For those wanting a more Stealthy and less Altoids look...  (I know right?.....Anyway here you go..)

All the same stuff, just in a shiny black box.  no external plugs, switches or lights showing. 
easy pop On/Off lid for access

the laptop antenna on top of the batteries. will not have the best performance especially when
compared to an external one.  


i think the the box was cheaper?, or it had free shipping when i picked them up?. 
anyway. they are super awesome.. as they perfectly fit 3x 18650's 
with just enough room for an ESP, or well an Altoids-point i guess.
