Pulse Defender Usage, Warnings & Info:
The Pulse Defender was designed as a safety back up device to offer continuous power to the receiver or flight controller when an electrical power loss takes place. The Defender does not offer power to the motor - it is a redundant back up device, allowing the option of a powered off glide or auto rotation in the event of full electrical power loss.
Do NOT use the Defender as a main power supply for your servos or electronics, as the Defender is designed as a backup defense only, and cannot be used as a main power supply.
Before Your Flight:
Be sure the Defender has been fully charged before usage. After being charged, power up all electronics and test electronics before the Defender has been activated, thus making sure all systems are operating normally. Plug in the Defender to your receiver or flight controller and press the black power button to power the Defender, which will allow the Defender to protect your aircraft in the event of a full electrical power loss while in flight.
After Your Flight:
Once your flight has ended, unplug the Defender from your receiver or flight controller to protect the battery from being discharged while not in use. If the Defender is left plugged in for a prolonged period of time without receiver / BEC power, the battery will be irreversibly drained in power, which will result in permanent and terminal battery damage.
Do not leave the Defender plugged into the receiver or flight controller after the flight has ended. Leaving the Defender plugged into the receiver or flight controller for prolonged periods of time (without main flight pack power) will deeply discharge the battery and damage the Defender battery, which will not be covered under warranty.Defender Specifications:
Battery: Pulse 500mAh 2S 7.4V / 2C Charge Rate
Weight: 38g (Including Connectors)
Size: 55mm x 31mm x 18mm (LxWxH)
The Pulse Defender is not a substitute for sustained receiver power. To save weight and reduce the overall footprint, the 500mAh 2S 7.4V LiPo battery does not have the capacity for long duration power supply, so be sure that the Defender is only used for it's main design purpose - a battery back up system in the event of a BEC or receiver power failure.
The Pulse Defender Consists of the Below:
(1) Pulse Defender Main Board
(1) Pulse 2S 7.4V 500mAh LiPo Battery
(1) Auxiliary LED Light
Defender Usage & Functionality:
The Defender is designed for easy use & functionality, making use & application of the Defender within your aircraft a seamless & simple process. Please carefully review the below information to make sure the Defender is properly utilized to provide the maximum levels of safety with the aircraft of application.
Before 1st Use:
The Pulse Defender ships with a storage charge of 3.7V - 3.85V per cell and will require charging before use. Charging can take place via a dedicated LiPo battery charger, allowing the 2S 7.4V LiPo battery to be fully charged for use. This will be the only time the battery needs to be charged via normal day to day use, as the Defender will charge its battery by drawing from the BEC power or receiver pack power.
- Secure the Defender in your aircraft in a location that allows easy access of the Power Button on the main board, as the Defender will need to be powered on before the flight and powered off once the flight is finished.
- Allow access for the LiPo balance lead to be plugged into and unplugged from the main board. The Defender draws a small amount of power, and if the battery is left plugged in without BEC / receiver pack power, the LiPo battery will be drained and damaged.
- If using the auxiliary / optional LED light, locate this in an area that is visible from outside the aircraft. This is especially important with receiver battery powered aircraft, as any receiver battery power failure will shift the power load to the Defender, and the LED light will flash rapidly, alerting the pilot of the power failure. If this is not visibly seen, the pilot may continue flying the aircraft using the Defender power source, which is not designed for sustained power.
Connecting the Defender:
-Connect the Defender to your receiver or flight controller via the power wire - any available servo / battery port via the receiver or flybarless unit can be used. If a port is not available, a Y-Harness can be utilized.
-Connect the Defender LiPo battery to the Defender board via the white balance plug.
Powering the Defender On & Off:
- Before powering on the Defender, power on the BEC or receiver pack and verify all electronics function correctly, such as servos & flight controller. Once verified, power on the Defender by pressing the small, black power button located on the Defender board.
- When the Defender is powered on and functioning properly, the LED light via the board (and auxiliary LED light, if used) will slowly flash every (4) seconds, indicating the Defender is ready to provide power if a BEC / receiver battery failure takes place.
- If you would like to test the Defender, make sure the Defender is powered on, and simply remove BEC or receiver power to verify the Defender is properly functioning. Servos, receiver & flight controller should remain functioning when BEC or receiver power is removed.
- When the flight has ended, power off the Defender by pressing the small, black power button located on the Defender board.
