Same energy inside, but NCM is half the size only and 40% lighter!



NCM voltage dropping almost in a

straight line from top to the knee easier detection of SOC

LFP voltage almost constant between

95 and 20% SOC difficult detection of SOC



NCM allows to take out more energy at low temperatures than LFP
