Tuya temperature sensor battery upgrade

I created battery upgrade for Tuya temperature&humidity sensor, because original AAA bateries dies in couple monts.I soldered wires directly to the electronic, because that was easier for me, but you can also find dummy AAA bateries to put in.Battery 18650 is wired directly to sensor (sensor already have 3,3V regulator).18650 TP4056 Lithium Battery Charger Module.There are many things that I will change if I ever create V2, but for now this is perfect.
