^^^ what about the 4450 pack being able to supply higher current, and being able to supply full power to the motor? perhaps the 2600 couldn't supply the amps?
The buggy draw about 1250 watts peak. At 22.2 volts that's 56 Amps.
The 2600 mAh pack is a 25/50C pack so my peaks are well under the 65A constant rating.
