With the growing season winding down in the northern hemisphere, some growers might be thinking about putting their drones away for winter storage. Drones use lithium polymer (LiPo) batteries which are very powerful and lightweight compared to most other types of batteries, but LiPo batteries also need special care for storage. Follow these tips to get the best performance and life out of your drone’s batteries.
Fortunately, the Agrion’s batteries are just as easy to use as the Agrion itself. Each battery has a small computer circuit built in that monitors the health and condition of the battery.
LiPo batteries can be damaged if they are stored fully-charged for long periods of time. To avoid this, the Agrion batteries’ internal circuit will slowly discharge itself after a period of time to prevent damage. However, drone operators should be careful not to put an Agrion battery into storage if it is very low on charge. It is recommended to charge the Agrion batteries to two-bar’s worth of charge before storing. Agrion batteries should be stored in a temperature controlled (i.e. between 50 an 80 degrees f), dry place for the winter.
Enduro and Hornet Batteries
The LiPo batteries used in the Enduro quadcopter and Hornet fixed-wing drones do not have a self-discharge feature. If a LiPo is left fully-charged for a period longer than 7-10 days, it will start to become internally damaged and cause damage to the battery. The longer it is left, the more damage will occur, resulting in decreased performance and life.
In order to prevent damage, simply prepare the LiPo batteries using the included battery charger. Set the charge mode on the charger to Storage, plug in the battery’s cables as normal, and start.
The Storage charge function will reduce the battery’s voltage to approximately 40-50% of total charge which is the optimum voltage to store LiPo batteries. LiPo batteries should be stored in a temperature controlled, dry place for the winter.
