When choosing a battery, a sacrifice must be made between the battery size and the weight. A higher milliamp rating on a battery essentially means that it will provide more flight time per charge. As an example, a 1500mAh battery would be able to supply: 1500 milliamps (1.5A) of current for an hour, 3000mA (3A) of current for a total of 30 minutes, 6000 mA (6A) for 15 minutes and so on. Exotic setups such as 5S 150mm racing quadcopters or 2S micro brushed quadcopters do exist however they are just quite uncommon.īattery capacity is measured in milliamp hours (mAh) which is a unit describing the current a battery can supply for a unit of time. It is important to note that the quadcopter applications listed in the following table are only typical examples from the many different battery-quadcopter combinations in existence. The following table summarizes the voltage and common applications for various LiPO cell configurations. For this reason, 4S LiPO’s are the most commonly used for racing quadcopters as they provide a balance between speed and weight. This is explained further here but simply, more battery voltage allows the motors to spin with greater speed (RPM). The battery pack voltage is important as it impacts the maximum motor speed of a quadcopter. The more cells that are grouped together, the more voltage the overall battery pack will have. LiPO packs are commonly sold in 1S, 2S, 3S, 4S, 5S or 6S configurations where the digit followed by the ‘S’ stands for number of cells in that specific pack.

A standard lithium polymer cell has a nominal (storage) voltage of 3.7V hence to increase the power that a single LiPO pack can deliver, these cells are grouped together in series (meaning the ground/negative lead from the first cell is connected to the positive lead of the next cell, forming a chain of individual cells) to increase the overall battery pack voltage. A higher FPV Drone Battery voltage allows the pack to provide more power to the quadcopter without increasing the current or amp draw. LiPO packs are the most commonly used across all sizes of quadcopters however LiHV packs are quite popular for use on “Tiny Whoop” micro drones because the extra voltage moderately improves the quadcopters performance.īattery voltage is the potential energy difference between the positive and negative terminals. In regards to the performance of the two packs, a LiHV battery will initially provide more power but abruptly drops in voltage when discharged whereas a LiPO has a more linear discharge making it easier to qualitatively gauge the remaining flight time. A LiPO has a resting or nominal voltage of 3.7V versus a LiHV which has a storage voltage of 3.8V.

The primary difference between the two is that a LiPO cell has a fully charged voltage of 4.2V compared to a LiHV cell which has a voltage of 4.35V at full charge. The lithium battery packs used to power quadcopters have two common chemistries: Lithium polymer (LiPO) and lithium polymer high voltage (LiHV). By then end of this article, you should be able to observe and understand any quadcopter battery label and have the information required to make an informed decision when selecting quadcopter batteries. This article will discuss the differences between various lithium batteries, battery specifications and also provide some basic recommendations.
Lithium batteries are the most common battery chemistry used to power quadcopters due to their high energy densities and high discharge capabilities. An FPV Drone Battery is the foundational component of a quadcopter and must be considerately selected to achieve an ideal balance between performance and flight time.
