What is shunt mod?

Shunt mods are modifications that can be done to an ebike controller to improve power delivery. This modification increases the voltage going through the battery, making it easier to ride longer distances and go faster. 

Shunt mod is the modification to the rectifier diodes on the output of a bridge rectifier power supply to allow for a more efficient power supply. 

The diodes in a bridge rectifier on the output of a power supply are usually arranged like an ‘H’ with the rectifiers on the left, center and right. These are usually referred to as a type 1 configuration. 

The diodes are designed in this way to allow the power supply to be able to rectify AC input for use with a PWM controller such as a PC Power Supply Unit.

There are many different types of shunt mods available, so it’s important to find one that suits your needs. 

To install a shunt mod, first remove the stock controller from your bike and replace it with the modified version. 

Once you have replaced the controller, simply connect it to the bike and start riding!

What Is SHUNT MOD Ebike Controller?

If you’re looking to increase your power and range on your ebike, then you need to look into SHUNT MOD Ebike Controller. This modification allows you to change the gear ratio, making it more comfortable and efficient. 

SHUNT MOD is an electronic bypass controller that works as a “Tesla style” electronic speed controller on regular bikes.  It is used to avoid the resistors or other speed limiters and time limiters found on ebike controller systems.  

Using the SHUNT MOD, you can power your motor at 100% of the rated input current, meaning you can use your full motor power continuously.  

The main benefit of this controller is that you can add more batteries without having to upgrade your controller and void your warranty.  

This way you can run more powerful motors and larger loads on a smaller and lighter battery pack, saving you money.  

Simply use a DC converter to convert your battery voltage to the voltage your original controller runs at.  The SHUNT MOD does the rest.

Plus, it gives you that extra boost you need to get where you’re going faster. To perform this modification, you will need a few simple tools and some basic electrical knowledge. 

Once you have completed the installation, your ebike will be ready to ride in no time!
