This is a common call we get at Venom, and most of the time it goes like this: “I’m trying to charge my three-cell 5000mAh battery at 5.0A, but it only gets to 3A.” The charger allows you to set the 3S 5000mAh pack to charge at 5.0A, but it never actually gets to 5A. The reason for this is a result of the maximum wattage available in the charger. First, let’s start with the following equation: Volts x Amps = Watts. Let’s say that you want to charge a 3-cell 5000mAh battery at 1C. Calculate that charge rate first by dividing the mAh rating of the pack by 1,000. In this case, we get 5A.
We now need the maximum voltage required to charge that pack. Take 4.2V and multiply it by the amount of cells in your battery. In our example, this would be 12.6V (4.2V x 3 = 12.6V). Multiply the maximum voltage by the charge rate and you’ll get the wattage. In our case, it would be 63W (12.6V x 5A = 63W). So if you were charging with a 50-watt charger, the charge rate would be less than 5A. Let’s now take a look at calculating the maximum charge rate based on the wattage information. For that, we need a new equation, which is: Watts ÷ Volts = Amps.
Using our same example battery (3S 5000mAh LiPo) and keeping our charger at 50W, we get approximately 4A (50W ÷ 12.6V = 4A, rounding up). Remember, we calculate voltage by taking the maximum voltage of 1 cell (4.2V) and multiplying it by the number of cells in the pack (3).
Using the same 50W charger, let’s see what happens when we make the battery a 6S pack. For a 6S pack, the maximum voltage is 25.2V (4.2V x 6 = 25.2V). Plugging the numbers into the equation, we get approximately 2A (50W ÷ 25.2V = 2A). As you can see, wattage plays a large factor in your charger’s ability to charge higher-voltage, higher-capacity packs. By using this information, you can determine what charger will meet your individual charging needs.
We’ve discovered how wattage affects your charge rate and how to calculate the maximum wattage required for the particular battery that you’re charging. On a related topic, we are often asked to compare charger amperage to the amperage in your house. The question goes something like this: “If my wall outlet is only rated for 15A, how can my charger work at 20A?”
The answer to this question is that you can’t compare amps if you are not factoring in the wattage as well. North American homes have 120V at 15A, so using our math equation, the wattage in your home is 1800W (120V x 15A = 1800W). Compare that to your charger charging a 6S LiPo (25.2V) at 20A, which turns out to be only 504W (25.2V x 20A = 504W).

DRONES BECOME SO POPULAR
THE DRONE REVOLUTION
The 21th century has seen the developing of unmanned flying machines that have assumed control over the air space. Gradually however relentlessly, it has now turned into a typical wonder for the military, meteorologists, organizations and specialists to fly them; and we can generally spot them now and again from a separation. These artworks are currently being utilized to dispatch assaults on foes' domains, convey items to clients' doorsteps while additionally utilized as toys for specialists. Be that as it may, there has been open objections in certain nations where automatons have been utilized to keep an eye on different various exercises done in broad daylight, in this manner, undermining their natives' protection. In spite of this, there is the topic of when did automatons turned out to be well known?
HISTORY OF DRONES
Numerous military powers in various pieces of the world have been in the bleeding edge in utilizing automaton assaults on adversaries' domains. The automaton pilots, named "desk area warriors" are being selected at a quicker rate than the conventional stream pilots; who consistently hazard their lives in battle. Early utilization of automatons can be followed back to World War II, where unmanned planes were utilized in the Vietnam War. The Israeli Air Force has been licensed with winning numerous fights with adversaries just by utilizing electronic distractions, jammers and constant video surveillance.
In 1998, the US thought of Endurance Unmanned Crafts, which could keep awake noticeable all around for long. An outstanding accomplishment of these EUC, came when an art named Laima, crossed the Atlantic Ocean in 26 hours. Non military personnel automatons have additionally caught the consideration of numerous flying experts in various nations. For instance, the US gauges that by 2020, their will have in excess of 15,000 automatons keeping an eye on its airspace.
SO WHY ARE DRONES POPULAR?
Engaging Size And Portability
Unmanned art innovation has demonstrated to be equipped for catching essential data from various points; for instance in taping films or catching live occasions. It is said that they may change the fate of news coverage soon.
Fall In Cost Of Technology
Amazon and Dixons have credited the development of automaton deals to their genuinely low costs. Automatons extend from as low as £30 to £30000GBP contingent upon their planned use, battery power and adornments appended to them, for instance a camera.
Sheltered And Quick Capturing Live Events
Most news broadcasting stations are utilizing automatons to catch the most recent live occasions as they occur. It is route less expensive to utilize an automaton in catching a woods fire, than taking a chance with the life of a photograph columnist, while likewise cut on costs that accompany contracting a helicopter that charges on hourly premise.
Guidelines By The Aviation Authority
The prominence of these specialties have brought an objection from people in general since specialists and fear based oppressor will in general use them for sick purposes, in this way, compelling avionics specialists to force guidelines on the utilization of automatons. There have been effective indictments over the abuse of automatons in various nations. Nonetheless, for created economies like the UK, aeronautics controllers and common partners have been united so as to make a comprehension on how the automatons can be utilized to profit everyone, henceforth diminishing occurrences of fear based oppression and abuse of automatons.
