Lithium-ion cells don''t have a steady voltage profile. An LFP cell discharges from 3.60V – 3.65V (depends on the cell brand) to close to 3.2V and offers a flat voltage curve during discharge, and then goes all the way down to 2.5V. On the other hand, an NMC cell discharges from 4.20V – 4.25V (depends on the cell brand) and has a

NMC cells are more energy dense than LFP cells, so if you need a smaller battery NMC is the battery type for you. LFP chemistry, however, is much more safe than NMC lithium-ion chemistry and LFP cells are far less likely to overheat. So, if safety is your biggest concern, LFP may be the better option. Also, the voltage curve of LFP cells

The cell voltage of lithium ion batteries with NMC cathodes is 3.6–3.7 V. Arumugam Manthiram has reported that the relative positioning of the metals'' 3d bands to the oxygen 2p band leads to each metal''s role within NMC cathode materials. The manganese 3d band is above the oxygen 2p band, resulting in manganese''s high chemical stability. The cobalt and nickel 3d bands overlap the oxygen 2p band, allowing them to charge to their 4+ oxidation
