The 72 V 40 Ah Performance battery is engineered for the Dualtron Thunder and Thunder 2 with upgraded controllers, or for riders tired of power cut-offs under hard acceleration. Its Samsung 40T or Molicel P42A cells deliver up to 400 A peak, where the stock battery maxes out at 140 A: your controller finally receives the current it demands, voltage sag on steep inclines is eliminated, and your dialed-in power is truly unleashed.
Key Benefits
- No more cut-offs or voltage sag during hard accelerations or steep climbs.
- Discharge current up to 400 A peak (vs. 140 A stock): plenty of headroom to crank up single or dual controller power.
- Smart BMS: monitor power consumption, state of charge, and individual cell group temperatures directly from your smartphone via Bluetooth.
- Manual cell balancing straight from the app.
- Fast charger compatible for rapid turnaround times.

Who Is It For?
Riders running stock controllers with factory settings do not need a Performance pack: a high-capacity Long Range battery delivers the same utility at a lower cost. The Performance pack truly shines with upgraded or reprogrammed controllers (VESC, raised battery current limits), competitive track use, or heavier riders pushing a high-output machine.

Frequently Asked Questions
Which app works with the Bluetooth BMS?
The BMS connects to a free app available on Android and iOS; full setup instructions and app details are supplied with your order.
Samsung 40T vs. Molicel P42A: what is the difference?
Both are premium 21700 high-discharge cells offering identical performance; we assemble with either cell model depending on factory inventory, without any change in rated capacity or continuous output.
Can I use my stock charger?
Yes, provided the voltage matches. To take full advantage of fast charging, high-amperage fast chargers are available separately.
