AI Customer ServiceConverting battery-operated devices to AC power can be a useful and cost-effective solution to keep your devices running without the need for constant battery
AI Customer ServiceDon’t allow the battery voltage to drop below 3.0V as it can damage the battery Lithium batteries will often have a specified maximum discharge current of say 2C, which means 2x their mAh rating. For example a 120mAh battery with a 2C max discharge current would only allow you to draw up to 240mA continuous operating current.
C/10 and C/30 are common charge termination current limits. When the battery is fully charged, the battery should be disconnected from the charger. Leaving the battery connected to the charger will cause the battery to overcharge and will damage the battery. The 18650 is popular cylindrical lithium cell, with a capacity of 2500 mAh.
This means that the charge current should be half the battery capacity. For a 2500 mAh cell, the standard charge current would be 1250 mA. The battery cell will have most of its charge when the battery voltage reaches 4.1 V or 4.2 V. At this point, the current going into the battery gradually decreases.
Another easy way to charge a lithium battery is to use Linear Technology’s LT3650, a DC-DC converter with integrated lithium-ion battery charger intelligence. A designer adds a few passive components to implement a complete lithium battery charging solution.
During the constant current charge, the lithium cell is discharged. The cell will sink as much current as it is given, although providing too much current may be dangerous. Stay at or below the limit specified by the datasheet. A standard charge on a datasheet is typically defined as 0.5 C, where C stands for capacity.
Under no conditions you should connect unregulated 5V to LiIon - current will be >10A and something would explode (PSU or battery). You need regulated current circuit. It sounds like what you're building is a dock that will accept multiple phones and power them all at the same time.
