Introduction: How to Extend the Lifetime of You TATTU Professional UAV Lipo Battery

As a kind of “accessory” for drones, TATTU professional UAV lipo battery is one most “expensive” . Not because its high retail price, but because it can easily get damaged for careless handling.

How to achieve better use of a lipo battery? There are three aspect you need to take care of three parts.

Step 1: 1.Charging

Use only a charger approved for lithium batteries.

Lithium polymer chargers use a different charging algorithm than any other type of battery charger. For this reason, a lithium polymer charger must be used when charging your LiPo battery pack.

Charging current

The current should never exceed a 1C charge rate during LiPo battery charging.

Never charge the batteries unattended.

Use a safe surface to charge, better in a open ventilated area, and keep a bucket of sand nearby in case of catching fire.

Do not charge several packs at the same time

Step 2: 2.Discharging

Discharging during the use of lipo battery. New cells may have a high initial charge, and care must always be taken to insure that the battery is not short-circuited.

Discharge current Discharge current shall not exceed the maximum discharge current on specifications, large current discharge can cause capacity dropped sharply and lead to a battery overheat

Discharge temperature Do not use the battery where ambient temperature may exceed 140F/60C. Stop using when surface temperature of battery exceed 70C.

Do not over discharge Voltage of single cell should not be lower than 3.6V. Over discharge will damage the battery.

Step 3: 3.Storage & Transport

Storage temperature

Suggested low temperature 10℃-25℃ for storage, and no in corrosive gas environment. Put lipos in plastic zip top storage bags and place them in the fridge when not in use. When you take them out leave them in the bags, to prevent any atmospheric moisture from condensing on them as they warm.

Storage voltage

Ensure that each cell voltage in the range of 3.7 ~ 3.9 V, and charge and discharge every three months in order to keep activity of cells.

Step 4: 4.Transport

Prevent severe vibration and shock in transportation. Handling the battery gently, and use soft packaging protection.
