The "nominal" voltage is the average voltage across the entire useage cycle. If you charge a pack to 4.10V per cell (in series), then a 6S pack would be 6 X 4.10 = 24.6V. If you set the Low Voltage Cutoff (LVC) at 3.3V, then the battery will cut out after running the E-bike for a while, and the 6S voltage is down to 6 X 3.30V = 19.3V

Due to the higher density in lithium-ion battery packs, there is an increased risk of catching fire. So as mentioned earlier, it is essential to operate batteries at rated value. A BMS does this work for you. It avoids over-charging and over-discharging of the battery
This can prevent the battery pack from overcharging, over-discharging, or overheating, which can cause fires or lead to permanent damage. Longer lifespan: The BMS boards can balance the cells of a battery pack by ensuring that they all receive an even charge and discharge. This feature can effectively prolong the battery pack''s lifespan.

A Battery Management System (BMS) is an intelligent electronic system that monitors and controls the operation of a battery pack, which can be called the "brain" of the battery. The BMS is responsible for ensuring the safety, efficiency, and longevity of the battery by managing crucial factors like voltage, current, and temperature.
Battery balancing equalizes the state of charge (SOC) across all cells in a multi-cell battery pack. This technique maximizes the battery pack''s overall capacity and lifespan while ensuring safe operation. Due to manufacturing variations, temperature differences, and usage patterns, individual cells can develop slight differences in capacity ...

It does this by monitoring the voltage of each cell in the pack and then balancing the cells so that they all have the same voltage.
Does Higher Battery mAh Mean Longer Life? When it comes to batteries, the term "mAh" stands for milliampere-hours. It is a unit of measurement that represents the amount of energy a battery can store. The higher the mAh rating, the more energy the battery can hold.
A LiPo cell has a nominal voltage of 3.7V. For the 7.4V battery above, that means that there are two cells in series (which means the voltage gets added together). This is sometimes why you will hear people talk about a "2S" battery pack - it means that there are 2 cells in Series. So a two-cell (2S) pack is 7.4V, a three-cell (3S) pack is 11 ...
Does a higher Ah battery mean more power? In short, not necessarily. Even though the Amp=-hours doesn''t automatically mean the battery is more powerful by the numbers, sometimes it can equate to more power. In a higher Ah battery, the number and density of cells supplying the current and the heavier gauge of the conductors and components ...
