2 Charge the battery below 10AH with the minimum current. Minimum starting voltage > 2.0 V Power and load :MAX; 280W Size :158 x90x50mm(6.22 * 3.54 * 1.97 inches) .Net weight: 470g Note :1 Only charge the lithium battery with battery protection board(BMS). can have more capacity, the larger the capacity needs longer charging time. Output current :12V20A & 24V10A Support ah: 2AH-300AH... LifePO4:14.6V / 29.2V. Lead acid :14.7V / 29.4V. Max: Lithium :12.4V-14.6V / 24.8V-29.2V. Lithium /LiFePO4/ lead acid (AGM,GEL,EFB, MF, Flooded, VRLA, SLA and wet battery..). (normal - Max:13.2V-14.6V / 26.5V-29.2V). Output voltage :12V / 24V. P20 parameters AC input :100v-240v~ 50/60 hz. 3: Fan noise? It is normal that the fan has wind. Added a small current after full charge uninterrupted charging. (3 gears can adjust charging current, large current, fast charging) 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-2V, which is normal. 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. 20-amp Smart Battery Charger P20 amp smart battery charger Problem 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
