(ET) battery charger controller

To the list:

Well, it seems like there might be some interest. If there is anyone who is 
local enough to come by with some goodies to swap, they can have the 
controller and/or the charger. And I can show them some of the other 
accessories I have made as well. If not, I can ship it.  Then maybe they can 
report to the list how it worked out. I'm thinking that $50 would be about 
the price for a controller and solid state relay. But that's just a 
guesstimate right now. It would take a few serious orders to make it worth 
laying out a board and having some made.
I like 38V because that is about the voltage that a fully charged 36V pack 
will settle to with no load. That's 2.11 V/cell. Plenty of people have 
recommended higher, but I like 38V. The circuit has a pot on it to set the 
voltage anywhere you like.
