How do you use the lithium battery correctly?

Some people thought that the better the lithium battery brand, the higher the price is. Even it is better to use longer. But it is not the case, even if it is a good lithium battery will be occurred, described below lithium electricity cause of over discharge:

Model aircraft lithium batteries used method is the most critical. Now the author use know card 130 yuan 1800 mah12c, very satisfied. Electrical modulation is based on the percentage of the size of the battery voltage to automatically remind to protect the battery power. Set up 65%, for example, a 11.1 v battery to 11.1 x65 % = 7.2 v electric power will be warned. But you don't forget, this is calculated in the case of the full power of 100%. If she shut a receiver (such as debugging), then the bad luck comes, midway shutdown, assuming that the remaining 10 v voltage, then, to open, the protection of the electrically controlled voltage went down to 10 x65 % = 6.5 v. The lower the more sad...The situation is very serious, is the battery discharge. Although the battery voltage fall ill from power can also judge, or have already can't fly, but still very dangerous, but they will have a place. Therefore, from the start to the end of the flight, the battery can't power outages, otherwise should be full of flying again. The electricity while atos has mentioned in the specification. As for the charged debugging, you can set the throttle hold to ensure safety.

How to use the right of this lithium battery?

Please note that whether Li-ion battery 3.7 V or 1.2 V Ni-Mh, does not mean that the battery fully charged when the voltage.For lithium electricity, after full voltage of 4.2 V, believe that most people have the universal charger mobile phone battery, you can see, usually with each output voltage is 4.2 V.The nickel metal hydride is full of electricity can reach about 1.5 V.In addition to the voltage, and then there is capacity and discharge rate.The capacity of the battery in mah (mAh), for the unit with the C discharge rate.In C, simple said.1 c for different capacity of the battery is not the same.1 c is refers to the battery 1 c discharge can continue to work for 1 hour.Example: 1500 mAh capacity of the battery last for 1 hour, then the average current is 1500 ma, namely, 1.5 A, 1.5 A is the battery 1 c. If the above nominal 10 c. yao put the battery's biggest current is 1.5 A * 10 = 15 A.That said the battery under 15 a use is safe.Such as 1000 mah capacity in 1 c is 1000 ma, which is 1 a..If the above nominal 15 c. So the biggest current is 1 a * 15 = 15 a, the battery current is 15 biggest a. however, above the battery work in 15 years, is 10 c discharge, maximum current work in theory use 60/10 = 6 minutes.And 1000 mAh work in 15 years, it is 15 c discharge, theory in the current work can use 60/15 = 4 minutes.So, in contrast, 1500 mAh, 10 c batteries to be used for a long time point.So buy battery light see C number is no good.C for small discharge the battery may be larger than C for discharge.The associated with capacity.

Remote control model aircraft called the lithium battery lithium polymer battery, generally referred to as lithium electricity or lithium batteries.Based on the 11.1 V remote control model aircraft lithium battery for example how to correctly use lithium electricity.Usually, 11.1 V remote control model aircraft lithium battery is composed of three slices of lithium batteries in series (3 s1p), namely every piece of batteries voltage of 3.7 V.Model, mobile phones, cameras and other lithium voltage marked on electric voltage as labels, from an average working voltage.Monolithic lithium batteries the actual voltage is 2.75 ~ 4.2 V, marked on the lithium electricity discharge capacitance is 4.2 V to 4.2 V power.Remote control model aircraft lithium batteries must be kept in use in this voltage range from 2.75 V to 4.2 V.Such as remote control model aircraft lithium battery voltage is lower than 2.75 V belong to excessive discharge, lithium electricity swells, internal chemical liquid crystal, the crystal may be pierced internal structure layer caused by short circuit, may even make Li-ion battery voltage to zero.Remote control model aircraft belonging to overcharge lithium battery voltage is higher than 4.2 V, the internal chemical reaction is too fierce, lithium electricity will swell, cheerily if continue charging swells, burning.Both discharge and charge all can produce a lot of damage to the remote control model aircraft lithium battery.

1, the charging

1-1 charging current, charging current shall not exceed the maximum charging current specified in the specifications (typically 0.5 ~ 1.0 C or less), using the above recommended charging electric current would be likely to cause the battery charge and discharge performance, mechanical performance and safety performance problems, and could lead to a fever or leakage.Current market sales of 5 c model aircraft battery charging current and suggested that do not often use 5 c charging, lest affect battery life.

1-2 charging voltage, charging voltage shall not exceed the prescribed limits voltage (4.2 V/monomer battery), 4.25 V charging voltage of the highest limit for each section.(it is forbidden to use the batteries, otherwise may cause rechargeable batteries, user consequences due to wrong battery).

1-3 charging temperature: the battery must be in the product specifications stipulated by the environmental temperature range, otherwise the battery is susceptible to damage.When your battery surface temperature anomalies (refers to the cell surface temperature more than 50 ° C), should immediately stop charging.

Reverse charge 1-4: correct connection is the cathode of the battery, it is strictly prohibited to reverse charge.If it is negative to the, will not be able to charge batteries.Will reverse charging the battery is damaged, or even cause fever, leakage, burst into flames.

2, discharge

2-1 discharge current, discharge current shall not exceed the specifications (admit) maximum discharge current, large current capacity discharge can lead to collapse and lead to a battery overheat.

2-2 discharge temperature: battery must be within the specification of working temperature range.When the battery surface temperature over 70 ° C, to temporarily stop using, until the battery cooling to room temperature.

2-3 over discharge, over discharge can cause cell damage, discharge shall not make monomer battery voltage is lower than 3.6 V.

3, storage

Battery should be stored in a cool environment, long-term storage battery (more than 3 months), recommended temperature is 10 to 25 ° C and low temperature no corrosive gas environment.Battery charge and discharge every 3 months in the process of long-term storage of activity to keep the battery at a time, and to ensure that each cell voltage in the range of 3.7 ~ 3.9 V.
