The newest 21700 cell on the market and the most high capacity cells so far in the new format. Surpassing Samsung 48G with 200mah and testing confirms they are a whopping about 5100-5300mah! The datasheet was finally release and the dicharge current is max 7A and recommended to be as low as 1A so its not for high amp usages and fast charging. How ever in 250W ebikes this might be a breakthrough!

The price per cell was 5,75€ with express shipping and not added tax which compared to Sanyo GA (4,36€ with same shipping) is really good. LG is 870 mAh per € compared to GA which is 802 mAh per € so the price already better then the leading 18650 cells. LG M1 is the first 21700 cells that offers more mAh per € then leading 18650 and might be the cells that starts the transistion to the new format.

However the cells i got was from a sampla batch so availability so far i very unsertain. Since the price and capacity is so good i believe many large companies will snatch upp most of the cells before the reach the consumer market. Since they are low amp the they will not be used in electric cars, mopeds or powertools but maby powerbanks, flashlight, some ebikes.


Images and testing will follow.
