Our PPC Series comes with the AC/DC Smart Charger built-in to properly charge and fully maintain the battery voltage whilst providing clean 12Vdc power for all sensitive electrical equipment, with or without a battery in line. User adjustable DC voltage is standard so the PPC Series can be used with many battery types, including Lithium on our single Fixed output mode so no need to change when upgrading the battery type in the future. | PowerMax Power Center - 65A
