1. Voltage and current.

The monomer cathode material is ternary or lithium cobalt oxide lithium battery, and the full charge voltage is 4.2V (high voltage is

4.3V-4.35V-4.4V-4.45V), 2.75V after discharge.

The normal current of charging and discharging is 0.2C-0.5C, and the capacity of the battery is qualified to be established at 0.2C charging and discharging

On the basis of.

Fully charged to 4.2V and then discharged to 2.75V (3.0V), the intermediate process is a cycle. Normal battery

The capacity retention rate is above 80% after 300 cycles. There are also customers who ask for 500 cycles will be more than 300

The price of the secondary cycle is about 3-5% more expensive

2. Parallel and series connection.

Batteries are divided into single cells and battery packs. The battery pack is divided into several strings and together to increase the capacity, strings in one

To increase the voltage. FOR EXAMPLE, 18650 BATTERY 11.1V-5000mAh IS 6 OF 3S2P (3 STRINGS 2 PARALLELS).

18650-2500mAh battery pack.

3. The temperature environment of lithium battery

Most batteries are not rechargeable below 0 degrees (now there are cells that can be charged below 0 degrees, needed. )

Specially procured) will have an impact on the safety of the battery. The temperature of the charge is between 0-10 degrees and the maximum charging current

Is 0.2C current. There is no problem with a normal discharge temperature below 60 degrees.

(See the description above our lithium battery specification for details)

When customers need to use batteries in extremely low temperature or high temperature environments, they can be customized.
