In this video, I am using my just completed and calibrated Powermon to investigate an Ansmann Energy8+ charger. This charger is quite notorious about refusing to charge batteries for apparently no good reason, so it makes a perfect test object for trying out my new Powermon.<br /><br />In the end I managed to get some understanding of what the charger does and why but of course there is still some more to explore in the future. The investigation also uncovered two bugs in the Powermon software, so all in all not a bad result.<br /><br />The revised Powermon software (rev 4.2) is on my Github pages below. <br /><br /><a href="https://github.com/TheHWcave/PowerMon" target="_blank" rel="nofollow">https://github.com/TheHWcave/PowerMon</a><br /><br />If you are new to Powermon you may want to check out the 4 videos about it.
