JumperT16 FlyMore Pack

thingiverse

This battery lid locks in just like a standard Jumper lid but can fit four Lion cells in a 2S2P configuration, effectively doubling your mah capacity. You'll also be able to run another two cells in the stock location without the cell holder and four cells in this pack, tripling your capacity. But there's more - you can also use two cells in the stock location and a 3S1P configuration in this pack with just your crossfire. To do this, you'll need to provide a switch for the crossfire or add a relay circuit with the trip signal coming from the stock power pin when the external module is active. The pictures below show the version without refined edges. I recommend making a JXT Balance to xt30 pigtail so it's easier to remove the pack from the remote. ***********************************************UPDATE********************************************* I've created another version named "T16_JUMPER_HUMP_PACK_FINISHED_PACK.stl" that doesn't have the contoured cell position holder on the bottom. This is specifically for finished 4-cell 18650 packs with heatshrink over all the cells. The file "jumperpackfinalV2.stl" is better suited for naked 18650 cells without heatshrink. The lid is compatible with both available versions.
