A Li-polymer battery is a type of rechargeable lithium-ion battery that uses a polymer electrolyte instead of a liquid one. This design enhances flexibility, safety, and energy efficiency compared to traditional lithium-ion batteries.

LiPo batteries have a nominal voltage of 3.7V per cell. Multiple cells can be connected in series to achieve higher voltages, such as 7.4V (2S), 11.1V (3S), 14.8V (4S), etc. The choice of voltage depends on the power requirements of the application.
The capacity of a LiPo battery, measured in milliamp-hours (mAh), determines how much energy it can store. Higher capacity batteries provide longer operating times. Buyers should select the appropriate capacity based on their device’s energy consumption.
The C-rate indicates how quickly a LiPo battery can release energy. A higher C-rate is essential for power-hungry applications like drones and RC cars, where rapid bursts of power are required.
The number of charge cycles a LiPo battery can endure before degrading is an important factor. Proper charging practices, including using balance chargers and avoiding overcharging, can extend battery life.
LiPo batteries require built-in safety mechanisms to prevent overcharging, over-discharging, and short circuits. Buyers should look for batteries with protective circuitry and high-quality materials.
A reliable manufacturer ensures consistent quality and timely deliveries. Buyers should assess suppliers based on production capabilities, delivery timelines, and quality control processes.
LiPo batteries must meet international safety and performance standards. Essential certifications include:
Depending on the application, buyers may need specific dimensions, voltage ratings, or connector types. Some manufacturers offer customization services to meet these needs.
While cost-effectiveness is important, buyers should balance price with quality. Low-cost batteries with poor quality can lead to safety risks and shorter lifespans.
Different countries have regulations on battery disposal, recycling, and transportation. Buyers should ensure compliance with local laws to avoid legal issues.
LiPo batteries provide high discharge rates and lightweight power solutions, making them ideal for drones, radio-controlled (RC) cars, and aircraft.
Smartphones, tablets, smartwatches, and wireless earbuds use LiPo batteries for their slim design and long battery life.
Cordless drills, saws, and other power tools benefit from high-capacity LiPo batteries that deliver reliable power.
Portable medical devices such as defibrillators and patient monitoring systems require safe and long-lasting LiPo batteries.
LiPo batteries enable industrial robots and automation systems to operate efficiently with minimal downtime.

LiPo batteries play a crucial role in modern electronics, offering high energy density, lightweight design, and flexible configurations. For bulk buyers, understanding key performance indicators, supplier reliability, and industry applications is essential.
If the customized information provided by the customized lithium polymer battery is incomplete, it will not only affect the work efficiency but also cause misunderstanding of poor working ability. More importantly, it may cause a large safety hazard to the product, so GREPOW is for the lithium polymer battery. Customization summarizes a few experiences for battery customers to refer to, whether it is to do project product design or custom battery solution report will be very helpful.
Because the polymer battery generally adopts single-folding or double-folding technology, the battery edge will be loosened when the battery is folded. For example, the original folding edge is 20mm wide, and the flange will be loosened after the folding. 20.3mm or so, don't worry about it at this time, this is also the time to test the product designer, remember to leave more space or leave battery space.
Since the polymer battery itself has expansion property, all the soft pack batteries will expand after being charged and discharged for a certain number of times, so the thickness expansion ratio should be considered in the design of the product, and the force and force card of the caliper card battery thickness is used, and the thickness is There will be changes, do not believe that you can find a lithium polymer battery caliper to test the thickness, at least 10 wire thickness deviation.
Most of the digital products use ternary battery material systems, such as mobile phones, tablet computers, Bluetooth headsets, etc., while the high-capacity polymer batteries used in vehicles use more lithium iron phosphate systems; the ternary materials are normally 3.7V. The voltage, while the iron-lithium material is 3.2V.
A certain capacity can be achieved in the corresponding battery space, but not 100% of this battery capacity segment, so the custom battery manufacturer will give the upper and lower limits of the battery capacity; for example, when evaluating the manufacturer The design capacity given is 100mAh, and 95mAh will appear in the actual production process. These are normal, because the design will have positive and negative tolerances, so don't bite the word to lift it.
High voltage and common voltage must be distinguished. For example, when using a high voltage 4.35V (full charge) voltage system, it must be clearly stated in the specification of the lithium polymer battery, and the ordinary voltage is 4.2V (when fully charged). If you do not explain clearly that we will generally customize the 4.2V voltage system, it is recommended that you understand the power supply scheme of your product chip to see what voltage system is suitable.
For example, some Bluetooth headset batteries have a relatively small operating current. Generally, 0.2C discharge is enough; while the RC battery operating current is generally about 10A. For example, a 600mAh battery for a model airplane can continue to be discharged at 20C. Use on, so be sure to know the working current when customizing the battery, it is best to continue how many A, how much A current to work instantly.
The lithium-polymer battery should pay attention to the overall size of the battery, especially the positive electrode ear size of the polymer battery, because the positive electrode of the soft pack battery is particularly fragile, and it is easy to break when folded several times. Generally, the positive electrode is laser-transferred to nickel, when in use. According to experience, the number of bending of the positive ear should not exceed 3 times. If the battery capacity is large enough, a thick and wide lithium polymer battery customized solution can be used to solve the problem of easy breakage of the ear.
Generally, the output of small polymer batteries is mostly wire, and some of them are output terminal wires of the battery, which involves the corresponding types of terminals, such as JST terminal, PH terminal, 1.25 terminal, 2.0 terminal, 2.54 terminal, 3.96 terminal, etc. Etc., the other terminals are also positive and reverse. If the wrong direction is connected, the product will not work and even burn out the product. If you are not sure, you can provide the plug-in socket and battery power input circuit to the other party, or face-to-face communication. Basically, it can ensure that the lithium polymer battery can be customized in one time without error.
Most of the PACK finished batteries are equipped with protective plates, wires, plug wires, casings, etc., and some special ones may need to add FPC soft cable, such as Apple mobile batteries, some need to add plastic shell, such as walkie-talkie battery; Others need to add communication protocols, such as battery for vehicles; so these items must be clear in the process of customizing the lithium polymer battery, involving high current, shell and shell color, silkscreen, communication protocol, etc. The content is more detailed, the better, the more detailed the more can reduce the mistakes.
Do not deliberately scratch the surface of the battery, because the surface of the lithium polymer battery is very fragile and it is easy to scratch if accidentally. The quality of the customer should not scratch the surface of the battery with the fingernails during the incoming inspection. We should put an end to these unnoticed behaviors. Please support all manufacturers of lithium polymer battery custom, please communicate more details, more inclusive, more cooperation. I hope this article can help customers with customized battery. Of course, these can be extended to other products. I hope that the 10 factors of lithium polymer battery customization will be inspiring.
