In the evolving world of e-mobility, the choice of battery can make or break the experience. Of the many options available, 72V lithium-ion batteries have become mainstream, revolutionizing the way we power e-mobility and industrial equipment.
Why 72V Lithium Batteries Stand Out
Performance - Oriented Design
In the realm of electric travel, voltage and capacity are the key determinants of an equipment's performance and endurance. The 72V lithium battery, with its high - voltage platform and large - capacity design, has become the go - to power source for electric bicycles, electric scooters, and electric motorcycles.
Compared to traditional lead - acid batteries, 72V lithium batteries offer significantly longer battery life. The 72V system provides a more stable power output, and when combined with high - capacity original Samsung 21700 battery cells, a single charge can support 50 - 80 kilometers of riding, depending on the model and load. This extended range is a huge advantage for daily commuters and those who love long - distance rides.
Lightweight and Compact
Another major advantage of 72V lithium batteries is their lightweight and compact nature. Lithium batteries are only about 1/3 the weight of lead - acid batteries and have a smaller size. This makes them highly suitable for a wide variety of equipment, as they do not add excessive weight, which could otherwise affect the vehicle's handling and energy consumption.
Environmentally Friendly and Long - Lasting
72V lithium batteries are also more environmentally friendly. They can achieve more than 1,000 charge - discharge cycles, reducing the frequency of battery replacement. This not only saves consumers money in the long run but also significantly reduces pollution to the environment.
BOOANT 72V Lithium Battery: A Technological Marvel
Samsung 21700 Cells: A Perfect Blend of Energy and Safety
BOOANT 72V lithium battery is based on Samsung 21700 cells, which strike a perfect balance between energy and safety. The high - energy density of these cells is remarkable, with a single cell capacity reaching 5000mAh. This ensures that the battery pack can provide an ultra - large available capacity, powering high - performance electric vehicles.
For different power requirements, BOOANT uses different types of Samsung 21700 cells. A single Samsung 21700 50G cell can support continuous 10A discharge, meeting the instantaneous power needs of high - power equipment.
For even higher - power motors, the Samsung 21700 50S cells are used, which can support continuous 15A discharge. All battery packs from BOOANT use original Samsung cells, ensuring high battery quality, strong thermal stability, and reduced risk of spontaneous combustion.
Safety - First Design
Physical Protection: The metal shell of BOOANT's 72V lithium battery is designed with safety in mind. It is made using CNC one - piece molding technology, which gives it high structural strength. This allows it to effectively resist riding vibration, falling collisions, or external object extrusion. The metal layer, with a thickness of 0.8 - 1.2mm, also features an anti - puncture design, preventing sharp objects like stones and branches from directly piercing the battery cell and avoiding internal short circuits.
Heat Dissipation Management: Heat is a major enemy of batteries. The metal shell of BOOANT's battery has a thermal conductivity more than 100 times that of plastic (aluminum alloy is about 237W/m・K), allowing it to quickly export the heat generated by the battery cell. The internal thermal conductive silicone and the metal shell form an efficient heat dissipation path, keeping the temperature difference of the battery pack within ±2℃, thus reducing the risk of thermal runaway.
Environmental Adaptation: The battery has an IP65 waterproof and dustproof rating. Through an O - ring + ultrasonic welding process, the metal shell reaches this high - level protection (water spray + dustproof). In extreme scenario tests, after being immersed in a simulated rainstorm (100L/m²・min) environment for 30 minutes, the BOOANT battery still had an insulation resistance of >100MΩ, demonstrating its reliability in harsh weather conditions.
Safety Enhancement: In the event of thermal runaway, the metal shell acts as a fire barrier, delaying heat conduction and reducing the flame spread rate by more than 70%. The internal pressure relief valve, in cooperation with the metal shell, controls the internal pressure peak below 0.5MPa (compared to plastic shells, which usually have a peak pressure >1MPa), providing an extra layer of explosion protection.
Long - Term Durability: The surface of the battery undergoes an anodizing/electrophoresis process, forming a 3 - 5μm protective film. This gives it excellent corrosion and oxidation resistance, with a salt spray resistance test up to 500 hours, far exceeding the industry standard of 240 hours. The metal materials also maintain a dimensional change rate of <0.1% at extreme temperatures from - 40℃ to 85℃, ensuring structural stability and avoiding poor contact due to thermal expansion and contraction.
Smart BMS System
BOOANT 72V lithium battery comes with a built - in smart battery management system (BMS). This system is crucial for ensuring battery safety through multiple protection mechanisms. It provides overcharge/over - discharge protection, automatically cutting off abnormal charging or discharging to extend the battery's lifespan. It also offers short - circuit/over - current protection, constantly monitoring the current to prevent any danger caused by circuit failures. Additionally, with Bluetooth interconnection, users can view the battery's voltage, capacity, and charge - discharge status in real - time through a mobile phone APP, providing convenience and peace of mind.
Industrial - Grade Design
The 72V lithium battery from BOOANT features an industrial - grade design to cope with harsh environments. Its IP65 waterproof and dustproof rating makes it suitable for complex scenes such as riding in rainy days and on muddy roads. The metal shell, made of lightweight yet impact - resistant material, protects the battery cell from external damage. The seismic structure reduces the impact of riding vibration on the inside of the battery, ensuring long - term stable operation.
Versatile Application Scenarios
The 72V lithium battery is incredibly versatile and can be used in a wide range of applications.
Electric Bicycles and Motorcycles
For electric bicycles and motorcycles, the 72V lithium battery provides strong climbing ability, making it easier to tackle hilly terrains. It also meets the needs of long - distance riding, allowing riders to explore further without worrying about running out of power.
Electric Scooters and Balance Cars
In electric scooters and balance cars, the high - voltage output of the 72V lithium battery improves acceleration performance and maximum speed. This enhanced performance makes these vehicles more fun and efficient for short - distance urban travel.
Industrial Equipment
Industrial equipment such as sweeping robots and transport vehicles can also benefit from 72V lithium batteries. These batteries support long - term continuous operation, ensuring that industrial processes run smoothly without frequent battery replacements.
In short, 72V lithium batteries, especially batteries like BOOANT, combine high performance, safety, and durability.
