We recommend the BAC4000 for most people it's an ideal controller for the Surron! The BAC4000 is perfect for 60v batteries including a future upgrade to a higher amp-hour 60v for increased range. It is also compatible with 72v batteries. BAC8000 is recommended for those planning to ride at high continuous speeds (example: open throttle road riding) due to the fact that the BAC8000 will run cooler in these situations with its larger heat sink. The BAC8000 also has 800 phase amps vs 550 allowing higher power output for those wanting maximum power. Warning, max power can be uncontrollable and not a pleasant riding experience, for this reason EBMX provides multiple tunes with these controllers to tune the power output for your terrain. Custom tunes are available upon request.
It is strongly encourage to allow a SurRon Mod-Shop dealer install this for you. Charged Cycle works is located near Ogden, Utah and installations are available by appointment. Please email us at firstname.lastname@example.org for details.
If you are unable to provide your bike to a SurRon Mod Shop supplier, then you may install it yourself. Please view the installation video below and ensure you have the proper tools and are confident in your skills prior to ordering. This is a potentially dangerous upgrade process and not recommended for those without electrical experience.
WARNING: The battery bypass procedure is very dangerous, a mistake could cause a Lithium Ion fire (like all those Tesla Videos you have seen) or worse electrocution! This procedure should only be performed by a license electrician and Charged Cycle Works is not responsible for any damage or injuries or death caused by this procedure.
*Neither EBMX Pty Ltd, nor Charged Cycle Works, accepts liability for any DIY Battery bypasses or installations on our range of ASI and SurRon modifications. Although we supply fitting instructions with our kits, we do not recommend that you install the equipment yourself. If you purchase the kit to install yourself, you can contact us if you have a problem and arrange for remote support at a rate of $75 USD per hour.
