Battsys 14500 3.2V 600mAh LiFePO4 is a safer and more stable battery made from Lithium Iron Phosphate (LiFePO4) chemistry for solar post lights, emergency lighting, alarm systems, medical devices, sports equipment, photographic equipment, telecommunication equipment and more.
14500 lifepo4, belongs to the cylindrical lithium battery, its diameter is 14mm, height is 50mm, according to the core material is divided into lithium iron phosphate and lithium cobalt acid battery. Lithium cobalt acid battery voltage 3.7V, lithium iron phosphate battery voltage 3.2V.
14500 lifepo4, also known as AA batteries, dry batteries, is a common rechargeable battery. Its length and diameter are basically the same as that of a normal size 5 battery (AA battery), but the voltage is higher, usually around 3.7 volts. This is due to its use of lithium-ion battery technology, which provides higher energy density, longer service life, and a smaller self-discharge rate than regular dry cells.
Like other battery sizes, 14500 batteries have positive and negative electrodes, and you need to pay attention to the polarity, otherwise it can cause damage or even danger to your equipment. It is also necessary to choose the right 14500 battery according to the needs of the equipment, including voltage, capacity, charging method and other parameters.
Battsys is the best 14500 lifepo4 manufacturer with high quality, fast worldwide shipping, 3-15 days delivery time, accepting OEM and ODM. its lifepo4 product Excellent safety performance;Long cycle life;Fast charging; Wide temperature range: charging temperature range of 0~60°c, discharging temperature range of-20~65°C.

Learn More3.2v 14500 lifepo4 is widely used in: mobile power supply, amplifier, laptop, digital camera, walkie-talkie, portable VCD/DVD, IC card terminals, electronic door locks, electric toys, emergency lighting, alarm systems, medical equipment, sports equipment, photographic equipment, communication equipment, all kinds of instruments and meters and so on.
1. Ultra-long life: the cycle life of lifepo4 battery reaches more than 2000 times, such as Battsys 14500 lifepo4 more than 2000 times life. lifepo4's service life is far more than that of traditional lead-acid batteries.
2. Safe to use: lifepo4 batteries have completely solved the problem of safety hazards of lithium cobaltate and lithium manganate, and will not explode even in a strong collision, which poses a threat to the life safety of consumers.
3. Rapid charging and discharging with high current: under the special charger, the battery can be fully charged in 40 minutes with 1.5C charging, and the starting current can reach 2C, which is not available for lead-acid batteries.
4. High temperature resistance: lithium iron phosphate can reach 350℃-500℃, while lithium manganese and lithium cobalt only at about 200℃, showing good high temperature performance.
5. Green: Li-FePO4 battery does not contain harmful elements, low cost, in line with the requirements of green environmental protection.
The nominal voltage of a LiFePO4 battery is 3.2V, the termination charging voltage is 3.6V, and the termination discharging voltage is 2.0V.
14500 LiFePO4 is equivalent to an AA battery. 14500LiFePO4 has a diameter of 14mm and a height of 50mm, which are the same dimensions as AA batteries, also known as #5 batteries.
4500 LiFePO4 is equivalent to an AA battery. Although 14500 LiFePO4 is shaped like an AA dry cell, there are significant differences between the two. 14500 cells are longer and wider in diameter than AA dry cells. In addition, 14500 batteries have a much higher capacity, typically 500 mA or more.
The nominal voltage of a LiFePO4 cell is 3.2V, the termination charging voltage is 3.6V, and the termination discharge voltage is 2.0V.
Typically, the capacity of 14500 LiFePO4 is measured in mAh. mAh helps us to gauge how much capacity the battery has and better determine the length of time it can power. If the battery has a capacity of 900 mAh, it means that it can power 900 milliamps of current in one hour. Therefore, how can we calculate the capacity of a battery based on the current value of 14500 LiFePO4 voltage and the working appliance? The formula is as follows: Battery capacity (mAh) = Battery voltage (V) X Current (A) X Time (h) / 1000.
14500 LiFePO4 and 18650 belong to the same type of lithium batteries, both through the model number to indicate the size of the battery. 14500 indicates that the diameter of 14mm length of 50mm cylindrical batteries, its size and the usual size of 5 batteries is the same size; 18650 is the diameter of 18mm length of 65mm cylindrical batteries, this specification of batteries in many occasions are also This size of battery is also very commonly used in many occasions, such as laptop computers, electric cars, flashlights and so on.
These two specifications of the battery according to the different types of batteries will also have different specifications, common lithium iron phosphate batteries and lithium-ion batteries. LiFePO4 batteries rated voltage of 3.2V, saturation voltage of 3.6V; lithium-ion batteries rated voltage of 3.7V, saturation voltage of 4.2V. 14500 LiFePO4 batteries due to the relatively small size, so its capacity will also be relatively small, the conventional capacity is generally used for the battery. will be relatively small, the conventional capacity is generally between 600mAh-800mAh, the largest capacity is generally not more than 900mAh, so the questioner gave the battery capacity of 500mAh is not too small capacity, except that the cost of the battery is too low there may be a capacity of false labeling or has been recycled batteries. 18650 batteries are generally in the conventional capacity of 2000-2600mAh, the highest saturation voltage of 4.2V. The regular capacity of 18650 batteries is generally between 2000 and 2600mAh, the highest can be 3400mAh, of course, there are also lower-cost batteries, the capacity is less than 2000mAh.
When using 14500 lifepo4,, we need to know its advantages and disadvantages in order to better utilize its advantages and cope with the defects.The advantages of 14500 batteries are as follows:
(1), long life: 14500 battery life can be several years or more;.
(2), environmental protection: 14500 batteries can be recycled, reducing environmental pollution of discarded batteries;.
(3), easy to carry: 14500 batteries are medium-sized and lightweight, perfect for carrying.
The disadvantages of 14500 battery are as follows:
(1), need to match the professional charger: 14500 batteries need to have a special charger for charging, otherwise it may lead to over-discharge or explosion and other problems;.
(2), easy thermal runaway: if the 14500 battery is overheated for a long time during use, it may cause safety hazards;.
(3), voltage drop, poor voltage stabilization: the stability of the work is not as good as the No. 5 battery, and the service life is slightly shorter.
