Custom Lithium ion Battery Pack
20 Years Focus On Lithium Ion Battery Pack Customization
18650 battery is the originator of lithium battery. In order to save production costs, SONY formulated a standard battery model in that year, in which 18 represents the diameter of 18mm, 65 represents the length of 65mm, and 0 represents cylindrical battery. The common 18650 battery is divided into lithium ion battery and lithium iron phosphate battery, and the single cell capacity is usually 2200mah-3200mah.
Core Competence
1. Multi - series multi - parallel connection can be composed of different size battery pack.
2. Small internal resistance, high voltage, no memory effect
3. High safety performance, no explosion, no combustion, non-toxic, pollution-free
4. More than 500 cycles, nice high temperature resistance
5. The capacity is 70-80% with more than 500 cycles, which is twice than that of ordinary batteries.
Medical equipment, security monitoring, emergency fire, rail transit, exploration and mapping, instrumentation, 5G Internet, emergency backup, garden tools, solar energy storage, consumer electronics, etc.
Battery Cell Selection + PCM & BMS + Structure Design + Chargers
Cell Selection and Cell Quality Detection
Design of shape and internal structure
Electrical performance design：protection function, accurate power display, host communication, certification, battery set-making, charging
Charger design：External or built-in charger
Mid-term overall re-evaluation
First sample
Basic electrical performance test, and test under different environmental conditions
18650 lithium battery has a large capacity, long cycle life, good safety performance, high voltage, no memory effect, small internal resistance, available series and parallel connection and wide range of application,etc. On the other hand, lithium-ion polymer battery may lead to short circuit or explosion, and the production requirements of polymer battery are relatively high, which undoubtedly increases the production cost for lithium-ion battery manufacturers.
Lithium Battery Advantages
1.Large Capacity
The conventional capacity of 18650 lithium battery is 2200mah-3200mah. LG can make 18650 lithium battery with highest capacity, which achieves 3600mAh, but the price is not low.
2.Long Cycle Life
The life of 18650 lithium battery is very long. It can reach more than 500 times in normal use, which is more than twice than that of ordinary battery.
3.High safety: It’s not easy to cause explosion or environmental pollution.
4.High Voltage
The voltage of 18650 lithium battery is generally 3.6V, 3.8V and 4.2V, much higher than the 1.2V voltage of nickel-cadmium and nickel-metal hydride batteries.
5.No memory effect: no need to empty the remaining power before charging.
6.Small internal resistance: small irreversible volume damage can greatly reduce the power consumption of the battery itself, so as to improve battery life;
7.18650 lithium battery pack can be connected in series or parallel.
