Lipo Battery Guide

What's a Lipo battery?

Lipo Battery, its full proper noun is lithium polymer battery, people also called Li-po bombardment, or more correctly lithium-ion polymer bombardment (abbreviated as LiPo, LIP, Li-poly and others). Lipo is a rechargeable battery of lithium-ion technology using a polymer electrolyte instead of a liquid i. Loftier electrical conductivity semisolid polymers form this electrolyte. These lipo batteries provide a higher specific energy than other lithium-battery types. It is a newer type of battery at present used in many consumer electronics devices. They take been gaining in popularity in the radio command manufacture over the terminal few years, and are at present the nearly popular choice for anyone looking for long run times and high power.

LiPo batteries offer a wide assortment of benefits. But each user must decide if the benefits outweigh the drawbacks. For more and more people, they do. In my personal opinion, there is goose egg to fear from LiPo batteries, and so long every bit you follow the rules and care for the batteries with the respect they deserve.

This guide is mainly introduce the bones Lipo battery knowledge about Lipo Battery Parameters, Lipo battery'southward choice, Lipo battery's maintenance, Lipo bombardment's safe and Gens Ace Tattu Lipo bombardment's Service.

Lipo Battery Parameters Introduction

We tin can see there are some Parameters on this Lipo battery, they are Bombardment Capacity, Battery Voltage, Cell Configuration and Discharge Rate, our guide will introduce what are these parameters represent?

Prison cell Configuration

A battery is synthetic from rectangular cells which are continued together to grade the battery. A cell which can be considered a battery in itself, holds a nominal voltage of 3.7V. By connecting more than of these in series, the voltage can increase to 7.4V for a 2 cell battery, 14.8V for a 4 cell battery and so on. By connecting more batteries in parallel the capacity tin be increased. Often you lot will encounter numbers like 3S2P, which mean the battery as 4 cells (4S) continued in series, and in that location are 2 cell sets connected in parallel (2P) , giving a total number of 6 private sells in the bombardment. So the number of cells is what defines the voltage of the battery. Having a higher voltage means the battery can provide more power to drive bigger motors, all the same more power does not necessarily mean the battery volition provide energy for longer, that is defined by the bombardment capacity.

Battery Voltage

A LiPo cell has a nominal voltage of three.7V, and a lipo jail cell = 1 cell = 1S = 3.7V. For the 14.8V battery in a higher place, that ways that there are iv cells in series (which means the voltage gets added together). This is sometimes why you will hear people talk about a "4S" battery pack – it means that there are 4 cells in Series. So a 4-jail cell (4S) pack is 14.8V, a three-jail cell (3S) pack is 11.1V, then on.

3.7V bombardment = 1 cell x 3.7V= 1S battery
7.4V battery = 2 cells x three.7V= 2S battery
11.1V battery = 3 cells x 3.7V= 3S battery
14.8V battery = four cells x 3.7V= 4S battery
xviii.5V battery = 5 cells ten iii.7V= 5S battery
22.ii V battery = 6 cells x iii.7V= 6S bombardment
29.6 V battery = eight cells 10 iii.7V= 8S bombardment
37.0V battery = x cells ten 3.7V= 10S battery
44.4V battery = 12 cells 10 iii.7V= 12S battery

The voltage of a Lipo bombardment pack is essentially going to determine how fast your vehicle is going to get. Voltage directly influences the RPM of the electric motor (brushless motors are rated by kV, which means 'RPM per Volt'). So if you take a brushless motor with a rating of 3,500kV, that motor volition spin three,500 RPM for every volt you lot utilise to it. On a 2S LiPo battery, that motor will spin around 25,900 RPM. On a 3S, it volition spin a whopping 38,850 RPM. Then the more voltage you lot take, the faster you lot're going to go.

When you select lipo battery, you need to know your motor of rc model, Voltage has an impact on motor, and motor influence the speed. The college voltage is, the higher power( P) of the motor is, and here is the formula:

P=U*I

"P" is ability, "U" is voltage, "I" is electric current. As you know, the voltage influence the ability of the motor of battery, and the power has an touch on the RPM of the motor, that means speed. Then in some racing, pilots demand the batteries are of high voltage to see the needs of their rc model to get a high outburst.

Battery Capacity

The 1300mAh on the picture means the capacity of the lipo battery. Capacity is used to measure how much power a battery can concur.and the unit of capacity is milliamp hours (mAh), which means 1300mAh tin can be put on the battery to discharge it in one hour. Milliamp too can be converted to amps(A), here is the conversion:

1300mAh=1.3 Amp Hr(1Ah)

By and large, capacity can determines how long you can run before y'all have to recharge. A larger chapters pack may give you longer flight times but being heavier it will adversely affect functioning. Simply it`s also influenced by the speed, the more quick you tin flying your plane, the less time your flight fourth dimension is. Because high speed means you need more than power to drive your plane or others, so your ability lost quickly.

Discharge Rating

Discharge Rate ("C" Rating) is but how fast a battery can be discharged safely. In the RC LiPo bombardment world information technology is called the "C" rating. A bombardment with a discharging rate of 95c, that means you could safely depict it at the 95 times more the capacity of the pack, a 10C pack = 10 times more, a 20C pack = 20C times more, from above the picture, yous can discharge at 95 times more than than 1300mAh, hither is the calculation below:

95C = 95 x Capacity (in Amps)=95*1300mAh=123500mAh=123.5Ah

From the theoretical stand point, if you discharge yous battery at a 2600mAh, so the 1300mAh of battery pack tin be wearied in one-half an hour. From above the calculation, draw battery at 123.5Ah, so this bombardment pack will be describe out in 0.63 minutes.

