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.

Based on the curves I see it looks to me more like 15 Amps is closer to optimum than anything above that. Things start to sag above 15 A.
