BAK 18650 2600 mAh cells for battery build?

Hi All,
I have been lurking and reading for a while and currently have purchased

  1. Waterproof motor FS65161 120KV
  2. HGLRC-Flipsky High Current FSESC 200A 60V ESC base on VESC6

and at this stage of considering my options for battery builds. I am less concerned with maximum ride time and more concerned with ease of build, safety, and cost.

I came across a great bulk deal on new BAK 18650 2600 mAh grade A cells. I know they don’t have the high power density most here use, but they are cheap and have long life cycle. These also come with a 5a PCB on each cell.

Any reason not to use the cells for a efoil battery build. Any helpful feedback would be deeply appreciated.

Thanks in advance
