Frequently asked questions
Can this charger charge two 18650 cells at once?
No. The 4.2 V output is designed for one Li-ion cell. Charging a series pack needs a charger with a higher output voltage that matches the pack.
Can I charge LiFePO4 or NiMH cells with it?
No. This charger is specified for 4.2 V Li-ion cells. LiFePO4 and NiMH cells require a charger with their own voltage and charging profile.
