Superb, EEL's design comes closer to perfection with each iteration. Many thanks to Eric John @ EEL Battery Shenzhen support for his resourceful, proactive and most friendly support. @ EEL managers, if you're reading this - this man deserves a commendation or bonus; he has been cooperating with us in our ongoing project to build something a little 'special' - a proof of concept/demonstration for a 'perfect battery', with lowest possible internal resistance. Once tested, approved, and operational, we wish to make a promotional video to amplify EEL's services on social media worldwide, and show the European market what quality Chinese crafsmanship can allow one to create.

This was my second buy , first one was smooth everything great cells well balanced with certificates from EVE, this second buy cells weren’t well balanced the certificate didn’t come with them, that’s why I give a 3 star as product is not as good as my first order and the cells do not work as good as the first ones.
