18650 UPS

My version is modified to use with batteries soldered to the board, as I intend to use it as a power source for nighttime lighting on my bike and it also contains the following modifications:

1 - I cut the connection from pin 5 (enable) to pins 3/4 on the board, to be connected with a two-position switch, with the central connection connected to pin 5 and the side pins gnd and pins 4/3, the motivation is to reduce the standby current.

2 - I removed resistor R8 responsible for the LED, to save battery.

3 - I removed the battery holder to save space

-- 4 screws m2.5x14 or longer are required.

***** Small spacers are printed attached to the corners to help hold the edges together, and once printed they can be removed and stored for future use.
***** DOES NOT WORK WITH THE BATTERY CASE



Minha versão é modificada para usar com as baterias soldadas na placa, pois pretendo usar como fonte de energia para iluminação noturna na minha bicicleta e também contem as seguintes modificações,
