It is essential to pay extra attention to battery management in order to extend battery life, maintain performance and improve safety.
At Flyability, we have engineered a whole new charging device that allows to not only charge the batteries but also to put your batteries to storage or transport capacity.
You can learn more about batteries in general in our article Battery Management and complementary information.
BATTERY MANAGEMENT AT FLYABILITY
Safety is a major concern when we speak about batteries. At Flyability’s office, we are taking all the necessary precaution to charge and store our batteries safely. To do so, we have put in place a Charging station as follow:
A metallic cupboard is hosting the following items:
- Charger & charging box
- Metallic boxes to store the batteries. Each pilot has its own labeled box as he is accountable for his own batteries.
- Personal boxes for each pilot to store their Personal Protective Equipment (PPE)
Charger & charging box
We are using the Elios charger discharger (available in our online shop here) to take care of our battery. To increase safety, we place the battery while charging in a Battery charging box such as the Bat-Safe (available at http://www.bat-safe.com/) mitigating all fire hazards.
As we often go on missions with 10 batteries, we like to save time handling the batteries by being able to easily and quickly fully charge or discharge all of them in one session. For this reason, we have 5 Elios charger discharger in our charging station.
Battery storage box
When a battery is not used for more than 3 days, it is important to have them at Storage capacity. It is also important to keep them safely stored at all time. At the office, we use a metallic box, on the field we use LiPo safe bags.
Each pilot is accountable for his own batteries. Hence, we use labeled metallic boxes. On the image below, we a 0.30 CAL 19A1 cans. 2 safety LiPo bags with 5 batteries in each perfectly fit in one. Be careful, if you wish to do the same, you should punch a hole in the joint to hole pressure to vent in the event of a battery catching fire.
Each pilot has his own protective equipment. The box contains:
- Safety shoes
- Hard hat
- Eye protection
- Ear protection
HOW WE CHARGE BATTERIES FOR MISSIONS
As it is paramount to keep the batteries at storage capacity, we try to keep them at this state as much as possible.
We are describing below how the general process for battery handling.
- If it is necessary to take the plane, puts the batteries at Transport capacity to comply with the IATA regulation.
- Only charge the batteries at 100% up to 3 days before a mission
- On-site, charge the batteries in LiPo safety bags
- After a flight, let the batteries cool down at least 30min before charging them again
- Never connect the charger if the power cable has been pinched or shorted.
- Never connect the charger to an automobile 12V battery while the vehicle is running.
- Never attempt to dismantle the charger or use a damaged charger.
- Never cover the cooling slots.
- Never use the charger with another battery than the LiPo battery provided by Flyability
