The difference between 18650 lithium battery and 32650 lithium battery.18650 battery 1800 mah

　　The difference between 18650 lithium battery and 32650 lithium battery:

　　As the longest-used lithium battery, 18650 has been known to the public. The 32650 lithium battery is not very famous in everyone's mind. What is the difference between them?

　　32650 lithium battery

　　1: Different weights

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

　　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 voltages

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

　　Four: different quantities

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

　　Five: Different frequency cycles

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

　　Six: different processes

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

　　7: Different internal resistances

　　The common 18650 internal resistance specification is 60 meters, and many manufacturers ensure 45 meters within 20 meters. The internal resistance of 32650 lithium ion can be guaranteed to be within 20 meters (no PTC).
