Nice


curious about what brand you using for your Lithium Battery? I'm searching some to be able to travel w my 62hp Palette :)

Using this battery I found on amazon, again it is allowable for airline travel as it is 66W (needs to be under 100W). I have traveled by air with it and security did not give it a second look, although they thought my field microphone I was carrying was some sort of taser because of how the Zoom mics look :).
The battery lasts in my little 48hp for at least 5 hours and probably more as I have not done a real test of how long I can go before it dies or start seeing weirdness in the modules.

Great combo here, Portable to be used anywhere and a lot of variety for such limited HP.

Case is 48hp 4ms pod

FYI: One more observation about the battery, The only module issues I have ever seen with this setup is with a squid salmple I used to own. The squid turned on and seemed normal but would not take triggers for whatever reason.
