The 96V Pegasus Battery That Turns Your SurRon Ultra Bee Into a 100HP Stark Varg Killer
If you’re chasing real performance from an electric dirt bike, battery voltage is everything. Torque, sustained power, throttle response, and top-end speed all start at the battery — and this 96V Pegasus high‑voltage battery system is built for riders who want more than stock, more than typical upgrades, and even more than what many factory race bikes deliver.
This is the battery setup designed to push modern e‑moto platforms like the SurRon Ultra Bee into an entirely different performance class — a true Stark Varg killer when paired with the right high‑voltage controller setup.
Built for Extreme Power, Not Casual Riding
The Pegasus 96V system is engineered around premium 21700 lithium cells with a massive 5,251Wh of energy and extreme current capability. With a rated discharge of 280A and up to 800A peak, this pack is designed to feed high‑power controllers without voltage sag — even under aggressive riding and racing conditions.
When paired with a properly configured Aetos controller, this battery system is capable of supporting up to 100 horsepower, putting it firmly above many factory electric motocross bikes.
For comparison (real‑world performance targets):
-
Stark Varg: ~80 hp (factory configuration)
-
Ultra Bee + Pegasus 96V + Aetos: up to 100 hp
More voltage means more speed, harder acceleration, and stronger power delivery across the entire RPM range.

Intelligent BMS With Live Display
At the core of the Pegasus system is a high‑current smart BMS designed to safely manage extreme power output while giving riders full visibility into battery health.
The integrated full‑color display provides real‑time data including:
-
State of charge (SOC)
-
Pack voltage and current
-
Individual cell balance data
-
MOSFET temperature
-
Cell temperature
This real‑time monitoring helps prevent unexpected cutoffs, allows quick diagnostics, and gives riders confidence when pushing the bike hard.
Pegasus High‑Output Charger Included
The system is paired with the Pegasus PGS9656 high‑voltage charger, designed specifically for large 96V battery platforms.
Charger Specs:
-
DC Output: 109V / 15A
-
AC Input: 110V
-
Frequency: 50–60Hz
This charger delivers fast, consistent charging while maintaining proper cell balance and long‑term battery health. Ideal for shop use, track days, or home garages.
Stable Voltage = Faster Bike
One of the biggest advantages of a high‑voltage system is voltage stability under load. Unlike lower‑voltage packs that sag during hard acceleration, the Pegasus 96V system maintains consistent output — which translates directly to:
-
Faster acceleration
-
Higher sustained top speed
-
Stronger mid‑range pull
-
Reduced heat stress on electronics
When combined with a high‑power controller like the Aetos, this battery allows the Ultra Bee platform to perform at a level that rivals — and in some cases exceeds — larger factory electric motocross bikes.
Rugged, Sealed, Race‑Ready
The Pegasus battery enclosure is fully sealed to IP67 standards, protecting internal components from dust, water, and debris. Shock‑isolated internals and a reinforced housing ensure reliability in aggressive off‑road and race environments.
Rain, mud, vibration, and hard riding won’t compromise performance.

FAQ: Pegasus 96V Battery & Ultra Bee Performance
Is the Pegasus 96V Battery the best upgrade for the SurRon Ultra Bee?
Yes. The Pegasus 96V battery is one of the highest-performance battery upgrades available for the SurRon Ultra Bee. With significantly higher voltage and current capability than stock, it enables massive gains in speed, acceleration, and sustained power when paired with a compatible high-voltage controller.
Is the Pegasus 96V battery faster than a Stark Varg?
In properly configured builds, Ultra Bee setups running the Pegasus 96V battery with an Aetos controller can exceed the factory power output of a Stark Varg. While the Stark Varg is rated around 80 horsepower, Pegasus 96V builds are capable of supporting up to 100 horsepower, giving them a clear performance advantage.
How much power does the Pegasus 96V battery support?
The Pegasus 96V High-Voltage Battery System supports a rated discharge of 280A with 800A peak, making it suitable for extreme high-power e-moto builds. Power output ultimately depends on controller, motor, and tuning, but this battery is designed for the highest-performance applications on the market.
Can you install the Pegasus 96V battery under the stock Ultra Bee battery lid?
Yes. The Pegasus 96V battery uses the stock SurRon Ultra Bee battery lid, allowing for a clean, OEM-style installation while dramatically increasing performance.
