Ventus Ultra Bee Pegasus Battery 96V 56Ah | by Ventus | For Sur-Ron Ultra Bee E-Moto

What It Is

The Ventus Ultra Bee Pegasus Battery (96V 56Ah) is the key ingredient for riders chasing serious power on the Ultra Bee platform. If your goal is a true high-output build, this pack is the foundation. The big milestone everyone talks about, that 100hp-level output, comes from pairing this battery with the Ryuga motor and the VTB Ateos controller in a properly configured setup.

Why It Stands Out

This pack is built for extreme current delivery without the annoying voltage sag that kills top-end and makes hard pulls feel soft. You get a high-current architecture for sustained high-load riding, a sealed IP67 enclosure for real off-road use, and an intelligent BMS with a full-color display so you can actually see what the battery is doing in real time. It’s a performance-focused system that’s designed to stay consistent under abuse, not just look good on a spec sheet.

Technical Specifications

Battery Configuration: 26S

Intelligent BMS and Real-Time Monitoring

At the core is a high-current smart BMS designed to manage extreme power output safely and efficiently. The integrated full-color display gives live feedback so you can monitor health, catch problems early, and avoid power cutoffs when you’re pushing hard.

Pegasus High-Output Charger Included

Included is the Pegasus PGS9656 portable charger, purpose-built for high-voltage battery platforms. It’s a simple plug-and-play charger for shop, track, or garage use, designed for fast, consistent charging while supporting long-term pack health and cell balance.

Charger Specs

Output (DC): 109V / 15A
Input (AC): 110V
Frequency: 50–60Hz
Model: PGS9656

Built for Extreme Power Delivery

High-current architecture supports sustained high-load riding
Stable voltage output helps minimize sag under hard acceleration
Designed for advanced controllers and high-power motor systems
Ideal for race builds, high-voltage conversions, and performance-focused riders

Rugged, Sealed Construction

The enclosure is sealed to IP67 standards to protect internals from dust, moisture, and debris. With shock-isolated internals and a reinforced housing, it’s built to survive aggressive off-road use and race environments where normal packs get punished.

Designed for Confidence

Engineered and assembled by VTB International with strict quality control. This is for riders who want big power while still prioritizing safety, durability, and serviceability.

Installation and Compatibility Notice

This 96V battery requires the OEM 12V converter to be unplugged or removed before installation. The stock 12V system is not compatible with 96V operation and may damage the converter and other electrical components if left connected.

If you want to retain 12V functionality, use an aftermarket 12V converter designed for high-voltage systems. Proper system configuration is required before powering on the bike.

Who This Battery Is For

If you’re building a serious Ultra Bee, this pack is the right move. Premium 21700 lithium cells, massive current capability, stable voltage under load, and intelligent monitoring make it a legit foundation for high-power setups. Pair it with the right controller and motor and you get a bike that pulls hard, stays consistent, and gives you real data to back it up.

Race and track riders who need repeatable power without cutoffs
High-voltage conversion builders running advanced controllers and motors
Performance-focused riders who want big output with real monitoring and durability
