That’s interesting. Curves similar to the LG MJ1, yet slightly better most of the times, slightly worse than the NCR18650GA, most likely a tradeoff for improved cycle life. If Vapcell hadn’t told us already that it is “Tesla Panasonic NCR18650BG rewrapped” I would be at loss.

Price is very cheaper than GA or 18650B
