LiPo batteries basics

So using the Waterwolf battery as an example regarding typical capacity & voltage.

And 8 EUR Lipos like following:

Would this mean?

50,4 V divided by 3,7 V = 14 Lipos in series

(Wh / V) * 1000 = mAh = 1510 / 50,4 V * 1000 = 29.950 mAh

29.950 mAh / 170 mAh = 176 Limos in parallel

176 (parallel) * 14 (series) = 2.464 Lipos ?

Even for 4 EUR a piece that would be 10.000 EUR for a battery pack?

This seems wrong. Where is the mistake?
