I've run 7 cycles thru on my first time out at the track and the car was great. The batteries, also great! I was averaging 245mah/min running hard and braking hard. While I was only doing 10min runs to get mileage the math works out as 245/5300=21.6min Thats more than enough for E buggy mains. Even with a bad mileage run of 280 and following the 80/20 run down rule I still got 15min in the bag.
