How does this lithium-ion battery work?

Electrochemical reactions occur inside the element. Lithium ions move between the cathode and anode. This creates a flow of electrons in the external circuit. When discharged, energy is released to power the device. When charging, energy is stored back in the element.

The key difference from LiPo is its higher energy density. This means more capacity with the same size and weight. However, the current efficiency of Li-Ion is usually lower than that of LiPo. Therefore, the M35A is chosen for tasks where operating time is important. For example, for long-distance flights or powering equipment.

The technical characteristics of this element are impressive. The nominal voltage is 3.6-3.7 volts. The maximum charging voltage is 4.2 volts. The minimum safe discharge voltage is 2.5 volts. 3500 mAh capacity confirmed by independent tests. Continuous discharge current reaches 10 amperes.

Breadth of use

It can be used in a single element to power low-power devices. For example, for radio equipment or flashlights. More often, several elements are combined into battery assemblies. This allows you to get the desired voltage and capacity for the quadcopter.

To assemble a battery, you need to connect the elements in series or parallel. A series connection increases the overall voltage of the assembly. Parallel connection increases the total capacitance and current efficiency. Often combined schemes are used (for example, 4S2P). This requires soldering skills and the use of BMS protection circuitry.

The quality of the Molicel element ensures its long service life. It can withstand hundreds of charge-discharge cycles without significant degradation. It is important not to allow deep discharge below the minimum voltage. Also, the maximum charging voltage must not be exceeded. Compliance with these rules guarantees safety and durability.

The element has a standard 18650 cylindrical body. The diameter is 18 mm, the height is about 65 mm. The housing has a protective shell against short circuits. The positive contact protrudes slightly, the negative contact protrudes slightly from the body. This is standard for most devices with such batteries.
