I have a few diodes 1N4001 and 1N4148. Would any of these work?You can also use the 5V pin as a voltage input but you must have some sort of diode (schottky, signal, power, really anything) between your external power source and this pin with anode to battery, cathode to 5V pin. There are two pads on the back, with the protection diode in series, so you could use those if you wish.
Alternatively, if I wanted to use the BAT/GND pads, is there a way to connect to them that doesn’t involve soldering? I don’t want to solder them just for a test. If all goes well I will be using a BFF LiPo charger in my final project.
