Another point I mentioned already but feel need to put emphasis on now: If we here collectively develop a new battery solution the result will very likely remain an open source DIY kit for tinkeres and people interested in building their own experimental battery assemblies. Due to the regulations and certificates requires for bringing new battery products to the market we will most likely not be able to afford making it a real retail product..
