IOS Boost 1/2*AA, CR123A Circuit board review

[html]<P>I have used this driver (<A

href="

/>asked a question that I was dreading. 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

</p> <P>Just a quick update for this driver with Lifepo4
batteries. 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

.9 amps at the tailcap.</p> <P><IMG

Thanks spas. This is one off the best drivers I have tested
running AA batteries but unfortunately it is no longer in stock
at IOS.
