This box will fit 2 x 20700's and an NLPWM board. It will accomodate 30mm tanks and RDA's. It has 4mm thick walls.
It is a tight fit i suggest soldering your Vin and GND wire on the inside of the board oposite side away from the batteries. I surface soldered both large guage wires to leave more space.
