In the discharge diagram, the batteries are in two strings, and the connected batteries must meet the 20A discharge current, which can be achieved by connecting batteries in parallel or purchasing batteries with high discharge current. For example, if the battery is 2000mAH and the discharge multiple is 10C, then only 2 strings and 2 parallels are needed, and the maximum current can reach the discharge current 40A. For stable discharge, 2 strings and 4 parallels are required, and attention should be paid to heat dissipation. The discharged battery capacity will drop rapidly.
Battery charging diagram, 2 strings of batteries, fully charged 8.4V. The charging power supply voltage is DC8.4~9V, the charging current depends on the current value set by the charging power supply and the battery power, and the maximum is not more than 10A.
