Not finding any with my fancy new meter
But I feel it
Tested with the very same full charge AW IMR and very same Cisco 1.5Ω atty
Battery with meter 4.20 volts
Grand with no load 4.20
Woodvil with no load 4.19
Grand under load 3.84
Woodvil under load 3.88
I was expecting to see a .2 or .3 difference judging by what I feel in the throat.
(Im good, but I don't think I am "feeling" a .04 volt difference)
Meter from COV with a 510/510 extension on it. Pretty cool little piece for 15 bucks.
Seems really well made and durable ... Time will tell though.
