The Ultra Bee is a big bike that eats batteries on long rides. Our Ultra Bee battery upgrade is a high-capacity custom pack that fits the Sur-Ron Ultra Bee, matched to your controller. These are Fast E batteries, built to spec for us and fitted and supported by our team on the Sunshine Coast, QLD. We quote every job, so you’ll get a price for your exact build.
Who it suits
- Ultra Bee owners chasing more range than the stock battery (see the official Ultra Bee specs)
- Riders running an aftermarket controller such as a VTB or Ventus unit
- Owners with a failed BMS or battery who want a replacement pack
Ultra Bee battery upgrade builds
Here are example builds we can quote. Each one is a starting point, and the pack can be changed to suit your bike.- 81.4V 70Ah, 340A, built for the Ultra Bee
- Other voltages and capacities to suit your controller and the space available
- Every Ultra Bee battery upgrade is matched to the current your controller draws
- Our packs use an ANT smart Bluetooth BMS, so you can monitor voltage and temperature in the ANT BMS app (iOS and Android).
- Cell options include EVE, Molicel and Samsung, depending on the build.
- Our packs use XT60 or XT90 connectors for charging and QS8 or QS10 for discharge. We can match your controller’s plug.
How the quote works
- Start a quote in the chat and pick Custom battery.
- Tell us the bike or application, voltage, capacity or range you want, controller, max continuous and peak current, connectors and quantity.
- Send photos and measurements (length, width, height) of the battery space, plus your postcode.
- We spec the build and come back with a quote and turnaround. We quote every job, so there are no set prices.
- Once you approve, the pack is built, then fitted at our workshop or sent to you by dangerous-goods road freight.
