{"title":"DC-DC Charge Discharge Integrated Module (5V/2A)","handle":"dc-dc-charge-discharge-integrated-module-5v-2a","url":"/products/dc-dc-charge-discharge-integrated-module-5v-2a","description":"This is a DC charging and discharging integrated module, with 5V normally open output, which is not affected by load access and has a maximum load current of 2A. It features 4 levels of charge/discharge electricity indication and button-controlled output. The module comes with a built-in power management circuit that boosts a lithium battery to 5V and supports charging and discharging simultaneously. Besides, it has battery protection which makes it applicable for batteries without a protective board, This module can be applied to car charging retrofit, driving recorder power supply, DIY mobile power bank, and mobile phone/laptop portable charging devices. Note: The KEY function is invalid in charging mode. In discharging mode, short press the button once to enable output, and the indicator turns on; Long press for about 10s to disable the output, and the indicator turns off this time. The indicator goes off after 35s when there is no operation in discharging mode. When charging and discharging at the same time, please enable input and output to keep a balance, thus extending module service life.
