Knowing the lithium battery safety knowledge can save your life at a critical time

Jonathan Strobel, a resident of Palm Beach County, Florida, alleges in the suit that his Note7 was in his right pocket on Sept. 9 when it exploded, causing "severe burns" to his leg, leaving him "in shock and extreme pain due to his injuries". Nearly a million Note7 smartphones were sold in the United States. The recall applies only to Samsung Galaxy Note7 phones sold before Sept. 15, 2016. Samsung has received 92 reports of the batteries overheating in the U.S, including 26 reports of burns and 55 reports of property damage, including fires in cars and a garage. Three Australian airlines have banned passengers from using or charging Samsung Electronics' Galaxy Note 7 smartphones during flights due to concerns over the phone's fire-prone batteries.

Samsung Note7 mobile phone batteries like most cell phone batteries are lithium batteries, lithium batteries are more and more widely used in our daily-life, such as our unmanned aerial vehicle batteries are lithium batteries, so learning how to use and maintenance the unmanned lithium batteries is very important.

Why did the lithium battery explosion?

Lithium battery are better than lead-acid batteries, nickel-cadmium batteries, nickel hydride batteries in performance, and it is better than fuel cells in discharge times. But the safety of lithium batteries still needs to be improved. The biggest hazard of lithium batteries are lithium cobalt oxide lithium batteries in case of overcharge lithium anode formed in Dendrite and pierces the diaphragm, forming internal short circuit. External short circuits, internal short circuit will yield hundreds of amperes of current, resulting in a battery explosion is overheated.

How to use lithium batteries?

1.The charge voltage should not exceed specified limited voltage (each battery chip is 4.2 volts), 4.25 volts is the highest limitation of each charge voltage. Charge current should not be too large (like the TATTU brand charger of 1500mAh 3s battery should be set at 1.5 amperes to 2.5 amperes to charge)

2.Connect battery positive and negative electrodes correctly. If the anode and cathode of battery swap the cell's poles over will not accept a charge. Reverse charge will make battery damage, cause heating, explosion, leaking and burn.

3.Over discharge will make battery damage. When the battery discharges, monomer battery voltage should not be less than 3.6 volts (When single cell is 3.8 volts, the plane should almost begin to descend.)

4.The battery should be kept in a cool environment. When storing the battery for a long time (over 3 weeks), suggested to put in the environment that temperature keeps at 10 to 25 degree Celsius, low temperature and non-corrosive gas. Battery needs to charge and discharge once three months to keep battery activity, and ensure every chip voltage in the range of 3.7 to 3.9 volts.

5.A good battery should have a good charger. Don't use no-name charger.

6.FPV must choose the branded batteries, don't use unknow batteries. Single cell voltage has big difference.

Tattu drone battery

The safety of lithium batteries is not a peripheral issue, it is based on the material nature of technology issues. Battery factory safety testing must also be stricter. The source of Samsung Note 7 battery issue hould be battery manufacturing issues. For most drone lovers, how to Choose a drone battery?