- If flights have ended for the day, unplug the white LiPo battery balance plug from the Defender board to prevent the Pulse Defender battery from being depleted and damaged.
LED Light Status Info:
- Slow Red LED Flash: The Defender is working normally and is in "Defender Mode," awaiting a voltage drop or complete voltage loss.
- Steady Red LED Flash: The Defender battery is charging by pulling power from the BEC or receiver pack.
- Ultra Rapid Red LED Flash: The Defender has sensed a voltage drop or voltage loss and is now powering the aircraft electronics.
Defender Battery Voltage:
- The Pulse Defender utilizes "Smart Sense" technology to read and replicate the input voltage of the BEC or receiver pack voltage. In the event of a failure, the Defender will apply the correct voltage the system requires based upon the initial voltage readings.
- If any BEC voltage adjustments are made for any reason, the Defender does not need to be reset, as the Defender will always read the BEC or receiver pack voltage before any power is applied, thus protecting the electronics from any excessive voltage the Defender can deliver.
- If the Defender will not be in use for more than (2) weeks, we recommend placing the Defender into a storage charge mode of 3.7V - 3.85V per cell, as storing any LiPo battery at full charge for greater than (2) weeks can subsequently damage the battery, and is not safe.
- If the Defender is placed into a storage charge mode and later used again, be sure the Defender is fully charged via a LiPo battery charger before 1st use of the Defender.
The Pulse Defender battery is covered by a (3) month manufacturer warranty, with the Defender board being covered by a (1) year warranty. This warranty is based upon the noted time from date of purchase and is not based upon how many times the unit has been utilized.
Warranty will be voided regarding the below actions:
- Crash damage
- Improper charging
- Battery being stored at full voltage with no storage charge
- Battery being depleted by being left plugged into board while not in use
- Only utilize a dedicated LiPo battery charger to charge the Pulse Defender, as improper charging can lead to battery damage and or fire.
- Due to fire risks of LiPo batteries, we do not recommend the Defender to be stored in the aircraft while not in use.
- Due to the fire risks of LiPo batteries, store the Defender in a safe location free of any combustible materials. We recommend a LiPo bag or LiPo safe.
- Do not store or charge the Defender inside a home, garage, vehicle or any area with combustible materials.
- Be sure to disconnect the Defender battery from the Defender board after aircraft usage has ended for the day. If the Defender battery is left plugged into the board, the battery will be depleted and damaged.
- If the Defender is not used for more than (2) weeks time, place Defender into a storage charge mode - 3.7V - 3.85V per cell. Storing the Defender at full charge will damage the battery and poses a risk for fire.

Pulse Defender vs. Other Guard
The Pulse Defender offers the below capabilities & functionalities, offering superior performance when compared to the OptiGuard back up system:
- Reads continuous voltage every millisecond for faster reaction when power is lost
- Utilizes an analog chip set instead of an MCU unit, allowing faster overall read & response
- Supports weak BEC if a weak BEC is recognized in flight, providing power for transient power loss if a BEC issue is at play
Why Power On / Off vs. Auto?
The Defender uses a manual "On / Off" feature versus an "Auto On" system, as we felt this option gave the end user the best overall functionality and protection, such as:
- Allows the user to optionally power on / off unit at will based upon need or demand
- Prevents battery drain / damage by allowing unit to be shut down, versus "auto on" that can't be shut down
- Protects electronics in the case of voltage back feed, as an "auto on" system would power system and potentially damage electronics / mechanics

This unit is lightweight and gives a peace of mind in case of a BEC failure. You do have to power it on unlike the other backup device I have but I can see how this is good and bad. Hopefully I won't actually need this in flight.
Like this little backup, lightweight, small, only wish it was in a housing for easier mounting but not a big deal...
Excellent little unit at a good price. Works as advertised, red LED is visible during flight . Just remember to unplug the battery if not using for days at a time.
Ideal for hooking up to your RC Heli to test servos and or power up your vbar For programming purposes
installed the unit on my Align 700 , works great , need to get one for my 800 .
I received the Pulse Ultra Defender and it is a small unit (Perfect for 500 size and up). I tested it on the bench prior to install it. I use a 2s battery to power the electronics on my Goblin Urukay. When I unplugged the battery, the defender detected it instantly and the LED started flashing. You just have to power it after you power the electronics. I am building a gas powered heli and I will use one in it too as flight time will increase :-)
