Regulated 9V Power
Provides regulated 9 V DC output with up to 15.3 W short-term peak power for compatible motorized building block devices.
For detailed motor-current references, configuration selection and high-load guidance, see the FynoriX1511 Engineering Guide.
High Energy for Its Size
4800 mWh high capacity, delivering up to 30% more energy than same-size cells for longer-lasting power.
InfiLinX Capacity Expansion
In the current FynoriX1511 configuration, connect two or more energy modules through InfiLinX to increase total stored energy and extend operating time. InfiLinX is part of a broader modular connection system and does not increase the peak current available from a single PF output.
FynoriX1511 Quick Engineering Guide
1. An Independent Energy Module
FynoriX1511 was designed as the smallest independent energy unit in the system. It provides regulated 9 V power but does not control motor direction or speed.
Use the following system structure:
FynoriX1511 → Switch / Receiver / Controller → Motor or Electrical Load
The battery provides power, the controller controls, and the motor creates movement. Separating these functions allows the thin energy module to be positioned wherever suitable space is available.
The battery should adapt to the model—not the model to the battery.
Power Functions compatibility is only the starting point. FynoriX1511 is intended to become the energy foundation of a future modular electrical ecosystem.
2. Important Power-Off Behaviour
When FynoriX1511 is switched off, its regulated 9 V circuit is disabled, but the output is not completely electrically isolated. A low voltage may remain at the PF output.
A motor connected directly to the energy module may therefore continue turning slowly after it is switched off. This is a normal product characteristic.
For predictable start and stop control, always connect a compatible PF switch, receiver or controller between FynoriX1511 and the motor.
Disconnect the electrical load before storage, transport, charging or work on the model.
3. Choose the Right Configuration
Application requirement
Recommended configuration
Purpose
Compact or standard model
Single FynoriX1511
Recommended starting point for most light- and medium-load applications
Longer operating time
InfiLinX Capacity Expansion
Increases total stored energy and extends runtime
Heavy startup or several motors starting together
Multi-Battery Stacked PF Output
Provides greater available power for short-duration startup demand
InfiLinX Capacity Expansion
Use InfiLinX when one module provides sufficient performance but longer runtime is required.
For two modules:
P3 OUT → P2 IN P2 OUT → P1 IN P1 PF Output → Switch / Receiver / Controller → Motor or Electrical Load
For additional modules, continue the chain toward P1.
InfiLinX increases total stored energy and runtime. The main PF output remains regulated at 9 V, and the peak current available from a single PF output does not increase.
Multi-Battery Stacked PF Output
For models with greater startup demand, connect each FynoriX1511 using its own PF Output Cable and stack the PF connectors directly together. Connect the compatible switch, receiver or controller after the stacked connection.
The output remains regulated at 9 V. Available current or power should not be assumed to increase linearly with the number of connected modules.
These configurations serve different purposes:
Use InfiLinX for more capacity and longer runtime.
Use Stacked PF Output for greater short-duration startup support.

🔧 Requires model-specific evaluation
Motor type alone does not determine the required configuration. Vehicle weight, gearing, friction, drivetrain efficiency and simultaneous motor startup can substantially change electrical demand.
Begin with one fully charged FynoriX1511 and test the completed model under realistic operating conditions. Correct unnecessary drivetrain resistance before adding more energy modules.
5. Charging, Protection and Safety
Before charging or connecting multiple modules:
switch off and disconnect all modules;
charge each module separately;
use modules with a similar state of charge;
inspect all cables and connectors;
disconnect the complete InfiLinX chain before charging.
If protection interrupts the output:
Connect FynoriX1511 to a charger for approximately one second to reset the protection circuit.
Fully charge the module.
Check the drivetrain for binding, excessive resistance or an unsuitable gear ratio.
Do not repeatedly restart a blocked or stalled motor.
Never combine FynoriX1511 with a traditional PF battery box, USB-C to PF Adapter, external power supply or another powered device on the same PF circuit.
Do not open, modify or use a damaged FynoriX1511 module or cable.

Q: What is FynoriX1511?
