David:

	Very GOOD point! 
All this charger and control stuff has a very simple slide towword
Micros in everything. Since last week(when I realised I had time on my
hands..) I have had some interesting conversations with my partners and
supporting cast. Some see all this getting engineered into a few well
chosen set points that are set at the Factory. Some of us see giving the
user all the rope he needs to hang himself and do it with a smile. 
	Why not define a interface in Windows(or like) that lets you set up to
12 points(more/less?) that can be set to any volts, or amps for any
amount of time,and or Kwhrs, up to weeks. A simple point and click
charge profile.
	Stuff this into a EE rom on a PIC inside the charger. And hit go. Wanna
change things?? Ok No problem.
 
	My thing is yes this will happen, NO not right at this moment, becuse I
have to sell somthing to pay for the development of the next item. I
don't make a living and profit,and  I will be back to contracting.

Hey I gotta test stuff... so unless you want to toss wire strippers in
Kingston WA... I gotta get at it.
