To whom it concerns,
first time posting here so go easy

I recently bought the following kit from various sources;

30W solar panel, open circuit voltage; 20.8v
1 x Sunny Buddy
1 x Lipo Battery 5000mAh, 3.7v
1 raspberry pi zero, the load is 300mA max

I connected it all up, the Pizero powered up for a while but for the last two days it hasn't and the voltage across the battery when connected to the sunny buddy and when disconnected is approx. 1.7v.

Does the sunny buddy cut off current draw from the battery ( to the load ) when the battery voltage drops below a certain voltage to protect the battery?

Does anyone know what my problem might be here?

Thank you very much,

Paul

Also, I've tested the following:

from GND to Fault: 0.033v

from GND to CHG: 0.033v

According to the documentation this would constitute ON ON conditions which would read as "NTC Fault (Pause)"

But what does NTC mean?

Thanks,

Paul
