FAQ

Q1: What charging options does this 21Ah LFP cell support?

A: It supports conventional slow charging and temperature segmented step fast charging, and fast-charging current will change according to ambient temperature.

Q2: Is continuous charging available below 0℃?

A: Discharge can work down to -30℃, but continuous charging below 0℃ is strictly prohibited to protect cell lifespan.

Q3: How much capacity remains under extreme low temperature of -30℃?

A: Under -30℃ environment with 1C discharge, the cell can keep more than 55% of its nominal rated capacity.

Q4: What is the normal cycle life of this lithium cell?

A: It reaches 2000 cycles at 25℃ and 1000 cycles at 45℃ with 80% remaining capacity; calendar service life can reach 8 years under standard storage condition.

Q5: What is the proper SOC for long-term storage?

A: Long-term storage needs to keep SOC between 30%~50%, and regular full charge-discharge once every 3 months.

Q6: Can these cells pass strict safety destructive tests?

A: Yes, all cells finish overcharge, short circuit, needle prick, extrusion, high temperature heating and other safety tests without fire or explosion.

Q7: Do you accept customized PACK solution for these cells?

A: We provide OEM & ODM customized pack design service according to customers’ actual voltage and capacity demands.

Q8: What’s the maximum allowed working temperature during discharge?

A: The highest allowed core temperature is 60℃ when discharging, stop using once over the limit value.
