One would assume the cell is a standard Chinese brand cell and a part from the fear of getting fake cells, we would have to assume the it is the "western world" that is obsessed with brands and for obvious and understandable reasons. The brand offers some sense of comfort that you pay for quality, you get quality, however that said there would be a million Chinese folk out there who swear by a brand name we've never heard of and because a million plus people are using these batteries every day and trusting the quality, this Chinese brand could be equal or comparable to our known brands if not even made in the same factory or at the very least the factory next door.
Like you rightly say for the prices these batteries are nearly half the price of those with LG cells in them and if they only last 250 cycles thinking about it that's a good amount of charges, at 1 full charge per week, or about 50 charges per year, that's a five year life span if used in a sensible fashion and that goes without saying really.
Please keep me updated if poss - problems or impressions, good or bad - I am seriously thinking that a 48V battery with branded cells and high AH is going to cost too much and I might not even get the case I desire so I have put generic brand battery on the table thanks to you good sir!

I had hoped someone on here who had upgraded to a 52v might have one
