The cells are of excellent quality and have above rated capacity.These are by far the best batteries I have and I built them with Gobel Power Lf280K cells.I have batteries from other competitors that are not as good some I had to repair or modify to get them to work.If you start with quality cells your battery will perform better and last longer.The screen shows a battery charging for the first time,only EV grade cells do it that nicely.Thanks
