Example: Bus battery

7x 100Ah NCM29.4VWeight 16.1kg

8x 100Ah LFP29.2VWeight 25.6kg

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
