Coleman CPX-6 compatible Battery Pack The CPX 13000mAh
thingiverse
This is my attempt to make a "custom" CPX-6 Battery pack for Coleman CPX-6 compatible devices. I was disappointed in the life I get from the CPX-6 Battery, about 5 hours at full strength with diminishing light output. So I set out to design a compatible case for a set of 9 old ex-Laptop battery pack Li-ion cells. Combined with a Li-ion charging module, and a separate USB module ( with discharge safety ) I get ~35 hours of constant light levels. It's held together by m3 bolts and brass inserts. A bit of filament and a spring makes the clips work. ( drop of glue in the rail keeps them there. ) I hope some one else has some use for this design, I uploaded the Fusion 360 File for easy modifications.
