Power amplifier board voltage is high, the LED indicator burned, the test voltage of 17V, with a multimeter test voltage regulator diode voltage 17 ~ 23V, can not find the reason, I hope someone can help answer.
I would really like to get OTA working here as it's freezing outside and I have to go there to update the software in the greenhouse control system.
So please, can we have a 'how to' step-by-step guide to OTA? Please?

I will go with a Li-Po Battery type: 304048 3.7V 1200mAh
Might work, but maybe the internal protection will trigger with the high current peaks. I'd suggest you plan a 0 Ohm, (2512/THT) resistor as R2 and then replace it with a 100Ohm/1Watt if the protection triggers.
