Quote ''Also, on that driver...do you have a way of measuring actual emitter current along with tailcap current? I'm curious to see if it delivers the 600ma/1cell and 1000ma/2cell outputs it claims."</p> <P>With the help of my son, sixty five thumbs and trusty DMM we arrived at the following list of numbers that may or may not make any sense. With different batteries the current reading will more than likely be different. Memory works without a hitch and the modes are well spaced. To sum up I'm happy with my first AA driver.</p> <P> </p> <TABLE border=1 cellSpacing=0 cellPadding=0> <TBODY> <TR> <TD vAlign=top width=154><SPAN style="FONT-FAMILY: Times New Roman; FONT-SIZE: medium"></span> <P align=center><STRONG><SPAN style="FONT-FAMILY: Calibri"><SPAN style="FONT-SIZE: medium">Mode</span></span></strong></p><SPAN style="FONT-FAMILY: Times New Roman; FONT-SIZE: medium"></span></td> <TD vAlign=top width=154><SPAN style="FONT-FAMILY: Times New Roman; FONT-SIZE: medium"></span> <P align=center><STRONG><SPAN style="FONT-FAMILY: Calibri"><SPAN style="FONT-SIZE: medium">Tail cap amps</span></span></strong></p><SPAN style="FONT-FAMILY: Times New Roman; FONT-SIZE: medium"></span></td> <TD vAlign=top width=154><SPAN style="FONT-FAMILY: Times New Roman; FONT-SIZE: medium"></span> <P align=center><STRONG><SPAN style="FONT-FAMILY: Calibri"><SPAN style="FONT-SIZE: medium">Led amps</span></span></strong></p><SPAN style="FONT-FAMILY: Times New Roman; FONT-SIZE: medium"></span></td> <TD vAlign=top width=154><SPAN style="FONT-FAMILY: Times New Roman; FONT-SIZE: medium"></span> <P align=center><STRONG><SPAN style="FONT-FAMILY: Calibri"><SPAN style="FONT-SIZE: medium">LED voltage</span></span></strong></p><SPAN style="FONT-FAMILY: Times New Roman; FONT-SIZE: medium"></span></td></tr> <TR> <TD vAlign=top width=616 colSpan=4><SPAN style="FONT-FAMILY: Times New Roman; FONT-SIZE: medium"></span> <P align=center><STRONG><SPAN style="FONT-FAMILY: Calibri"><SPAN style="FONT-SIZE: medium">Single Turnigy AA 2200 mAh LSD battery.

I have not taken any measurements with this battery at the LED. Just a couple of pictures comparing high with a AA NiMH Turnigy and a 14500 Lifepo4.</p> <P>Firstly the NiMH measuring at the time 2.45 amps at the tailcap.</p> <P><IMG src=" HTML http://i1074.photobucket.com/albums/w415/mrsdnf/Red%20AA%20host%20XP-G2/245ampNiMH_zps0e7dce9d.jpg"<br />/></p> <P> </p> <P>And secondly the Lifepo4 battery at .9 amps at the tailcap.</p> <P><IMG src=" HTML http://i1074.photobucket.com/albums/w415/mrsdnf/Red%20AA%20host%20XP-G2/09ampLifepo4_zps2111a2d8.jpg"<br />width=1024 height=768 /></p> <P>Mouse over anyone please.
