20 amp smart battery chargerProblem 1: Can't reach the maximum charging current? To protect the battery, the system automatically identifies the battery voltage and selects the most appropriate current to charge the battery. When the battery voltage is low (for example, the 12V battery voltage is less than 11V), the system automatically charges the battery at the maximum current. (3 gears can adjust charging current, large current, fast charging)Problem 2: The LifePO4 battery is not fully charged? When the battery is fully charged, it has a callback function, reducing the charge by about 1V, which is normal. Added a small current after full charge uninterrupted charging. 3: It is normal that the fan has wind.P20 parameters: ac input :100v / 240v~ 50/60 hzOutput voltage :12V / 24V.