Sometime, y'all would be required to get a battery of loftier discharging charge per unit, usually in a race, such as FPV racing, you must in a high speed and win a race. So the higher "C" rating means your matter can go a higher flare-up in a moment. So, yous know, why so many pilots attach such a great importance into the high discharge charge per unit. But the disadvantage of the high "C" rating is it may get heavier and affect its performance. And information technology may more than expensive than the lower one.

How to choose a Lipo battery?

Our Lipo batteries are mainly used for RC hobbies, like RC cars, Drone/UAV, RC Airplane/Heli and FPV. In order to get the best flight or running fourth dimension and performance it important to know how to go most choosing the all-time Lipo bombardment.

Like near components on a drone or car, they are related to other components, and the battery is no exception. The correct battery mainly depends on the size of your drone or automobile, and the type and number of motors you use. In this guide we will discuss how to ensure your battery will work properly with your drone or auto arrangement before you purchase it.

Knowing what size battery yous demand

To become the longest flight or running times y'all should use the largest battery (in terms of capacity) that you possibly can(but all the same continue within the maximum takeoff weight of your drone). The other thing to take into account is the concrete size of the battery, as depending on what drone or automobile you are using you volition only demand be able to fit a battery of a sure size.

Battery Discharge Rate and Capacity

Probably the nearly important, merely often overlooked factor to is the check the bombardment discharge C rating is the optimum for your drone or car. Using a belch rate (C rating) that is too low, tin result in your bombardment being damaged, and your drone or car under-performing the battery deceit release current fast plenty to power your motors properly. Since college C rating batteries are heavier, if the battery you are using has a C rating that is too high, you will just be conveying extra weight around that you dont need, ultimately reducing the running time.

How to summate the maximum continuous current output for your battery

In order to know what the total electric current draw of your drone organization is, we cab calculated it based on this simple formula:

Max continous Amp draw (A)= Battery capacity (Ah) x Belch charge per unit (C)

For a example, we have a 5100mAh 3 cell Lipo battery with a 10C rating. To find the maximum continuous amp describe, we beginning convert the 5100mAh to 5.1Ah, and multiply that number by 10C, to give a total continuous output of (v.1 x 10) = 51A

How to find the optimum C rating

As choosing the battery is ofttimes the concluding step to edifice your own drone, we volition already know what motors and ESC we are using. Since the motors will draw the most amount of energy from your bombardment we tin base our calculation effectually this.

The battery C rating depends on the capacity

At that place is no fixed C rating that yous will need to use as the maximum current output of a battery depends on the capacity and C rating. Typically the smaller the capacity of a battery, the higher the C rating needs to be, this is why for many high capacity multi-rotor batteries you volition find very low C ratings in the range of 10-15C.

How much capacity exercise I need?

Now that you know the required current depict from your battery, the capacity and C rating can be found. In general its best to get teh highest possible chapters battery that you tin can, which withal keeping the full weight of your quadcopter including the bombardment and other equipment at aroung 50-70% of the maximum motor thrust.

So sticking to our quadcopter example, nosotros know that 50% thrust is effectually 500g per motor (or 2Kg thrust in total). Our frame, electronics and motors weight come up to i.2Kg. That leaves 800-1000g that we can use for the bombardment. So you should try to find the highest capacity LiPo that you can find that weights less than this.

Bombardment Voltage

The battery voltage, or jail cell count is another important decision that you will need to make. College voltage batteries permit your motors to produce more power, however the higher voltage batteries are heavier since they contain more cells.

There is no golden rule to follow when it comes to battery voltage, but the way you can find the all-time voltage for your drone is to look through your motor thrust information tables and compare the efficiency. Yous will find that motors are by and large more than efficient and powerful when using higher prison cell count lipos (college voltage), but some of the efficiency bonus is negated by the increase in weight and cost of the bombardment. So depending on how many motors y'all are using you lot will need to choose what is best for your electric current setup.

1 affair to conduct in mind is to also brand sure that your motors/ESC and other electronics are able to support the voltage of your battery. Some motors will only support a specific jail cell count lipo, or a specific range of voltages which might brand the decision easier.

Battery Connectors

Soldering battery connectors can be a real pain, so it is a good thought to effort observe a battery connector that you like, and stick to it. That allows you to bandy batteries easily, and if you decide to build another drone in the future you lot can use the same batteries. Common connectors include Deans/Tplug, XT60, and besides EC3 connectors.

Number of batteries

The number of batteries you decide to apply on your drone does not ultimately make much difference equally there are pros and cons of using more batteries. Firstly using more batteries has an added layer of safety equally if one battery should neglect, yous yet have some other that you tin use to quickly land. Also if y'all have the flexibility of replacing 1 bombardment if i of them gets older than the other. Charging time tin be reduced if you have two chargers as each one tin charge at the same time. All the same using two batteries tin can exist more complex to mount and wire and buying two batteries can sometimes be more expensive than buying 1. And then ultimately using one ore more batteries comes down to the drone your are using and your own preference.

Afterward read this guide, you may know how to choose Lipo bombardment, our website recommend you some Lipo battery, if you demand to buy Lipo batteries, y'all tin accept a look.
