Could you add for comparison the best in class non-tabless cells for suitable loads (up to 25A) ?

Absolutely. I am working as we speak on Molicel cells. I will keep adding daily new cells to the database. If you have any specific cell you want to request i can add it to the list and put them as priority.

Molicel p30b would be my reference point for 18650s. thank you
Is the next one on the line.
The 65P handles 30A better than the 60P that can't even handle 30A at 100% DOD without overtemp ? It thought it would be the opposite
That is correct. The 65P leaved the 60P in the dust. It has even a lower IR. Significant lower.
Do you think the 60P compares to the RH60 ? Btw, have you tested the RH60 already ? I thought the RH60 would be the new budget 6Ah 50S killer at an affordable price. The 65P is still very expensive (however, it seems like it's the perfect cell ever produced yet so worth it)

Basically, most modern all-tab cells designs tend to be very consistent and because of better thermal performance and internal consistency, balancing performance should be better as well.
Up to 40A test uploaded. I am still testing 45A, 50A, 60a and 100A.

60P is definitelly more powerful than RH60, it is close to RS60.

However, if I had to choose between thr Linkdata 60P and the RH60, I'd pick the RH60.
For longevity or something else?

Longevity, ease of procurement, extreme consistency, etc.

Example: when selecting 21700, 30ACC, all visible models, Voltage over time graph, then this gives a crowded graph with intersecting lines. Identifying the various colors<=>models becomes difficult.I need opinion and suggestions.

Suggestion: in the moving overlay, sort the entries from top to bottom according to voltages for that particular timestamp

an older visual representation is still available here (but molicel p28b was last entry added?). Still useful though.

I see that batemo got their stinky mittens on a murata VX-30 18650. Very curious to see what our review fellas here think of that one.

Will you be testing GreatPower’s or Amprius’s 60Q recently?Up to 40A test uploaded. I am still testing 45A, 50A, 60a and 100A.

@ZEUS-FL and and myself are now waiting for the samples to be delivered. The Amprius 60Q should arrive first, because availability of the GreatPower 60Q is a bit of a problem right now. Anyway we should have the results by the end of the month. At the same time, I'm also waiting for Tenpower 60XG samples.
Hi guys! Finishing the design of a racing motorbike pack -> 28S16P.
Peak discharge 600A -> 37,5A per cell
Constant current 300A -> 18,75A per cell
Minimun usable 7 kWh and 21700 format. Important aspects-> Looking for low voltage sag on peak discharges and low overall mass. Secondary is temperature raise.
Thinking about Linkdata 50T, Amprius 60Q, BAK 50D2, Tenpower 50XG...
If you could choose one, what will you choose? Do you think it will be better cells than this in 1-2 months? I need to make an order in 1 month or so... I know it depends on pack and current discharge rates but what cell gives you more confidence at a first sight?

Very recent information. The latest version of the Tenpower 60XG is excellent in terms of discharge characteristics, but unfortunately it suffers from very poor cycle life; based on my actual running test, it appears to last a maximum of 200–300 cycles, regardless of the discharge C-rate. It should be noted that this information is presented in the current datasheet. I'll have the first results for the Amprius 60Q in this discipline within 14 days.

Cycle life on 60xg was tested on latest version with production data starts like "zg313" ? Because l heard its mass production or on previously with "za"
