I want to find out constant amps of this cell. This pack is from new Honda. Attached pic ha some infor about cells but I'm interested in constant current particularly.

You cannot rely on published current specs even new but secondhand forget it.

It's not an objective metric anyway, very much how you define your test parameters

Test yourself define your time periods and measure based on heat rise, voltage drop.

Max continuous discharge rate?
What PHEV is this battery pack from?
NMC batteries typically have This info a datasheet
max continuous discharge rate
max pulse discharge rate expressed as __A≤ seconds
max charge rate
often times the datasheets are kept confidential only Panasonic and Honda would have access to the reports.

Yes to first question. Regarding second, - it is from some new Honda like I mentioned initially but don't know exact car model. You are correct, they do keep datasheet confidentiality appearantly. But now their battery is on the table like most of them and will end up in ebikes and probably scooters, it's over for their secrets.

Samsung SDI 94 Ah battery cell full specifications - 🔋PushEVs this one doesn't give max continuous discharge least that I could find. max 5s, max 30s rates
The Honda cell datasheet I could not find.
Modern Panasonic prismatic battery cells - 🔋PushEVs but this only gives basic info
  • Manufacturer: Panasonic
  • Capacity: 51 Ah
  • Nominal voltage: 3,7 V
  • Energy: 188,7 Wh
  • Form factor: PHEV2
  • Chemistry: NCM 622
Hope this helps

That's the info pop up right away when I tried to look for info about these cells and it's in the initial post , but that's all I could find. I specifically need to find constant discharge current information, preferably some graphs, datasheets, usual stuff. Few sources mentioned 3C but it it's not confirmed by any testing so far, nevertheless some cells already about to be put inside ebikes with 20s peak 10kw+ draw.

Some info:

I'm look at that pdf you attached. And comparing partial specs I got about my cells with GL65 specs in pdf datasheet link you sent. Considering such numbers 51AH 188.7Wh 854g and GL65, 65AH , 219 Wh/kg, 1120g (numbers from link/pdf). Looks very similar cells but in different form, packaging and capacity. If only chemistry determines constant discharge than mine would be 153A constant discharge.
