18650 lithium battery assembly 72v50ah method

18650 lithium battery assembled into a 72V50Ah battery pack needs to take the following steps:

Determine the number of batteries needed: A 72V battery pack requires 20 batteries in series (the voltage of each battery is 3.6V), and 5 batteries in parallel (the capacity of each battery is 10Ah).

Purchase a suitable 18650 battery: choose a 18650 battery with a capacity of 10Ah, and ensure that the battery brand, model, voltage, and capacity are consistent.

Test the battery: test the voltage and internal resistance of each 18650 battery, and screen out batteries with similar voltage and internal resistance to form a battery pack.

Connect batteries in series: connect 20 batteries in series, and make sure that the positive and negative terminals of each battery are connected correctly to avoid short circuits.

Connect batteries in parallel: Connect 5 groups of 20 series batteries in parallel. When connecting, make sure that the positive and negative poles are connected correctly to avoid short circuits.

Perform battery packaging: Assemble the battery in the appropriate battery packaging box to protect the battery and ensure safety.

Perform battery test: Before use, the entire battery pack needs to be tested to ensure that it works properly and meets the design requirements.

Advantages of portable medical lithium batteries?

Portable mobile electronic products are becoming more and more convenient. Many industries are gradually paying attention to the mobility of products, and the field of medical equipment is no exception. A few years ago, professional medical personnel could not save lives at the scene far from the hospital, and they could not bring medical equipment to the scene. At that time, the technology of portable instruments was not yet mature. Nowadays, due to the continuous development of lithium battery technology, medical devices such as monitoring instruments, ultrasound imaging equipment, infusion pumps, and cardiac pacemakers can be used anytime and anywhere. Portable medical equipment has become an important field of modern medical care, and medical equipment has stricter requirements on batteries. Compared with other traditional technologies, lithium batteries have many advantages in the application of portable medical equipment. Portable medical lithium batteries What are the advantages?

Good safety performance: For medical equipment, safety is of course the first priority. The lithium battery structure dedicated to medical equipment generally uses aluminum-plastic flexible packaging. This packaging can prevent lithium batteries from exploding and burning, greatly improving safety. sex.

Large capacity: Compared with other types of batteries, lithium batteries have larger capacity.

The internal resistance is very small: through special design, the impedance of the lithium battery can be greatly reduced, the high-current discharge performance of the lithium battery can be greatly improved, and it can meet the needs of high-rate discharge medical equipment.

Ultra-thin thickness: The thinnest liquid lithium-ion battery can be less than 5mm, so there is no technical bottleneck in the medical field, and it can meet various medical equipment.

The shape can be customized: due to the particularity of medical equipment, lithium batteries can meet special customization, and the thickness and shape of the battery can be changed according to different medical equipment to meet the use.

Very light weight: the lightness of the lithium battery makes it a favorite of portable medical equipment. While satisfying the use, it reduces the quality of medical equipment and is more convenient to use.

Therefore, I recommend TEFOO ENERGY standard lithium battery, which is convenient for operators to carry out mobile indoor and outdoor operations. Providing continuous, efficient and stable mobile power supply has become the greatest guarantee for the normal operation of such equipment. The solution uses high-performance batteries, so that the entire battery has the characteristics of high energy ratio, light weight, small size, high cycle life, high safety, and high consistency. The battery is very convenient to use, and the original battery can be directly replaced on site.
