Remove Battery from Tello Drone: Safe Step-by-Step Guide
A practical, beginner-friendly guide to safely removing the Tello drone battery with step-by-step instructions, safety tips, and storage best practices.
Learn how to remove the battery from a Tello drone safely and correctly. This quick guide highlights power-down steps, locating and releasing the battery latch, and lifting the pack without stressing the wiring or shell. You’ll also see post-removal checks to protect your drone, battery health, and future flight readiness.
Understanding the Tello battery design
Understanding the Tello battery design helps you remove it safely and without damaging the drone. The Tello uses a compact LiPo cell that slides into a rear compartment and is secured by a small latch. In this guide on how to remove battery from tello drone, you’ll learn why powering down completely, locating the latch, and lifting the battery straight out matters for both safety and battery health. By treating the battery and contacts with care, you reduce the risk of puncture, short-circuit, or pinched wires during removal. This overview of the hardware layout prepares you for the step-by-step process and helps you approach the task with confidence and calm.
Safety basics before you start
Before touching the drone, ensure you’re in a clean, dry environment and that the aircraft is not powered. Remove any charging cables and place the drone on a stable surface. Keep your hands dry and avoid touching the battery terminals with bare skin. LiPo batteries can ignite if damaged or shorted, so never attempt removal if you notice swelling, damage, or exposed metal. By establishing a safe workspace, you’ll minimize risk and create a controlled environment for the battery removal procedure. This section emphasizes safety as the foundation for successful maintenance.
Tools and prep
Gather a few simple tools and a safe storage setup. A flat, non-slip work surface is essential to prevent the drone from slipping during removal. Have a small LiPo-safe storage bag or metal container ready for the battery after removal, and a clean, lint-free cloth to wipe down contacts. Optional tools include a non-marring pry tool if the latch proves stiff. Finally, confirm you have personal protective gear, like safety glasses, in case of any unexpected battery venting, though this is rare with proper technique.
Where to find the release mechanism
On most TellO models, the battery sits toward the rear underside of the body. Look for a small latch or tab that locks the battery in place. The release is typically a short slide or press action; you may need to press and slide the latch toward the center of the drone to unlock the battery. If the latch feels sticky, avoid forcing it and check that you’re lifting from the correct area. Proper identification of the release mechanism prevents accidental pinching or damage to the battery housing.
Handling and latch operation (visual cues)
When you’re ready to remove the battery, orient the drone so you can access the latch with your fingers. Use a gentle, steady motion to disengage the lock: press or slide the latch fully, then tilt the battery away from the shell to create a safe clearance. Keep your grip secure and avoid applying heavy pressure on the battery terminals. Visual cues, such as the latch moving freely and a clear gap between the battery and the drone, indicate a successful release.
Inspect the battery and compartment after removal
With the battery out, inspect both the battery and the compartment for any signs of damage. Look for swelling, cracks, or loose connectors. Wipe the battery contacts with a dry cloth if needed, and avoid using liquid cleaners. Place the battery in a LiPo-safe bag or fireproof container if you’re not immediately re-installing or charging it. If you notice any swelling or unusual odor, do not reuse the battery and consult the manufacturer’s guidelines.
Storage and safety after removal
Store the battery in a cool, dry place away from heat sources, metal objects, and direct sunlight. A LiPo battery should be stored at a partial charge (typically around 3.8-3.9V per cell) in a fireproof container or LiPo bag. Do not leave the battery loose in a bag with keys or coins that could pierce the casing. When you’re ready to fly again, reinsert the battery following the manufacturer’s reinstallation steps and perform a quick preflight check.
Common mistakes and how to avoid them
Common mistakes include forcing the latch, touching the battery terminals with bare skin, or removing the battery when the drone is in an unstable position. Avoid rushing the process, and always place the drone on a flat surface. If you feel resistance, stop and re-check alignment and orientation. Proper technique reduces the risk of pinched wires and damaged contacts.
Quick reference: post-removal checklist
After removing the battery, double-check that the drone is powered off, the area is clear of cables, and the battery is stored safely. Confirm the battery’s condition and note any changes in performance if you plan to reuse it soon. This quick check helps ensure you’re ready for your next flight and that safety standards remain high.
Aftercare: what to do next
If you will re-install the battery later, connect the battery only when the drone is completely dry and on a stable surface. Inspect the airframe for any signs of dust or debris that could interfere with the seal. For frequent users, consider scheduling regular maintenance checks to maintain battery health and drone longevity.
Summary for beginners
For new pilots, removing a Tello battery can feel daunting at first. With a calm approach, clear workspace, and careful attention to the latch release, you’ll gain confidence quickly. Practice on a powered-down unit first, then advance to routine maintenance without the stress that comes from hurried handling.
Tools & Materials
- Flat, non-slip work surface(Clear area to place drone)
- Power-off the drone(Hold power button until lights go out)
- Non-marring pry tool (optional)(Use if latch resists release)
- Clean cloth(Wipe any fingerprints from contacts)
- LiPo-safe storage bag or fireproof container(Used for storing the removed battery safely)
Steps
Estimated time: 5-8 minutes
- 1
Power down the drone and unplug from charger
Ensure the TellO drone is fully powered down and not connected to any charger. This prevents any short or unintended power flow during battery removal.
Tip: Keep hands dry and avoid gripping on the propeller hubs. - 2
Locate the battery bay and release latch
Turn the drone so you can see the back/bottom edge where the battery sits. Find the small release latch or tab that secures the battery in place.
Tip: Use a gentle, straight push rather than twisting the latch. - 3
Release the battery by sliding or pressing the latch
Apply the required motion to unlock the battery. Depending on model revision, you may press and slide or simply pull the latch away from the battery.
Tip: If resistance is felt, stop and inspect for a misalignment. - 4
Lift the battery straight out
Grasp the battery with a stable grip and pull it straight toward you, keeping it level to avoid bending contact pins.
Tip: Avoid touching the battery terminals with bare skin. - 5
Inspect the battery and compartment for damage
Before storing or reusing, visually inspect for swelling, corrosion, or loose connectors. Do not reuse if damage is found.
Tip: Place the battery on a non-conductive surface when inspecting. - 6
Safe storage or proper disposal
Store in a LiPo-safe bag or fireproof container, away from heat or metal objects. If damaged, follow local disposal guidelines.
Tip: Do not store near flammable materials.
