The two threads you mention both relate to the Kick, but have different subjects. Please re-read the OP and feel free to contribute.
I'm right there with you, although I may move forward with modding with the Kick. It's a nice module. It really does kick! My only issue with it is that because it neccessitates using a smaller battery and draining the battery's amps for boosting, run times blow goat. The only happy, fidget-free solution I can come up with is to parallel some larger batts for all-day use with the Kick.Same here, oldblue. The drop-in module is nice for those who don't mod and for use with existing PVs without having to mod them, but the possibilities should really open up once the modder's board comes out and I can't wait to see the specs on it and what people do with it
My plan is to go with 4x18500 or possibly 4x18650.
That is incorrect. The kick can be used with mods with mechanical switches. Just not with vv mods that have their own system.
The Kick has a little grounding wire/spring that needs to get connected to the ground of the mod--usually by just fitting in the tube tight enough. That wire needs to touch the metal or be connected to the ground with appropriate wiring. Phidias (wood feeder) is now being sold wired for a Kick. Reo's have been modded quite easily with a little sanding and sometimes a couple other tricks. There may be other's making their mods "kick ready".
If it's a tube mod -- IMO it is easier if you can load the battery from the top and put the kick on top of it.
