Heated batteries are special batteries equipped with built-in heating elements or temperature control systems that maintain the optimal operating temperature of the battery cells.

Their main purpose is to ensure stable performance in cold temperatures. Conventional lithium-ion batteries lose capacity in the cold, experience faster voltage drop, and may fail to deliver the required current.

In copters, UAVs, and FPV drones, these batteries are used to:

maintain stable motor thrust in cold weather
prevent sudden voltage drops under load
extend flight time in winter
protect the battery from degradation due to overcooling

Thanks to the heating, the battery quickly reaches its operating temperature and maintains it during flight, which is especially important for professional and industrial drones.

What is the 6s3p configuration?

The 6s3p configuration means that the FPV battery consists of six cells connected in series (6s) and three parallel branches (3p). This provides a nominal voltage of 21.6V, a capacity of 12,000mAh, and a peak discharge current of 135A. This format combines high performance with optimal weight, making it an excellent choice for FPV drones that need to withstand intense loads.

Why FPV drones?

The FPV battery is a critical component that determines flight time, power stability, and drone endurance. The 6s3p configuration provides the necessary voltage along with sufficient capacity, making it an optimal choice for FPV drones with higher energy demands. This is especially crucial for combat drones carrying explosive payloads and reconnaissance models operating on challenging routes. Lishen 6s3p batteries excel under peak loads, ensuring steady current and reliable control in the most demanding situations.

Connectors and connections

The battery pack is connected using the XT-60 connector, a proven standard in the unmanned aerial vehicle industry. It provides stable conductivity even under high loads. The XT-60 is designed for currents up to 60 amps in short-term peaks and maintains reliable contact even after hundreds of connection cycles.

A separate wire with an AMASS XT-60H Male connector is responsible for the heating.

Originality and reliability

Our kits use only new, genuine batteries from well-known manufacturers. You can choose from brands such as Molicel, Lishen, and Samsung.

All of them have proven themselves in the FPV segment thanks to their stable current output, reliable capacity, and endurance during flights. These are proven components that have been tested in real-world conditions and have demonstrated high reliability.

Production and capabilities

Our production ensures fast order fulfillment, from single units to tens of thousands.
We design custom battery solutions from scratch and integrate them into your products and infrastructure.

▸Frequently Asked Questions (FAQ)

What is C-rate (Discharge Rate)?
C rate is a technical indicator of current delivery. It determines the speed at which a lithium-ion battery can safely deliver or receive a charge relative to its capacity. For FPV drones and quadcopters, this indicator is important because it affects the manoeuvrability of the drone and its ability to satisfy its power requirements. If we take our 6s 3p Lishen LR2170LA lithium battery with a peak current of 135A as an example, then the approximate C-rate will be approximately 11C. From this, we can conclude that the permissible load is 11 times the capacity of 12000 mAh. In fact, a high C-rate ensures stable power supply and uninterrupted operation for a combat FPV drone.
What is the difference between Li-ion and Li-Po?
Let's start with the fact that both types are lithium batteries, which simply have different chemistry inside. What can be said about lithium-ion? LiIon batteries release energy longer because they have a lower C-rate. Yes, it is not suitable for FPV racing, but on the front line, where longer flights are required for drones such as FPV reconnaissance drones, it is the most suitable option. Now let's talk about LiPo. Lithium polymer (LiPo) is a soft pack, the advantage of which is a higher maximum current output for aggressive flight. This type of battery is suitable for people who are interested in drones as a hobby, which is more common in the West. Our high-current Li-ion assemblies combine energy capacity and sufficient current output of 135A, making them the ‘gold standard’ for impact FPV drones.
What does 6S3P mean?
Although this topic has already been mentioned, let's go into more detail. There are two types of connections: serial and parallel. In fact, the number of different types of connections is called a ‘configuration.’ For example, in our assembly, the configuration of the elements will be 6S3P, where 6S is responsible for the serial connection and 3P for the parallel connection. For drones, the basic configuration is 6S (6 Series). Six serial connections are responsible for the voltage, where each element has a nominal voltage of 3.6 V, giving a total voltage of about 22 V (rounded), which is required for powerful UAVs. Then, depending on the drone used, the battery capacity is selected and parallel connections are added. The designation 3P (3 Parallel) means a parallel connection that triples the capacity and current output: if one cell has 4000mAh, then 3P = 12000mAh.
How to properly charge a 6s3p battery?
This is a really important question. Especially since FPV quadcopter kits do not include a BMS board, which is responsible for safety and balancing the cells. However, the battery has a built-in QJ JST-XH 6S balancing cable for proper battery charging. What is ‘proper charging’ as a definition? Proper charging is the even distribution of energy across the cells, which helps to avoid imbalance in the battery and prevents overheating and overloading. ‘Battery Chargers’ were created to ensure proper charging. These devices usually have standard XT60 or XT30 connectors, as well as a connector for connecting a balancing cable. Next, all you need to do is connect the XT 60 cable and the 6s balancing cable on the battery to the charger, set the charging parameters required by the LiIon battery, and wait for it to charge.
Where to store the battery?
The first thing you need to know is not to store Li-ion batteries fully charged (up to 25.2 V) or fully discharged. The recommended storage voltage is provided by the manufacturer and is labelled ‘Storage Voltage’, which usually means 3.7–3.8 V per cell, i.e. 22.2–22.8 V for a 6S assembly. Storing in ‘Storage’ mode minimises capacity degradation. Now let's talk about how to store rechargeable batteries, more specifically about the temperatures at which they should be stored. Li-ion chemistry requires a cool, dry space (10–20°C), not too cold or too hot, i.e. away from the sun and heat sources, but not in the refrigerator. It is also important to know the consequences if the battery is exposed to unfavourable thermal conditions: in cold weather, maximum capacity is lost and the battery's life is shortened; in hot weather, gas forms inside the cells, causing overheating or, in the worst case, battery explosion.
