This sensor hub is to connect two PL-xxx current sensors in parallel. The current of both sensors will be summarized and passed to the FC. The voltage measurement of the LiPo packs will be collected from both sensors and passed through the Hub to the FC.

The main purpose of this hub is to replace existing protection circuits (like an ideal diode) and to monitor, that both paralleled LiPo’s supply the same current to the system.

Since we monitor the current of both batteries, we will find out very early when a LiPo starts to fail… before it is too late.

If the difference in current is larger than +/- 15%, the Alarm output will be always ON to indicate the fault… the pilot should immediately land and check the batteries.

Improved design compared to HS - Sensor Hub "V1":

  • No more DF13 connectors, all connectors are Molex Clik-Mate / 1.25mm
  • Dual color LED (red/green) for status of the current sensors.
  • Delivery inclusive CFK enclosure

To set up a complete system you would need:

1x PL Sensor Hub X2 "V2"

2x Current sensor board:

     2x PL-050  =  2 x   50A  = 0-100A Total

     2x PL-100  =  2 x 100A  = 0-200A Total

     2x PL-200 or PL-200/8  =  2 x 200A  = 0-400A Total

1x PL - BEC (1x, 2x or 3x) or Power-Cube 1, 2, 3 or 4 "V2"

Scope of delivery:

1x PL Sensor Hub X2 "V2"

1x CFK enclosure

2x Sensor cable / Molex 1.25mm - 4p / L = 150mm

1x Alarm output cable / Molex 1.25mm - 3p / L = 100mm

The PL - Sensor Hub X2 can be screwed down to the main frame, by removing the 4 bottom M3 screws and drilling holes into the frame. Then reinstall the screws trough the frame.
Size: 42mm x 34mm x 10mm
