Yes, all batteries were fully charged (around 13v). However, we had one battery that was not holding a charge, even without running any motors, compressor, anything, the voltage was gradually dropping (0.1v per 4-5 secs). But our other battery was working fine, and that was the one we could not go up the ramp with.

All compnents had been run many, many times and were fully functional. Our drive was working as it normally would, but it was not getting the torque it needed to get up the ramp.

Also, in case it helps, we were running our drive on chips and worm gears. We also have a drill in the rear, but that was not being used when testing up the ramp, and was often not plugged in during matches, and we were still losing power.
