Our two years be returned to our warehouse, will be inspected and tested by our 20.27inch 13.22inch 11inch P + P - ON/OFF VENT Monitor BLUE TOOTH 05 Charging Tips Based on the characteristics of Lithium Phosphate (LiFePO4) batteries, all LiFePO4 batteries have violent internal chemical reactions during the charging process, the lithium ions are very active, and the battery voltage is relatively high. After charging and disconnecting the battery from the power source, the chemical reactions inside the battery slow down and the battery's voltage gradually decreases and stabilizes. If you need to test the accurate and stable voltage of the battery, please test its voltage after leaving the battery for more than 120 minutes after disconnecting the power supply. 06 Appearance introduction 1 P+: Battery pack output / Load positive terminal interface; Char- ger positive terminal interface. 2 Power Switch: Turns output ON/OFF. Press once to enable output; press again to disable output. 3 Bluetooth Signal: Bluetooth signal transmission and reception. 4 Display Interface: External display mounting port.
