The packs are 5S 3650mAh 35C ones. I thought about going for the slightly higher capacity 4300mAh packs since they were only a few quid more expensive but with the bigger 775 motors this year, internal space is tight and the smaller size of the 3650mAh packs are better suited to the robot. Capacity shouldn't be a problem as the old packs were only 2200mAh and I got about 4 minutes out of them.

Found out that the Banebots order arrived today so it'll be all systems go next weekend
