Both are lithium-ion batteries; the difference is the cathode. NMC (nickel manganese cobalt) holds more energy per kilo, so it helps range and weight, and it is the chemistry in most electric cars above about Rs 40 lakh. It ages faster at a high charge or in heat, so the usual advice is to keep it between about 20% and 80% day to day. LFP (lithium iron phosphate) holds less energy per kilo but lasts about twice as many charges, copes better with heat and costs less per kWh, and it can usually be charged to 100%. Most electric cars under Rs 40 lakh use it. Your car's manual comes first.
