How do you get 48v 15Ah capacity out of the shark battery pack when each cell is only 3v 1500mAh. By my math you would need 16S and 10P, but the Shark pack doesn't hold 160 18650 cells.

The very largest shark battery case (which is larger than the one shown in the picture) only holds 91 18650 cells max.

Maybe you could you cram 15 or 16 pouch cells in one and do 15s1p?

Here are the cells Hakadi lists on their website:

You can't buy this yet, you can make a donation and hope they get manufacturing going. If it doesn't work out, they will donate your money to a 'green clean donation', whatever that is.
From the indiegogo page:

What we need for full production:

• We need supporters just like you to spread the word!
• We prefer funding from people like you!
• We have confirmed all our testing is correct and ready for production!
• If we fail our funds would be used for a green clean donation!

I do not trust Engelhorn tech to assemble a battery at this point.

Remember Engelhorn tech is just a battery pack assembler (like EM3EV).

If I calculate the volume of a jumbo shark pack like:

52V 14.5Ah Jumbo Shark Ebike Battery (2900 18560 Cells)

Best deals on 48V Ebike Batteries. This high capacity 48V 17.5Ah Jumbo Shark Ebike Battery with premium Samsung 35E 18650 cells is designed to give you longer range and works with our Bafang ebike conversion kits and should be compatible with most 48 volt ebikes or ebike motor kits.

Then divide by the volume of this 36.5Ah pouch:

Then multiply by 36.5Ah, I do get suspiciously close to 15Ah:
14.021608643457

I've never had a shark pack before, but I do have a lithium ion equivalent of their "48v 15 ah Battery Pack Trad" option and it's something like 22Ah with Samsung 35E cells:


So it does feel like they are promising less than the lithium ion equivalents, and inline with general volume of a pouch cell solution.
