- Lithium Ion battery duration: 500km/month - 1500km, 1000km/month - 1800km, 2000km/month - 2000km
- Water proof to 1m for 30 minutes (IP67 Rated)
- Operational temperature: -4F to 140F
- Charging temperature: 32F to 113F
- The V4 power unit features 10% better battery duration
- 16.6mm diameter for easy seatpost installation
- 259mm length
With its new design as well as a plethora of useful and innovative new technologies, this small component improves the EPS experience in a big way. Improved integration, facilitated and nofuss charging, improved led diagnostics and wireless technology that allows for increased interaction with the groupset are just a few of the improvements housed in its tiny structure.

- DTI: Digital Tech Intelligence
Enclosed and protected in the Power Unit and interface, "Digital Tech Intelligence" transmits, receives and processes data thousands of times a second.
An electronic brain which instantaneously synchronises all the functions requested by the rider. With just a simple click of the controls, D.T.I transmits the corresponding signal instantly, accurately and reliably to the rear or front derailleur, for levels of performance and control feel never experienced before with a conventional drivetrain.
But as well as all this, the D.T.I. system also monitors the entire drivetrain and each of its components, continuously checking battery level and functionality, and checking that the rear and front derailleur are working correctly.
- Zero Settings
The procedures to reset the rear derailleur and derailleur to zero are essential for the system to function.
These procedures allow the system to learn the reference positions of the chain on the sprockets and chainrings, which will be used to calculate the positions that need to be used in all operating conditions.
During the resetting to zero phase the movements of the rear derailleur and derailleur occur continuously, and not through set movements as during adjustment, and they depend on the pressure time of levers 2 and 3.
The position can be changed by even just a hundredth.
The Power Unit was originally modified to be mounted internally both to protect it from the elements as well as to confer an aerodynamic advantage to the overall build. With the advent of increasingly aerodynamic frames and with them even slimmer tube forms Campagnolo has produced an even more advanced version of its power unit ; the V4.
This new version of the internal power unit maintains all of the previous characteristics and technologies that derive from the V3 such as a vibration absorbing outer material, ultrasonic seals providing a waterproof construction and industry leading autonomy and house them all in a slimmer, more versatile package.
This new structure opens up the possibilities for internal mounting not only in the most aerodynamic framesets with very slim tube designs but also gives a greater deal of flexibility with regards to placement within the frameset. Thanks to this new slim structure the EPS advantage is now available for all frames, no matter which make or model you choose.

- Waterproof - IP 67
Electronic
The Campagnolo EPS electronic drivetrain complies with IP67 international standards.
This means that the system is able to protect its electronic components from dust and liquid infiltration.
In order to achieve the IP67 classification, all the electronic components of the EPS system underwent a series of tests, which proved their ability to function perfectly under one meter of water for at least 30 minutes.
- On Board Diagnostic
Electronic
The EPS system is capable of automatically detecting a whole range of malfunctions.
If a malfunction is detected, the EPS system turns on an RGB led located on the power unit.
Depending on the area where the malfunction has been detected the led takes on different colours, as per the table below.
Being that in some situations the cause of the malfunction making the led light up on the power unit may be temporary, a number of operations are recommended to the end user depending on the colour of the light that appears on the PowerUnit.
Features & Benefits
- New Shape:
V3 Power Unit integrates battery pack and electronic intelligence board within a sealed unit with a total length of 232 mm and a diameter of only 16,6 mm.
- Seatpost mount compatible:
the reduced diameter (16,6 mm) allows the V4 Power Unit to be mounted within the seatpost, by using one of the two available adapters (for ø 27,2 and ø 31,6 mm), thus reducing assembly time.
- Specially developed internal casing designed to makes the system 100% waterproof:
for maximum protection of the battery and electronic components on even the worst road surfaces.
- DTI Digital Tech Intelligence:
the digital brain of the EPSTM drivetrain. DTITM monitors and checks the battery, transmits and receives signals to and from the interface and controls and monitors the functions of the rear and front derailleur.
- Seat tube/ Down tube adaptor mount:
allows the Power Unit V4 to be mounted in either the down tube or seat tube by taking advantage of the water bottle cage mounts.We love this Campagnolo DTI EPS V4 Interface.
- Riding Settings
Electronic
The client can adjust the reference position of the rear derailleur and/or derailleur using the adjustment procedure known as Riding Setting.
The adjustment of the rear derailleur is designed especially in case you change the wheel for one with a set of sprockets that are positioned differently with respect to the drop out.
It is possible to start the procedure for either the rear derailleur or the derailleur from any chainring.
Every time either keys 2 or 3 is pressed, the system performs a set displacement of 0.25 mm if you act on the rear derailleur, and approximately 0.1 mm if you act on the derailleur.
When you have completed the adjustment phase, the system will correct the established positions of all chainrings based on the new settings.
