Ahoy and good morning all!
Yeah, exactly the problem, too much voltage drop at high amps. A circuit that drops only a small voltage can't handle the high current people are using lately, and a circuit that can handle the high current drops way too much voltage so the dna would quickly think the battery was depleted when it was not.
Thanks for the data, it confirms what I've found so far.

Well, back to work on the batch again today, happy Wednesday! arrr
If I am reading this correctly the FET is causing bairly any voltage drop .01-.02 two one hundredths of a volt is hardly enough to not use it. Here is her quote from just a couple posts later
"I did and voltage drop is essentially the same (the same or 0.01 - 0.02 volt difference) with the FET vs without. So this is definitely great news as it means the FET isn't affecting load and is only providing reverse polarity protection.
It also means the AW 18650 batt doesn't hold up well under load with the DNA20D running at higher watts. At least using a mod with the DNA20D and a single 18650 batt. A voltage drop >.4 @ 15W is significant. Dual 18650 batts in parallel, of course with the doubled max discharge, hold up well under load at higher watts.
I now have it in my Denali DNA20D mod that has dual 18650 batts and also my Sam mod with a single 26700 MOLI batt. Both are working great with this FET! I am so in my comfort zone now with having reverse polarity protection for these mods."
