Tabless design cylindrical cells tests

[Pajda]

Btw. I am not sure if BAK 65E and Molicel M65A are tabless?

May have jumped the gun on this one, edited the post. Good catch!

if only they were lol, but I bet they were aiming for a decent price

@Pajda Any plans for Tenpower 50SG?

 

[Pajda]

Actually, I did consider adding the Tenpower 50SG as a third contender alongside the Samsung 50S and the Lishen 50LE. I expect the 50SG to offer decent battery life, though not as good as the 50LE’s; on the other hand, it should be more widely available than the Lishen. ... But then the Reliance RH60 arrived.

 

[belllfador]

First impressions from two RH60: both cells are almost the same, at 3.6V ACIR is 6.5 mOhm, DCIR is 11.5mOhm, capacity 5870mAh @5A down to 2.5V @1A, 20.96Wh, 68.56g.

Have you tested Linkdata P60B? Looks not bad with max 60A current and 6000mAh

 

[riba2233]

Oh hi Tumich Are you still selling cells?

The 60P?
It’s certainly not a true continuous 60A rating but it can be run at that level until its temp limit is hit.

 

[DPR]

DCIR is 11.5mOhm

Under what conditions? Charge/discharge, current, and what pulse duration?

 

[belllfador]

Under what conditions? Charge/discharge, current, and what pulse duration?

Discharge, 3A, 10s pulse, 25*C.

 

[BlueSwordM]

Yep. The longer the discharge, the higher the IR.

Attatched a batch of 40 units of Linkdata 60P, for now just measured AC IR and mass, check it:



Average ac ir: 4,25 mOhms (1khz measured 4 point)
Average mass: 69,55 gr

If you want some special test I could do it, for now I will test 0.2C capacity, qOCV, 30A CC discharge till 2,6V...

Thanks for the data. Could you do a discharge test and temperature graph according to different current values (for exemple 15A, 20A, 25, 30, 35, 40) down to 2.5V ?

This way, we can compare it with other cells that Mooch has tested like the 50XG

Uh, Reliance's website is not available anymore

It points straight to a 404.

This isn't good...

Huh, are they going under or what? They're supposed to be at AABC Europe next week.
E. Website seems fine to me? It's this one right

Ah, it seems they may have a new website that hasn't really been indexed yet.

My Patreon supporters saw the prelim test results a while ago but the full test report for the 60P goes public this week.

No doubt! I will be uploading the tests done to these Linkdata 60P, also Mooch has done tests on his Patreon and I will be personally subscribing to it for seeing the tests compared to new Reliance RS60...

Oh my, I didn't notice, but this website has been heavily made with LLMs, I can tell.
I much preferred the old website

 

[Elios.pk]

Does someone has the datasheet of the Linkdata 60P ? I'm struggling to find it and find their website other than the Alibaba listings

Yeah it's so laggy

Btw I see you are good with datasheets, are there any chances you can find a Murata VX40 datasheet

Thanks, I didn't check in a while
