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 defence only, and cannot be used as a main power supply.
Before Your Flight:
Be sure the battery utilized with 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.

Pulse Defender Usage Instructions & warnings - Please Read Carefully!
The Pulse Defender is designed as a battery backup for in flight power loss, allowing for an auto rotation or dead stick landing when BEC / receiver power is lost. Designed to be paired with a 2S 7.4LiPo battery (JST-XH balance tab), the Defender will power your receiver, servos and flight controller (if applicable) when BEC / receiver power is lost.
The Pulse Defender is not a substitute for sustained receiver power, 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 Board Consists of the Below:
(1) Pulse Defender Main Board (LiPo Battery NOT Included)
(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:
- Utilize a 2S 7.4 LiPo battery of your choice - JST-XH balance tab. 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 2S 7.4V LiPo battery to the Defender board via the white JST-XH 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 utilises "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 2S LiPo battery of your choice 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 battery (sold separately) 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.
