Battery chemistry comparison: NMC vs NCA vs LFP

Parameter	NMC (Lithium NMC)	NCA (older Tesla)	LFP (BYD, MG, Tesla MIC)
Nominal cell voltage	3.7V	3.6V	3.2V
Max charging voltage	4.2V	4.2V	3.65V
Energy density (Wh/kg)	200-250	250-300	140-180
Charge cycles (to 80%)	1500-3000	1500-2500	3000-6000
Thermal safety	⚠️ medium (250°C breakdown)	⚠️ medium (200°C)	✅ high (270°C)
Low temp performance	OK to -20°C	OK to -20°C	⚠️ poor below 0°C
Price per kWh	$$$ higher	$$$ highest	$ lower
Best for DIY	✅ compromise	⚠️ only old Tesla	✅✅ ideal for home

DIY conclusion:

LFP (BYD, MG, Tesla MIC): safest, longest lifespan, ideal for home storage (where temperature is always >5°C)
NMC (BMW, VW, Renault, Hyundai): most popular, good compromise, plenty of available batteries
NCA (older Tesla S/X): highest energy density but higher thermal risk and shorter lifespan
