Lead acid cut off voltage is 10.5 volt, for 3 s li ion it is 9 v, at 10.5v you can't use half of your battery capacity

Is there any issue with the way the UPS charges the battery, since we're going from a lead-acid battery to a lithium-ion battery? Or does the BMS board handle all this?

Стоит 3 бакса в Китае такой коробок с держателем на 21 аккум 18650. Лента готовая и БМС на 40 ампер в комплекте. 3$. Размер как 12в.7 ачас.
