I'm sorry but my ipv mini is right now bucking pretty accurately from 4.0V (battery voltage) down to 3.5V in DC-DC mode with a 0.7ohm atty.
It stays at 3.5 V with settings of 3.4, 3.3, .....on down.
I'm just saying.
I'm clueless
Me too.
Unless......there's a lower limit for output Current. Or draw current from the battery. Or a lower limit for the relationship between one of those amperages and available battery voltage.
This is why I have said from Day One that the ECF Needs on Dedicated Electronic Tech with a Scope to Test VV/VW devices when they come out.
LOL.
