LithiumPolymer (LiPo) Basics

 

It cansometimes be difficult to know which battery is best for your application.

There is ahuge variety of batteries available and while many may suit your applicationyour ultimate goal is to purchase a battery pack that will;

-be withinyour budget

-have a longcycle life

-have thecorrect size and weight

-give youthe longest flight times

-be able todeliver the correct voltage/amp (Power)

We hope thissimple guide helps you understand the different types of LiPoly (LithiumPolymer) batteries and which is right for your model.

 

You may havenoticed by now that batteries have different ratings, sizes, plugs, wire,charge rates and chemical makeup. Lets decipher;

 

Capacity(mAh).

This isusually the biggest number shown on the pack and is measured in mAh(Milliamp/hour) or Ah (Amp/hour). The capacity is the first indicator of thebatteries size. To keep things simple, think of capacity (mAh) as the amount offuel in your cars gas tank. A higher capacity tank will run your car forlonger. A 4,000mAh battery will run for twice as long as a 2,000mAh battery.

A 2,000mahbattery will (in theory) run for 1hr if drained at a constant 2,000 Milliamps.

 

Discharge(C)

Discharge isthe amount of power the battery can ‘push’ out and the number shown ’20C’ is anmultiplication of the capacity. For example; A 20C battery can discharge at 20x 2,000mAh which is 40,000mAh or 40Amps.

This is animportant number if you know your motor requires a certain power level.

In additionto this, batteries have a ‘Burst’ rate, which is the amount of power the batterycan discharge for a short period, usually 10-20 seconds. A typical batterylabel may show 20-30C, this would mean a 1,000mAh battery can discharge20,000mAh constantly or give a sudden and short 10-20 second 30,000mAh (30A)burst of power.

Tip: A higher‘C’ rated battery will last longer if run at a lower ‘C’ rate. Example: a 30Cbattery run at 20C maximum will have a longer cycle life than a 20C run at 20Ceach flight.

 

Voltage (S)

All lithiumPolymer cells in any industry have a nominal voltage of 3.7v per cell. Whenfully charged a LiPoly cell should be 4.2v and when discharged it should neverbe below 3v.

You willnotice that LiPoly RC packs are made up of layers of multiple cells. If thebattery’s rating is 3S this means it is 3 x 3.7v which is 11.1v. It has 3layers of 3.7v each. In other words, its a ‘3 cell pack’.

 

Weight/Size

For abattery to be right for your model it must fit within the models batterycompartment and also balance the plane correctly.

It’s tempingto choose the biggest and most powerful battery your model can handle, but thiswill sacrafice flight performance and if your packs voltage is too high;destroy the ESC or Motor.

Check withyour ESC and Motor specification to ensure you have the right voltage pack thencheck the models CG (Center of Gravity) to decide on the right battery weight.

 

LiPolyCharging

Always use alithium Polymer battery charger and never charge the battery above 4.2v percell. (example: 2S, never above 8.4v)

Never leavea charging battery unattended.

Never allowthe battery’s voltage to fall below 3.2v per cell. (example: 3S, never below9.6v)
