Original Molicel P50B 21700 3.6V 5000mAh Cylindrical Cell On Sale

Original Molicel P50B 21700 3.6V 5000mAh Cylindrical Cell On Sale

• High capacity: Its nominal capacity is 5000mAh. The large capacity allows the device to be used for a long time after a single charge. Whether it is outdoor adventure or daily use, it can reduce the frequency of charging and reduce power anxiety.

• Good high-rate discharge performance: The maximum discharge current is up to 45A, which can easily meet the high current requirements of various high-power devices such as drones and photography lights. The discharge process is smooth and the voltage is stable, which can ensure that the device is in the best working condition.

• Excellent low-temperature performance: It can work normally in a low-temperature environment of -40℃. Compared with many batteries that are unstable in power supply below zero, it can keep the device active in cold weather or low-temperature environments, greatly expanding the use scenarios.

• Long cycle life: The cycle life is about 800-1000 times. It can still maintain good performance after multiple charge and discharge cycles, reducing the long-term use cost.

• Low internal resistance: The internal resistance is only 9mΩ±5. The low internal resistance can reduce the energy loss of the battery during the charge and discharge process, improve the charge and discharge efficiency, reduce heat, and extend the battery life.

• High safety: It uses a lithium-ion chemical system with good chemical stability. At the same time, from product design to production process, there are a series of safety measures, such as overcharge, over-discharge, and overheating protection, to ensure safety and reliability during use.

Key Features

• High energy density: Ternary materials (nickel-cobalt-manganese or nickel-cobalt-aluminum) give the battery a higher energy density, which can store more electrical energy in a smaller volume and weight. For example, it can be used in electric vehicles to increase the range, and in drones to extend the flight time.

• Excellent high-rate charge and discharge performance: It can achieve high-current charge and discharge, meeting the high-power operation requirements of the equipment. For example, electric racing cars can quickly output large currents to provide strong power when accelerating, and power tools can also rely on their high-current discharge to maintain efficient operation when working under high load.

• Long cycle life: Under reasonable use and charging and discharging conditions, it has good cycle stability and the number of cycles can reach more than 1,000 times. With the development of technology, the cycle life of some new ternary high-rate batteries has been further improved, reducing the cost of use.

• Good low-temperature performance: Compared with some other types of batteries, the performance degradation is relatively small in low-temperature environments, and it can maintain a certain charge and discharge capacity and output power at -20℃ or even lower, so that the equipment can still be used normally in cold areas or seasons.

• High output voltage platform: The output voltage is relatively high and stable, which can provide a more stable power supply for the equipment, reduce the impact of voltage fluctuations on equipment performance, and improve the stability and reliability of the equipment.

Applications

P50B has the advantages of high capacity, high discharge rate, and good low temperature performance, so it is widely used, mainly including the following fields:

• Power tools: such as electric drills, electric planers, angle grinders, etc. P42A can provide strong and stable power to meet the high current requirements of tools when working under high load, so that they can operate efficiently, and can also allow the tools to be used normally in cold environments, reducing the performance degradation caused by low temperature.

• Drones and rc model: Whether it is a civilian drone or a model airplane, the battery needs to have high energy density and high discharge rate. P42A can support drones to take off quickly, hover and fly at high speed. Its large capacity can extend the flight time, and its good low temperature performance ensures stable power supply under different environmental conditions and adapts to various flight scenarios.

• Medical devices: Some medical devices that require portability and endurance, such as portable medical testing equipment, wearable medical devices, etc., P42A batteries can provide reliable power support for them to ensure that the equipment will not be affected by insufficient power during use.

• Lighting equipment: For lighting equipment such as photographic lights and powerful flashlights, when high brightness output is required, P42A can provide sufficient current to ensure the stability and brightness of the light, and can also work normally in low temperature environments, suitable for outdoor adventures, emergency rescue and other scenes.

• Electric vehicles and hybrid vehicles: Although electric vehicles usually use larger battery packs, high-performance cells such as P42A can be used as components of small electric vehicles or hybrid vehicle battery packs, providing high power output, helping vehicles accelerate and climb, etc. At the same time, its low temperature performance also helps to improve the vehicle's endurance performance in cold areas.
