X8 Battery Kit – for up to eight batteries
This complete kit provides all the components and cables necessary to power your flight controller and other onboard equipment.
- 1x Sensor Hub X8
- Choose your power supply: 1x PL BEC or Power-Cube
- Choose your PL sensors: 50A, 100A, or 200A, in a quantity between 3 and 8 (all sensors connected to the X8 must have the same current rating)
- Choose your cables: if additional cables are required to connect to your flight controller, you will be prompted to add them.
Save compared to buying parts separately!
1. Powering the X8:
The Sensor Hub X8 can be powered by any PL BEC or any Power-Cube (4.95-5.05V).
Connect the special cable with 2x 4p and 2x 3p connectors as follows:
- 1st 4p -> PL BEC or Power-Cube
- 1st 3p -> X8 power port
- 2nd 3p -> X8 sensor 1 input
- 2nd 4p -> PL sensor 1
2. Connecting PL sensors:
Up to 8 PL sensors with the same current rating can be connected. Sensor 1 must always be connected.
3. Resetting the X8:
After an alarm (because of over or under current), a reset of the alarm can be performed by pressing the reset switch for a short time. An alarm output and external reset cable to make an external switch and alarm relay.
4. Status LED:
RED = Initialization, alarm active or rest switch pressed.
GREEN = Initialized and no active alarm.
5. Alarm LED or buzzer:
An alarm output and external reset cable is provided to make an external switch and/or alarm relay. Any LED or buzzer can be connected here (max. 1A).
Pin 3 = P -> The middle contact of the relays.
Pin 4 = NO (normal open)
Pin 5 = NC (normal closed)
6. External LCD/OLED display:
A standard 2×16 LCD or OLED display (4 bit data bus) can be connected to use as an external display (no backlight).
7. DIP switch:
|OFF||OFF||Internal and external display OFF|
|OFF||ON||Internal display ON / External display OFF|
|ON||OFF||Internal display OFF / External display ON|
|ON||ON||Internal and external display ON|
8. I2C connection:
Reserved for future use
9. PL sensor status indicator:
_ = Sensor not connected.
II = Sensor connected and current is within limits.
L = Current is at least 25% lower than average -> alarm relay triggers.
H = Current of this sensor is at least 25% higher than average -> alarm relay triggers.
10. Sensor summary:
The number of PL sensors is shown along with the configured current setting (50A, 100A, 200A, 400A).
11. Total current:
The total current measured by all sensors is shown.
12. Mission Planner setup:
The output voltage from the Sensor Hub X8 is always optimized to be 0.0-3.3V from 0A to full current on all sensors. This ensures that the full range of analog input is used to get the most accurate current readings as well as capacity consumption calculation. For example:
4 x 100A Sensors = 0.0V @ 0A and 3.3V @ 400A -> Amp/Volt value = 120
5 x 200A Sensors = 0.0V @ 0A and 3.3V @ 1000A -> Amp/Volt value = 300
8 x 200A Sensors = 0.0V @ 0A and 3.3V @ 1600A -> Amp/Volt value = 480
Standard values for Amp/Volt:
The Sensor Hub X8 can be either installed via double side tape, or screwed down to the main frame, by removing the four M3 screws and drilling holes into the frame. Then reinstall the screws trough the frame. The original screws will be too short, so please replace them with longer ones according to the thickness of your frame.
