36v 12800mah help to upgrade!

[asterix68]

Hello everyone, I recovered a 36v 12.8A battery from electrical waste, i.e. 3200mah cells. https://octopart.com/fr/datasheet/inr18650-mh1-lg+chem-118692561.

3200mah = 2x more 1600mah.
For my bike, I'd like to add amps. At least 10 more amps, to get 36V ~22-25 amps. I currently have recovered cells:
Basically 2500mAh
2200mAh
2000mAh

with your packbuilder, I tried: with used ~2500mah cell

Total Capacity 14439 mAh
Divergence (from the average pack capacity) -133 mAh
Deviation (between the capacity of cells in the pack) 53 mAh

So my question, is on Battery ampere limit.
My battery make 12800mah.
and here i should upgrade in parallel to 14439mah so difference between 1539mah.
This 1539mah more ampere in battery, are don't this ampere too large capacity in connect parallel?

The last capacity, was false, only in 4S 5P, because don't enough cells.

yes i!!!!!!!!!!!!!!!!! i am the best!!! youpiiiiiiiiiiiiiiii tralala!!!!!!!!! (for give me for my joy)
Summary

Each parallel pack once connected together will create a battery with these characteristics.
Voltage (3.6 nominal) 36V Amp Hours 12.979 Ah Watt Hours 467.24399999999997 Wh

and this are now 10s 5P cells.
Parallel Pack 0

4 1951
5 1926
Total Capacity 13190 mAh
Divergence (from the average pack capacity) -195 mAh
Deviation (between the capacity of cells in the pack) 269 mAh

So i think +390 mAh, is don't excessive as battery difference to future connection with 12800mAh in parallel.

So i don't touch on original battery, because the 10S BMS which are connected on 10 cells.
and this added amperage should connect with XT60 connector in Parallel with Main battery.

but here the 9 other parallel....

and i have 9 other cells which are unused. But i need Ten not nine Cells
and here all was based to reach 12800 mAh.

You bought 40 used LG MH1 cells, originally rated at 3200 mah and you want to mix them into a 10S-6P ebike battery, WHat is their capacity now? If it is under 2600 mah, I could call them worn out and too old.
