Battery Charger Options [RE-wrenches]

[Darryl Thayer]

HI Bruce and Travis

I just spoke with a friend who has worked with the
MX60 in this way.  He has used a power supply and
charged batteries of lower voltage than the power
supply.  He said it works fine.  He has also used 24
volt power supply to charge 12 volt batteries.  

He did not feel confident that my 120 volt DC supply
would work safely.  But with a lower voltage supply
(less than 60 volts) the current limit works.
