EVFREAKS 72V 55Ah Performance Battery
Hand-built in Germany, this 72V 55Ah performance battery
With our greatest 72V battery upgrade, you can unlock the Sur-Ron Light Bee's full potential. This battery was developed for riders who require a superior level of speed, reliability, and durability. It is handcrafted in Germany using premium AA+ grade Samsung 50S or Molicel P42B cells.
Even in the most challenging riding conditions, it guarantees minimal voltage sag and steady performance thanks to its massive 32 kW peak power output and industry-leading thermal stability.
We rely on full-size pure nickel sheet conductors for our construction rather than nickel strips. This outperforms standard builds in terms of long-term durability and current delivery.
Performance
Expect up to 50% to 100% more range depending on your ride style, weight, terrain, and gearing. Minimal voltage sag ensures sustained performance at high loads, making this pack ideal for racing, high-speed trail riding, or aggressive torque-hungry setups.
In addition this battery offers amazing flexibility for custom builds and advanced tuning, and it is also totally compatible with other hot high-performance controllers such as the Torp TC500, EMBX, and Nucular 24F.
