Matching a Speed Controller to a Lithium Battery
For example, if the controller has a low Voltage cut off level of 31 Volts and the lithium battery has a discharging cut off Voltage level of 25 Volts then the controller will shut down before the battery pack has been used to its full discharge capacity, resulting in a lower amount of ride time or mileage range than the battery is capable of.

BATTERY PERCENTAGES NOT MATCHING | Page 2 | Ford
It is very difficult to balance the cells/modules below true 90% SOC due to the very low voltage difference below that. Ford protects the top 7-8% SOC so we need to be at 100% gauge SOC for the balancing to work effectively. The top balance is needed for all Lithium battery chemistries occasionally.

View more6 FAQs about [Low voltage battery matching]
What level of cell matching do you do before assembling a battery pack?
What level of cell matching do you do prior to assembling a battery pack? Assuming the battery pack will be balanced the first time it is charged and in use. Also, assuming the cells are assembled in series. Cell balancing is all about the dissipation or movement of energy between cells, so the SoC of all are aligned.
What is the difference between high-quality and low-quality batteries?
High-quality cells continue to perform longer than the lower-quality counterparts, and fading is more even and controlled. Lower-grade cells, on the other hand, diverge more quickly with use and time, and failures due to cell mismatch are more widespread. Cell mismatch is a common cause of failure in industrial batteries.
What makes a good battery pack?
Battery packs with well-matched cells perform better than those in which the cell or group of cells differ in serial connection. Quality Li-ion cells have uniform capacity and low self-discharge when new. Adding cell balancing is beneficial especially as the pack ages and the performance of each cell decreases at its own pace.
Do nickel based batteries match each other?
Cell matching according to capacity is important, especially for industrial batteries, and no perfect match is possible. If slightly off, nickel-based cells adapt to each other after a few charge/discharge cycles similar to the players on a winning sports team.
Do EV batteries need cell balancing?
For cost reasons, EV batteries use mainly passive balancing. Single-cell applications in mobile phones and tablets do not need cell balancing. The capacity between cells can vary and each cell is allowed to age on its own terms without causing harm, other than delivering shorter runtimes.
When should a battery pack be balanced?
Assuming the battery pack will be balanced the first time it is charged and in use. Also, assuming the cells are assembled in series. If the cells are very different in State of Charge (SoC) when assembled the Battery Management System (BMS) will have to gross balance the cells on the first charge.
