After using the 42V lithium battery for 2 months, it can only be charged up to 40V. Why?

Introduction The 42V lithium battery can only be charged up to 40V after using it for 2 months. ① Is your battery a lithium iron battery or other battery system?

After using the 42V lithium battery for 2 months, it can only be charged up to 40V. Why?

① Is your battery a lithium iron battery or another system battery? If it is a lithium iron battery, it is normal.

②After the battery is fully charged, disassemble the battery and test the cell voltage. When fully charged, it will be 4.2V (4.1V is also normal)

③The protection board is. damage and the battery is damaged.

④The protection board and battery are very bad

There are few companies that make better lithium batteries for electric vehicles, I hope they make them will adopt.

What is the difference between 42vf and 42v?

In this case the voltage is less than 16v.

The question of what the voltage of a 42V battery should be when it is de-energized should be analyzed based on the charge and discharge curve of the battery and of the nominal voltage. For a lithium batterym of 42V, the rated voltage should be 42V when charging, and the voltage should be less than 16V when the battery is fully discharged. According to different usage scenarios and usage frequency, the actual battery voltage data will be different.

It should be noted that when using or storing the battery, if you encounter abnormal conditions such as heating, expansion, leakage, etc. battery, you should stop using it or replace the battery in time to avoid safety hazards.

Tension force, objective.

1. Voltage Amperage: 42v means voltage amperage, while 42vf means 42 volts powered by lithium batteries.

2. Purpose: 42V voltage is commonly used in electronic equipment, while 42Vf voltage is commonly used in drive motors, such as DC motorsu and some drive motors.
