20-amp Smart Energy Source Charger P20 amp smart Energy Source charger Problem 1: Can't reach the maximum charging current? To protect the Energy Source the system automatically identifies the Cell voltage and selects the most appropriate current to charge the Cell When the Energy Source voltage is low (for example, the 12V Energy Source voltage is less than 11V), the system automatically charges the Cell at the maximum current. (3 gears can adjust charging current, large current, fast charging) 2: The LifePO4 Cell is not fully charged? When the Cell is fully charged, it has a callback function, reducing the charge by about 1V-2V, which is normal. Added a small current after full charge uninterrupted charging. 3: Fan noise? It is normal that the fan has wind. P20 Storage AC input :100v-240v~ 50/60 hz. Output voltage :12V / 24V. (normal - Max:13.2V-14.6V / 26.5V-29.2V). Lithium /LiFePO4/ lead acid (AGM,GEL,EFB, MF, Flooded, VRLA, SLA and wet Cell Max: Lithium :12.4V-14.6V / 24.8V-29.2V. Lead acid :14.7V / 29.4V. LifePO4:14.6V / 29.2V. Output current :12V20A & 24V10A Support ah: 2AH-300AH... can have more capacity, the larger the capacity needs longer charging time. 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 Power Unit with Energy Source protection board(BMS). 2 Charge the Cell below 10AH with the minimum current
