I got some motion detecting under cabinet LED light bars at a low price. The tiny li-po batteries go with the tiny price. Set the switch to auto and the power they use monitoring the sensor has them working for about a day before needing recharged.
Looks like an easy solder job to swap in some much higher capacity ones. No markings at all on the battery.
The larger chip with 8 pins has no markings. The tiny 6 pin chip at the USB end is a LTH7. Constant current/voltage charger for single cell li-po. Other components are just diodes, capacitors, resistors, and one J3Y transistor in the motion sensor circuit.
The li-po cell appears to not have its own protection for over/under charge.
Would using a larger li-po cell with its own protection work as a direct swap?
