Thiss seems all around a VERY nice box for quality and price. The built-in battery is my only concern... Now on smoks website it says 2 built in 18650s. I have noticed alot of screews to gain access to inside. One should be able to pop her open, maybe bust a few solder tacks. Throw some fresh 18650s re-solder and be on your way when the original battery life starts to fade over time. Just a thought. It's not rocket science.
Any Ideas?
