Hello Chris (@VeConcepts),
I noticed in the other thread, that you’ll eventually convert from a surfer to a paramotor pilot 
what’s your commercial battery going to be? Lithium Ion? Lithium Polymer Pouch Cells?
Most, if not all Pilots who have received their batch 1 and 2 OpenPPG kits have gone the Lithium Polymer Pouch Cells route, I am one of the few who decided to go the 18650 Li-Ion route.
Have you noticed my build thread?
I am close to completion: 13S15P Battery Pack Build - #96 by etienne
Just curious!
