3ah in 3 minutes means a continue draw of 60amps. But fights ain't a continous draw, it's peakload after peakload.
And sla's are very inefficient in that kind application.
That's why a robot that blows up 9ah sla batteries in about every fight can perfectly work fine on 5000mAh 30c LiPo.
Also the reason why "historical" 12 to 17ah sla of normal quality was used in heavies on tv.
I know where my money goes to.
