USB Rechargeable Battery S50

Additional information

Capacity	12V33AH-250AH

The original design is that the USB fast-charge lithium battery will reduce the 3.7V lithium battery to a constant voltage of 1.5V through the chip so that the electrical equipment can continue to maintain a strong power output, but it will also cause a series of defects to the electrical equipment such as severe fever, short use time, etc., and there is no low battery reminder function.
Allsda changed the USB fast-charge lithium battery from the original 1.5v constant voltage solution to a 1.5v-1.0v step-down solution to simulate a battery discharge solution. While ensuring strong power output, it also changed the severe fever and short use time caused by the 1.5v constant voltage, increase the low battery reminder function at the same time.
