EZGO TXT BigBattery HSKY, Alltrax conversion, 36-48 conversion results

[superfan86]

I know a lot of folks have been asking about the performance gains from different combos, so I wanted to add another thread for the greater good.

05 EZGO TXT PDS. Stock AMD 36v motor. Factory lift on 22" tires

Stage 1:
Freedom Controller
RoyPow 105 36v

Speed remained the same (20 mph tops). Acceleration and handling excellent. Significant increase in acceleration and torque

Night and day difference between lead acid and likely anyone ever needs.

Stage 2:
Alltrax 400 controller (450 amp peak output configured)
Lead Acid 36v
Comparable acceleration performance to Stage 1, which was surprising. Battery fatigued after about a mile, but still remained better than "stock"
Top Speed increased to 25, but took awhile to get there. Realistic top speed is 22-23.


Stage 3:
Alltrax 400 controller (450 amp peak output configured)
BigBattery HSKY 103 48v (350 amp peak output)
Obviously a huge difference.
Cart does wheelies if floored from a stop (battery is in front tray to help). Top speed 31 MPH and no trouble getting there. 0-25 without any effort and nearly instant. Realistic top speed is about 28. Torque monster and weight reduction makes you forget that curbs exist.
Stock brakes are no longer adequate. YOU NEED TO UPGRADE NOW

Please forgive the wiring mess. Terminal blocks are arriving today...
