Takeaway: unmanned aerial vehicle (uav) developing rapidly today, all walks of life use quite a lot. So for unmanned aerial vehicle (uav) energy storage parts, batteries, is how to maintain? Let‘s introduce uav‘s most popular form of lithium batteries in the battery, how to maintain, how to prolong its service life.

A, but

Some of this there are requirements for the charger, the charger after full power of the function is not perfect, lead to single battery is 4.2 V is not stop charging, in addition, some charger use after a period of time, because components ageing, also prone to stop problem, therefore, when the lithium polymer battery must be someone to look after, when found the charging time is too long, to check whether the charger failure, if failure to remove the battery as soon as possible, otherwise the lithium polymer battery overcharge, then affects the battery life, light weight, appear directly burst into flames.

In addition to remind everybody, must according to the regulations of the battery when charging charge number C or lower C, shall not exceed the prescribed charging current.

Second, but put

Battery discharge curve indicates that just began to discharge, the voltage drop is faster, but the discharge between 3.9 ~ 3.7 V, the voltage drop. But once fell to 3.7 V, the voltage drop speed will be faster, bad control leads to discharge, light damage to the battery, or voltage is too low to cause drone bombing. Some friends die because the battery is less, so every time they fly, the battery was short-lived. Strategy is, as far as possible to fly a minute, life is much fly a cycle. It is better to buy two pieces of batteries, the battery every time fly to exceed capacity limit. To make full use of the battery alarm, a alarm should be down as soon as possible.

Three, dissatisfaction with electricity save

Fully charged battery, can not be full electricity save more than 3 days, if you don‘t put off for more than a week, some cells directly bulge, some cells may temporarily don‘t drum, but several times after full electricity saving, the battery may be scrapped directly. The right way is, therefore, recharging after received the mission, such as in 3 days after the battery no mission, monolithic voltage to charge, please to preserved from 3.80 V to 3.90 V. Again after good electrical charge for various reasons did not fly, also want to be in full within 3 days after discharge of the battery to 3.80 ~ 3.90 V. If don‘t use the battery in three months, will continue to save the battery charge and discharge time, which can extend battery life. Batteries should be stored in a cool environment, long-term storage battery, best can in sealed bags or sealed box, suggest the environment temperature is 10 ~ 25 ° C, and dry, no corrosive gas.

Four, no damage to the skin

The husk of the battery is to prevent the battery explosion and leakage of the important structure of the fire, the aluminium skin of lithium polymer battery will directly lead to damaged battery fire or explosion. The battery to should take put down gently, fixed the battery on the plane, cable tie to tighten. Because there will be doing a large dynamic flight or fall off, the battery will be thrown out because of the cable tie is not tight, so it is easy to cause the battery damaged skin.
