Temp compensated chargers are readily available in the green energy
field and don't cost $400 either:

(fine, only 35A...)
There are lots of other models available too.

tabe,

Believe that random link is to a Charge Controller made for PV  (solar
panel) systems.
Nice looking unit at a reasonable cost.

If this Controller were hooked-up to a stock Vanagon Alternator output,
the results
would be disappointing. Zap, then smoke I assert.... 8>(
Stock Alternators have a bad habit of outputting voltage spikes in the
range of a 100 or so volts.
Not continuously but enough to smoke an unprotected charge controller.

DC to DC Chargers are available. Shoot a p-mail to Mr Squirrel for the
details....

regards

Phil Z.
