Does this board have built in undervoltage protection? The datasheet mentions nothing about it but the board has a strict 4.8v to 6.5v solar input terminal.
I am using a 10W solar panel and regulating it with a 10W regulator dropping the 9.43V down to 6.17V which is in the acceptable range of the lipo rider pro. The problem is that if the solar panel is shaded even temporarily, the voltage drops down to 5v, 4v, 3v, 2v, and then effectively cuts off.
I am just worried that this provided low voltage would damage the lipo rider pro and wondering if it has built in protection against this.
If it doesn’t have any undervoltage protection, I would really appreciate some links/tools/resources for developing an undervoltage protection circuit. This project uses an arduino mega and numerous 5v sensors just to give an idea of the kind of circuit.
