6 FAQs about [Reason why there is no voltage at the output end of the battery pack]
What happens if a battery has a low voltage?
Voltage differences between cells can lead to decreased overall performance of the battery pack. During discharge, cells with lower voltage will limit the overall discharge voltage and capacity of the pack, reducing the total energy output. Voltage inconsistency can cause imbalance during charging and discharging.
What if there is no current flowing out of a battery?

What if there is a gap in a battery pack?
If there is a gap in the voltage of the battery pack, you can correct it with additional equipment, such as with a BMS, balance charging, etc. Stay tuned for Part 2 of voltage difference: How to prevent voltage difference. This is all that we’re covering today.
What if there is a voltage difference in a battery pack?
Therefore, you should pay attention to the brand from which you are purchasing your batteries. If there is a gap in the voltage of the battery pack, you can correct it with additional equipment, such as with a BMS, balance charging, etc. Stay tuned for Part 2 of voltage difference: How to prevent voltage difference.
How does voltage difference affect battery performance?
For battery packs, the voltage difference between individual cells is one of the main indicators of consistency. The smaller the voltage difference, the better the consistency of the cells and the better the discharge performance of the battery pack.
What happens when a battery is discharged?
During Discharge: As a battery discharges, its voltage gradually decreases. For example, a lithium-ion battery will drop from around 4.2V (fully charged) down to 3.7V, then further to 3.0V (cut-off voltage), after which the device will stop working. During Charging: When charging, the battery voltage increases.
