UAV FOR DEFENCE

Time is essential during a military operation; the outcome can change within seconds, meaning the difference between life and death. In that respect, the defence drone is the perfect choice due to its abilities within scouting and reconnaissance.

UAV FOR NON-GOVERNMENTAL

Severe damage to infrastructures and high casualties caused by natural disasters call upon help from drone scouting and recon. Providing valuable information from areas which often are unmanageable, UAV can be a vital part of saving lives.


Extra function

If you need such following wireless function for the battery, you can add this Bluetooth function

1. Select our Smart battery PCM which transmits the battery data through bluetooth module then displays it through mobile APP.you will easy to check the battery status in any time,which will be quite helpful to mange the battery in the future.

2. There are two types of Bluetooth module: one is integrated type in the PCM; the other is external type with connector.

3. The Bluetooth module supports many communication protocols of CANBus,SMBus,HDQ,I2C,RS232,RS485. It’s also compatible with different brands of control IC: TI,O2Micro,Maxim,Freescale and so on.

Lithium Battery Safety

Using Lithium Batteries Safely is Extremely Important as they can easily catch fire or even explode.

Lithium batteries need special handling because physical damage or short circuiting them is likely to cause them to catch fire.

Store them in a special bag (above right) when not in use or while charging and keep the bag where it could contain a fire.

If a LiPo pack starts to expand (puff up) or if it won't take a full charge on all cells, dispose of it.

Before disposal a LiPo battery should be discharged by connecting it to a resistive load (light bulb or charger-discharge function).

It is a good idea to keep a metal bucket filled with sand handy in case a LiPo fire needs to be quenched.

DO NOT put water on a burning LiPo Battery, lithium takes oxygen directly out of water and keeps on burning.

Lithium batteries are especially likely to misbehave while charging or discharging or when dropped.

Although Lithium Ion batteries have more energy, 18650 batteries are safer due to internal overload protection and steel case.

 

 

 

Lithium Ion batteries can have one major advantage, up to twice the energy density of a LiPo.

They are always cylindrical and generally have a metal casing giving up some space and weight, but not much.

Even with those constraints Lithium Ion batteries normally have at least 70 percent more energy density by weight than LiPos.

This directly translates to 70 percent longer flight time (if you can use them).

The Achilles heel of the Lithium battery for our use is it's low discharge rate.

Current Lithium Ion batteries have a 2C Discharge rate and if you drain them above that rate it will damage the battery.

In fact many of the popular Lithium Ion batteries now include built in protection against charging or discharging too fast.

But for our use this only means that if you need more power than the battery is rated for it simply won't provide it.

If you are flying a multicopter and a motor needs to speed up for stability and the power is not available you have a problem.

Or if your airplane needs more power than is available, it can pull down the electronics and servos to where they won't function.

Nonetheless, the high energy density definitely justifies designing UAVs that can work within the Li Ion discharge envelope.

A properly designed copter could get 40 to 60 minute flight times and an airplane up to two hours with lithium ion batteries.

A secondary advantage of lithium ion batteries is that they can operate to over a thousand charge cycles if properly cared for.

The NCR-18650 Lithium Ion Battery pioneered by Panasonic is available in a variety of single cell energy capacities.

Since lithium ion batteries come as single cells you will need to either "spot weld" several together with tabs or use a holder.

It is recently becoming possible to buy stock and custom battery packs of 18650 type lithium ion batteries.
