Hybrid battery architecture3
The FCPM is designed to work alongside a hybrid battery. Thishybrid battery
provides some key functions:
Peak power draw – When a UAV is ying the power draw varies very quickly as
the UAV brakes, accelerates, climbs etc. The FCPM is designed to run at constant
rated power. When the power draw of the UAV peaks, the hybrid battery provides
peak power. When the power draw of the UAV hits a trough, the battery is charged.
The supplied hybrid battery can provide peak power for three minutes before
requiring a recharge.
The current limit of the 650W FCPM is 50A. The 800W FCPM has a limit of 80A.
Emergency ight time – The battery acts as an emergency backup power source.
Ifa critical issue occurs with the FCPM, the battery will take over. Thestandard
supplied battery will deliver rated power for around two minutes.
It is also important to note that the output voltage of the FCPM is a constant
25V(6S). Unlike a typical battery, voltage does not drop gradually throughout
a run, so you must change the way you think about remaining fuel/ight time
(voltage dips to battery voltage during hybridisation and returns).

It is important to integrate the UART output of the FCPM into your UAV
ight controller or eet controller. This will monitor your fuel levels showing
how much fuel remains. It will also tell you if fuel is low or if a critical fault
has caused the fuel cell to fail and the emergency battery to take over.

4.5 Hydrogen connection
First time only – the hydrogen feed hose can be
shortened depending on your UAV build.
1 Cut the hose to desired length using
atubecutter.
2 Unscrew the knurled locknut on the
inlet tting and feed it onto the tube.
3 Feed the end of the tube onto the
barbed tting.
4 Lock the tube in place by tightening, with
your hand, the knurled lock nut.
Assembly and connection4
Ensure the hydrogen cylinder and FCPM are securely
mounted beforeproceeding.
1 Verify that the connector O-rings are in place and
free from damage or debris.
2 Align the hose connector path with the
regulator pins.
3 Push the hose connector and twist anti-
clockwise. It will click when located.
4.6 SD Card Format
The FCPM takes a micro SD card. This logs health and performance data, aswell as
fault codes. Useful if any fault troubleshooting is required.
The SD card format must be FAT32 and the following folder structure must exist for
the FCPM to log correctly (the system automatically generates this folder):
\\IntelligentEnergy\data
SD card presence must be detected for the FCPM to start up.

Emergency battery usage during ight
If the on-board battery has been used for >1 minute at the end of a ight (i.e. fuel has
been allowed to run low – indicated by ashing RED LED on FCPM) it is advisable to
disconnect the battery from the FCPM (as per above instruction) and ‘balance charge’
the battery on the ground. Use a dedicated battery charger with‘balance’ function
(to maximum of 24V), this ensures all cells within the battery pack are of equal
voltage before ying the UAV.
Start-up conditioning procedure
When you turn on the FCPM into stand-by mode it will automatically enter its own
conditioning cycle. This cycle takes 90 seconds during which a number of valve clicks
will be heard and the fan will stop for a short time. A single short press at any time
will cancel this conditioning cycle and begin powering the UAV. The conditioning
cycle is not compulsory but doing this on days when ying will increase the
eciency of the fuel cell and boost performance.
General maintenance and dormancy
When stored in warm, dry conditions the fuel cell can dry out and power output will
be reduced. In order to regain this performance, the FCPM should be run hard. The
following cycle is recommended:
1 Turn FCPM on - leave for 90 seconds to perform maintenance procedure.
2 Run for 60 seconds at maximum current with no battery blend (>24V).
3 Ramp to the current drawn as quick as possible.
4 Turn the FCPM o.
5 Repeat above cycle as quickly as possible until performance is regained.
Alternatively:
1 Insert the included conditioning dongle.
2 Turn the FCPM on (LED will double ash red, green then amber).
3 Hook output power cable to a constant voltage load unit set to 23.5V, capable of
at least 30A for 650W FCPM or 36A for 800W FCPM.
4 Short press to enable power out (LED will double ash green)
5 FCPM will automatically recondition (this could take up to 20 minutes).
6 LED will ash green once the process is complete.
7 Turn the FCPM o.
Ensure there is sucient hydrogen available to complete the conditioning process.
Recommend storage environment
The hybrid battery should be removed from the unit when stored. Ideal conditions
are 20°C and high humidity. Storing the FCPM in these conditions will increase the
length of time required between dormancy maintenance cycles.

Fault diagnosis should be carried out by trained and competent personnel only.
In addition to the LED state, faults can be diagnosed from the log les on the
included SD card.
The fault codes below are hexadecimal format and will stack.
Alternative product congurations8
The following product conguration are untested by Intelligent Energy
and implemented entirely at your own risk.
Connecting two FCPMs in series
It is possible to connect the output power leads in series to produce equivalent of
12S battery pack, doubling the continuous and peak outputs.
There are some considerations to make before attempting to do this.
1 Power up sequence – since output of each FCPM is enabled with a button
sequence, one FCPM output will be enabled before the other. This means
the output voltage will be 6S (25V) for a period before the other FCPM
output is enabled.
2 Output negative relative to 0V – with two FCPM in series, there will be a
bottom leg FCPM (negative connected to 0V) and a top leg FCPM which will
oat on top of the rst FCPM. If top FCPM is output is enabled before the
bottom, then the output voltage could go negative. To avoid this situation,
appropriately sized diodes should be placed in parallel with the output of
each FCPM as shown above.
3 Interface connections – The top FCPM signals are now referenced to the
bottom FCPM +ve (i.e. referenced to 25V). This means all connections to the
Top FCPM need to be Isolated/Ground level shifted.

Connecting two FCPMs in parallel
It is possible to connect the output power leads in parallel to produce
equivalent of 6S battery pack, doubling the continuous and peak outputs.
There are some considerations to make before attempting to do this.
1 Any dierence in output voltage between each FCPM will mean
the higher of the two will provide a greater share of the output
current. This means hydrogen consumption will be greater for
the FCPM providing the highest share of the power.
2 To avoid Power up issues and back feeding of current from one FCPM
into the other (causing potential damage) it is strongly recommended
to Diode OR the two FCPMs together as shown above.

Using a larger battery
It is possible to replace the existing battery with a larger capacity battery
pack to increase the emergency ight time or increase the peak power
duration of the unit. This 6S battery pack MUST be capable of discharging
at 30A for 650W FCPM or 37A for 800W FCPM continuously in ambient
temperatures without the battery temperature exceeding 60°C/140°F.
Using a smaller battery
It is not recommended to use a smaller capacity battery pack to reduce
emergency ight time or peak power demands unless it is fully understood
that the unit functionality and specication will be compromised. If a smaller
battery pack is used it MUST be capable of discharging at 30A continuously in
ambient temperatures without the battery temperature exceeding 60°C/140°F.
External battery with ideal diode (higher peak power)
In a similar way to connecting two FCPMs in parallel with diodes, it is possible
to connect an FCPM in parallel with an external power source (i.e. 6S battery
pack) to increase peak power. It should be understood that the FCPM will
output ~25V until the fuel cell is unable to provide more power, then the
output voltage drops to the highest power source available (either the FCPM
battery pack or the external battery pack). The external battery pack will not
be charged due to the blocking diodes required for parallel operation.
