yes that also is important to mention, thanks rum, these run lr and dual coil, who in the world would of thought that finally we have a ego sized batt that is well built and does what it was meant to, has passthrough ability, up to 6volts,even the volts scroll through when you hit either end.you can lock the unit and the volts, yes underload it drops a few points but nothing like past versions, all in all this does what it was meant to and works very very well. This is really what many have been wanting all along, a real variable that is light, small, sleek and does lr and dual coil and its priced incredibly.
