Questions and Answers:
Q1: Can the LifePO4 battery be fully charged?
A1: When the battery is fully charged, it features a back-up function, reducing the charging voltage by about 1 V, which is normal. Continuous charging at low current after full charge.

Q2: Is there a problem if the fan makes noise?
A2: Please don't worry. It's normal that the fan of the charger makes a little noise.
