li ion 18650 battery pack Processing

　　The difference between 18650 lithium battery and 32650 lithium battery:

　　18650 has been known to the public as the longest lithium battery to be used. The 32650 lithium battery is not very famous in everyone's impression, what is the difference between them?

　　32650 lithium battery

　　One: different weight

　　The 18650 lithium-ion is 18mm, and the 32650 straight is 32mm.

　　Different battery cathode materials

　　The cathode material of 18650 lithium cathode material is usually: ternary, lithium iron phosphate battery, lithium iron phosphate battery, lithium cobalt oxide battery, etc., while the cathode material of 32650 lithium ion battery is usually lithium iron phosphate battery.

　　Three: different working voltage

　　Due to different raw materials and different working voltages, the rated current of the 18650 ternary lithium battery is charged, and the rated current of the lithium iron phosphate battery is charged.

　　Four: different quantities

　　Due to the limited specifications and sizes of 18650, the volume is not easy to be very high, and the general volume is 1800mah-2600mah. Konka can guarantee 3600 Maha, but the price is relatively expensive. However, the volume is 32650mah, the volume can guarantee a maximum of 6500mah, and the general volume is 4500mah-6500mah.

　　Five: different frequency cycles

　　The frequency of the 18650 periodic system is about 800-1000, while the frequency of the 32650 periodic system can go up and down to 2000 years.

　　Six: different processes

　　The relative density of lithium phosphate batteries is lower than that of lithium ion batteries.

　　7: Different internal resistance

　　The general 18650 internal resistance specification is 60 meters, and many manufacturers ensure that 45 meters is within 20 meters. The internal resistance of the 32650 lithium-ion can be guaranteed within 20 meters (without ptc).
