
Unfortetly I forgot it at home when I left for college so parents will have to send it down to me...
