(ET) Charging with multiple 12V chargers

[Ken Olum <kdo cosmos phy tufts edu>]

More than a year after I first wrote about charging with individual 12V
chargers, I have a working system.  I wrote all about it at
http://cosmos.phy.tufts.edu/~kdo/12V-chargers.html .

In brief, I'm now charging my Electric Ox with 4 CTEK Multi-US 25000
chargers.  These are great units, though rather expensive.  Before I got
to this point, I tried multi-bank chargers from Minn Kota and Dual Pro,
with many problems.  Current Minn Kota and Dual Pro chargers are not
compensated for battery temperature, in spite of what their
manufacturers said when I bought them.
