This is a high current battery, how high varies with where I look. With the battery I got a note saying 30A, as can be seen above Keeppower gives it a higher rating on their website. I did also find a datasheet with discharge curves up to 20A.

Very good tracking between the cells. Looking at these curves I would prefer to stay at 20A or below in current.
