Does this look like a reliable 48v 20 ah battery ? It says they use LG cells in a lot of places and has good reviews. Their website seems brutally honest straight up calling its other cells "chinese cells" so I hope they are honest with these cells. Would love any opinions. https://www.amazon.com/gp/product/B099N6ZVZL/ref=ox_sc_act_title_3?smid=A323YRGVBR4QGU&psc=1If you don't wanna look at it, it's Unit Power Pack branded battery with apparently LG 4800 cells.