A: FynoriX1511 is a compact rechargeable 9 V modular energy module designed for PF-compatible Technic and MOC systems. Its slim 5 × 11 panel-compatible footprint allows it to be positioned in space-constrained models.
Q: What output voltage does FynoriX1511 provide?
A: It provides regulated 9V DC output.
Q: Why can a motor continue turning slowly after FynoriX1511 is switched off?
A: The power button disables the regulated 9V circuit, but it does not completely electrically isolate the internal cell from the PF output. Because of the customised cell and circuit architecture, a low-voltage output remains at the connector. A motor connected directly to FynoriX1511 may therefore continue turning slowly. This is a normal product characteristic rather than a fault. For normal operation, connect FynoriX1511 to a compatible PF switch, receiver or controller first, and connect the motor after that controlled component.
Q: What is the battery capacity?
A: FynoriX1511 has a 4800mWh internal rechargeable battery.
Q: Why does the indicator remain red after I connect the charger?
A: If FynoriX1511 is switched on while the battery level is low, the red low-battery indication takes priority over the blue charging indication. The module may still be charging, and the indicator will turn green when fully charged. Switch off FynoriX1511 and disconnect the load before charging to obtain the normal blue charging indication.
Q: What is the maximum output current?
A: The maximum output current is up to 1.7A short-term peak. Avoid stalled motors, overloaded drivetrains, or continuous operation near the peak current limit.
Q: Why are some measured motor-current peaks higher than the 1.7 A output rating of FynoriX1511?
A: The test values represent the current demanded by specific motors during a simulated high-resistance startup condition. They do not represent current continuously supplied by one FynoriX1511. If the demand exceeds the short-term operating range of the selected configuration, the protection system may interrupt the output. Actual demand depends on the complete mechanical system.
Q: Why may protection activate during motor startup?
A: In some applications, high startup resistance may briefly place a motor close to stall. Its instantaneous current can then rise substantially above the normal running level. If the demand exceeds the short-term operating range of the selected configuration, the internal protection system may interrupt the output as intended.
Q: How much does FynoriX1511 weigh?
A: It weighs approximately 35g, making it suitable for lightweight Technic and MOC builds.
Q: How thick is FynoriX1511?
A: It is approximately 7.8mm thick, which is about 1 stud thick.
Q: Can multiple FynoriX1511 units be used together?
A: Yes. FynoriX1511 supports two different multi-module power configurations. When used with FynoriX1511, InfiLinX Capacity Expansion increases total stored energy and operating time. Multi-Battery Stacked PF Output allows multiple FynoriX1511 modules to contribute to the same PF circuit when greater short-duration startup power is required. These configurations serve different purposes.
Q: Is InfiLinX only a battery-capacity expansion connection?
A: No. InfiLinX is a modular interconnection interface for compatible components within the expanding CONCEPTBRICK electrical ecosystem. Depending on the connected modules and configuration, it may carry power or control signals, while future compatible applications may also support data transmission. When used with FynoriX1511, its current function is to increase total battery capacity and extend runtime. InfiLinX is not a charging interface.
Q: Does FynoriX1511 control motor direction?
A: No. The power button enables or disables the regulated 9V output circuit, but it does not control motor direction or speed and does not provide complete electrical isolation at the PF output. Normal start, stop, direction and speed control should be managed by a compatible external switch, receiver or controller.
Q: What is the difference between FynoriX1511 and the USB-C to PF Adapter?
A: FynoriX1511 is an onboard rechargeable 9 V modular energy module designed to be built into a model. The USB-C to PF Adapter is an external power adapter used with a compatible USB-C PD power source.
Q: What models is FynoriX1511 best for?
A: It is best for compact Technic MOCs, RC-style vehicles, crawlers, robots, motorized display models, and builds where a traditional battery box is too large or difficult to access.
Q: Can FynoriX1511 power an SBrick?
A: Yes. FynoriX1511 provides regulated 9V power through its Power Functions-compatible output, making it suitable as an independent energy module for existing SBrick systems. Connect the system as follows:
FynoriX1511 → SBrick → Motor or Electrical Load
Available system current remains limited by the output capability of the connected FynoriX1511 configuration and the electrical demand of the complete model.
