The battery''s BMS should detect when the battery voltage falls to around 10 volts and trigger low-voltage cutoff. (Low-voltage cutoff is also called low-voltage disconnect, which you''ll sometimes see abbreviated LVD.) Note: Some batteries have higher cutoff voltages, such as 10.6V. So the limit in your battery manual may not be exactly 10V ...

Generally, the negative electrode of a conventional lithium-ion cell is graphite made from carbon. The positive electrode is typically a metal oxide or phosphate. The electrolyte is a lithium salt in an organic solvent. The negative electrode (which is the anode when the cell is discharging) and the positive electrode (which is the cathode when discharging) are prevented from shorting by a separator. The el…

However, one battery cell is not always enough to power a practical load. Instead, battery cells are connected in series and parallel, into a so-called battery pack, to achieve the desired voltage and energy capacity. An electric car for example requires 400-800 V while one single battery cell typically supplies 3-4 V.
The phosphate-based lithium-ion has a nominal cell voltage of 3.20V and 3.30V; lithium-titanate is 2.40V. This voltage difference makes these chemistries incompatible with regular Li-ion in terms of cell count and charging algorithm.
For different applications, it might be necessary to have different designs for high-energy cells and long cycle cells. For example, lithium iron phosphate (LFP) batteries are more stable and have a longer cycle life than other transition metal oxide-based batteries (Fig. 10 a) [43]. It has been demonstrated that LFP batteries can achieve more ...
