Batteries 10s3p pack from china

So I was just browsing online looking for a 10s3p battery pack we could use for esk8 and I stumbled upon this:

Could we use this for our boards?

Yep, as long as you get them to change the BMS to a higher rated one, which from their description they can do.

As long as you are ok with 30a output.

i would not reccomend those batteries

I guess they skimp on the nickel strip, one layer most likely isnt going to cut it for esk8. I would go minimun 40-45A, but hey if you are a slow rider 30A may be ok.
