LG M52VT sampes arrived today, so first results will be available this weekend I hope. Other cells are still on the way and as I will be on a business trip next week, the next results will be on June 3rd at best.

Added table results of LG M52VT in the second post and cycle life test was started. The sample I have tested is a disappointment. Unfortunately, the measured nominal energy 17.84 Wh does not reach the declared minimum of 18.34 Wh. And therefore does not bring any improvement over the M50LT.
The M52VT samples arrived in visually perfect condition, without any signs of use. But it is strange that they arrived with an OCV of 4.00V which is far from the factory declared shipping value 30 % SoC.
Let's see if Nkon will ever stock them again, then I would retest this model again.

Sounds like they were tested by someone, maybe at Nkon or maybe by their supplier.

Oh boy, 4V = I want a partial refund.
Shipping at 4V is likely not legal as well.

For clarification, I got the M52VT samples from a supplier BELIFINE (unknown to me) from alibaba. I will ask the supplier what he thinks about that.

There’s the remote possibility that they were a return (from a previous customer) too.
