In this chapter, we will discuss the DeltaQuad Semi Solid-State Li-ion battery, how to handle it, how to place it inside the DeltaQuad Evo, and how to power up the vehicle.
Auxiliary battery placement
This chapter will discuss how to charge and store the DeltaQuad Semi Solid-State Li-ion battery properly.
The DeltaQuad Evo Li-ion battery is capable of charging within 1 hour at 20 Amperes. Charging at this rate will limit the durability of the battery. It is recommended to charge the battery at no more than 15 Amperes for a maximum lifetime.
Power on the DeltaQuad Dual Charger.
Plug the yellow XT90 connector from the power cables of the battery into the charger.
Take the balance lead which is the smaller group of cables with the white connector and plug it into the respective balance port of the charger.
With the DeltaQuad dual charger, you can charge two batteries simultaneously. Therefore make sure to connect the cables of one battery to the same channel.
Per channel, you have two buttons. One for the current and one for the mode.
Set the mode to "Charge" by pressing the mode button.
We recommend charging the DeltaQuad Evo batteries at 15 amperes. You can cycle through the available values by pressing the current button.
Press start.
Your DeltaQuad Evo battery is now charging.
When not using the battery for a longer period of time it is recommended to storage charge the battery with the provided DeltaQuad Dual Battery Charger. By doing so the battery will be either charged or discharged to 3.7V per cell which equals 50% battery capacity.
Plug in the power and balance cable of the battery to one of the channels of the charger.
Set the mode to "Storage" by using the mode button.
Press "Start".
If the battery is fully charged when using the storage mode, the charger will discharge the battery to 50% of its capacity. This process can take longer as the discharge power per channel is only 40W.
If the battery is below 50% capacity when using the storage mode, the battery will be charged to 50% capacity at the set current value.
The battery should be stored in a safe and dark location between 5 and 30 degrees Celsius. If the battery has been fully discharged, putting at least some charge (+- 50%) before long-term storage is recommended. This can be done by using the storage mode of the dual charger.
This chapter will discuss the proper placement of the main and the auxiliary battery.
The DeltaQuad Evo has a battery bay (blue), a payload bay (green), and an avionics bay (red).
The main battery needs to be placed on the tray in the battery bay which is located at the front of the fuselage.
The tray has the same form and shape as the underside of the battery.
The battery must be placed in such a way that it fits on the tray.
The thicker power cables must exit the bottom of the battery and lead over the top of the battery toward the XT90 socket of the DeltaQuad Evo.
The battery tray will move forward or backward to correct for the center of gravity depending on which payload is installed. Always make sure that no battery cable is located between the battery and the back wall of the battery bay.
The main battery must be always installed in the battery bay as explained above. To extend the flight time and the total mission range of the DeltaQuad Evo, in addition to the main battery, the auxiliary battery can be installed in the payload bay.
Never attempt to fly only with the auxiliary battery as this will lead to an incorrect center of gravity. The main battery must always be installed.
Every DeltaQuad Evo comes with an auxiliary battery payload box.
As with the main battery tray the auxiliary battery holder is shaped like the battery bottom plate.
The auxiliary battery must be placed in such a way that it fits on the tray. The thicker power cables must exit the top of the battery and lead over the top of the battery toward the XT90 socket of the DeltaQuad Evo.
There is a latch mechanism on the auxiliary battery holder which secures the battery in place. After the battery is placed the latch needs to be rotated 90 degrees so it is positioned above the battery.
Always install fully charged batteries! Installing two batteries with different voltage levels can cause a fire.
The auxiliary battery payload box must be installed in payload slot 1, the payload slot at the rear end of the fuselage, as it is the heaviest payload.
Every payload box displays two arrows on top of each handle.
There are corresponding arrows on the left and right sides of the DeltaQuad Evo's payload bay.
The arrows of the payload boxes must match the arrows in the payload bay.
The payload box orientation is important as its I/O board must align with the respective I/O board of the payload slot.
Slide the payload box into the payload slot.
Push both payload box handles down until you hear a click from the payload box locking mechanism to make sure that the box sits properly in its slot.
The frame of a properly installed payload box sits flush with the frame of the payload bay.
Before takeoff, the payload bay must be fully loaded with either two single payload boxes or one double payload box. If not the LCD above the avionics bay will read one of the following messages:
If payload slot 1 is loaded with, e.g. the Nighthawk 2, payload slot 2 needs to be loaded with the empty payload box which comes with every DeltaQuad Evo.
This chapter will discuss how to properly handle the DeltaQuad Semi Solid-State Li-ion battery.
The DeltaQuad Evo is compatible with the DeltaQuad Semi Solid-State Li-ion battery. Using other batteries is not recommended and will impact your warranty.
Use only the DeltaQuad Dual Battery Charger. Do not use a NiCd or NiMH charger - Failure to do so may cause a fire, which may result in personal injury and property damage.
Never charge batteries unattended unless you charge inside a Battery Safe. When charging Li-ion batteries you should always remain in constant observation to monitor the charging process and react to potential problems that may occur.
If at any time you witness a battery starting to balloon or swell up, discontinue the charging process immediately. Disconnect the battery and dispose of it safely. Continuing to charge a battery that has begun to swell will result in fire. Likewise, never use a battery if you find it swollen or ballooned.
Since a delayed chemical reaction can occur, it is best to observe the battery as a safety precaution. Battery observation should occur in a safe area outside of any building or vehicle and away from any combustible material.
Wire lead shorts can cause a fire! If you accidentally short the wires, the battery must be placed in a safe area for observation for approximately 1 hour. Additionally, if a short occurs and contact is made with metal (such as rings on your hand), severe injuries may occur due to the conductibility of electric current.
A battery can still ignite even after 1 hour.
A battery that makes a hissing sound is almost certain to ignite. Consider your own safety and that of your environment before attempting any action
In the event of a crash, after a 15-minute period to ensure the battery was not compromised, you must remove the battery and dispose of it safely.
Only place the battery before the flight, and remove the battery directly after the flight. Always transport the battery in the dedicated compartment of the flight case or in a safe transportation unit such as a fireproof bag or storage container.
In this section we will explain how to power on the vehicle.
The XT90 socket is located on the right side of the battery bay (front view).
The XT90 connector and socket have key features that allow for easy identification and proper alignment during connection. The constricting shapes at the left end of the connector and socket need to align. This design ensures that the connectors can only be plugged in one way.
Insert the XT90 connector of the battery into the XT90 socket of the Evo until fully joined.
Be sure to push the connector in fully to ensure a secure connection. If the connectors are not fully joined, the vehicle will still be able to switch on but the connectors could overheat. During the flight, due to vibration, the battery plugs could even come loose resulting in the vehicle losing power.
When powering up the DeltaQuad Evo, it will go through an initialization routine that can be monitored on the Evo's LCD display located above the avionics bay:
After the successful initialization, the LCD will read "Ready to fly".
If the initialization can't be completed due to an error, the LCD will give information indicating how to resolve it.
The following is a complete list of messages and their explanations.
Every payload box carries information about its weight and weight distribution. This information is stored on the I/O board of the payload box.
Depending on the installed payloads the DeltaQuad Evo will automatically balance itself by moving the main battery tray to the front or to the back.
The DeltaQuad Evo can compensate to a greater extent for tail heaviness rather than nose heaviness. That is why the main battery tray can move more forward than backward. This is the reason why the heavier payload must be always installed in payload slot one, the most aft payload slot close to the pusher motor.
After placing the main battery as described in the chapter the XT90 connector of the battery needs to be connected to the XT90 socket in the battery bay.
