- Can easily hot swap in seconds between different batteries with the app, for example easily swap between 60 volt and 72 volt batteries and back down.

The safest BAC mounting system in the market. Our custom programming and harness avoids criss crossing the high temperature controller and motor phase wires with the custom harness and thus avoids the potential of any short circuits. All other kit providers leave large gaps after the installation, crossing harness with phase wires and creating the potential for an electrical short circuit.

Frequently Asked Questions


Will installing this kit void my warranty?

Yes, installing this kit would (we suggest) void the warranty on your SurRon Light Bee Battery, if it is still under a warranty period.

Which should I get the BAC4000 or the BAC8000?

The BAC4000 is perfect for the 60v SurRon BMS Bypassed upgrade. The BAC8000 60v Upgrade is specifically designed for people who plan to invest in a 72v Battery, down the track, perhaps after their 60v battery dies. This means – that they do not have to upgrade their ASI controller again when they upgrade batteries, and all they need to pay for is an additional 72 V custom tune to receive the Stage 2 Upgrade Kit.

Can I install this kit myself?

You can purchase the kit without installation however without a battery bypass, upgrading the controller to an ASI Controller alone will not significantly increase your power. eBike Mod Shed is not responsible for any damage you do to your bike due to incorrect installation. If you are going to install it yourself, we recommend getting at least the battery bypass done by a professional.

Will this decrease the life of my battery?

Yes, installing this upgrade kit will decrease the life of your battery. It depends on a lot of factors exactly how much this will decrease the life of your battery, e.g. age and health of the battery before the bypass, correct maintenance and care for the battery after the bypass, etc.

How much power can I expect to get from this upgrade?

We have a stable tune which gives you 7.2kW on stock bypassed battery. This is a (75-90%) increase in power. With this upgrade you get significantly more torque and acceleration at the rear wheel, and your max top speed will depend on the rear sprocket size you are running (i.e. 42-62 teeth are possible)


* eBike Mod Shed Limited does not accept liability for any DIY Battery bypasses or installations on any of our ASI controller upgrades for SurRon’s or Talaria’s. We recommend that you get our kits installed at our workshop by professional.
