Hello - I'm new here! Look forward to joining in with the community. Here's to a better 2021.
I've recently built an arduino project of my own design. It charges and discharges batteries and give Ah and works out internal resistance.
I used a high side switching arduino MOSFET switch to connect and disconnect the battery / load. It all seemed to work well.
However (there's always a but!) If I connect a 1.5V battery, the MOSFET fails to switch on / conduct properly.
I only have limited technical knowledge of MOSFETs, but even with 5V PWM applied to the gate, should the FET be able to conduct low voltages below 1.5VDC?
any pro (or non pro) advice would be food for thought. Kind regards
Dan
