LiFePO4 questions
Short answers to the ones that come up most.
What makes LiFePO4 different?
Lower energy density than NMC, far better thermal stability and cycle life.
How long does a pack last?
4,000–6,000 cycles at 80% DOD.
Can it be charged in the cold?
Not below 0°C without a heater.
Does it need maintenance?
No watering, no equalising — terminals, ventilation, BMS log.
Is it safe?
The safest lithium chemistry in wide use.
