Matt, so how do the golf cart batteries recharge? If from the  car
alternator/generator, you still only have a source of 30 to 37 amps  
=========================================================
 
 charge??  just like a Motor Home!!  millions of units out  there working 
fine!
 
1  A battery isolator [ diode!]
 
  2 - 6 volts in series = 12 volts...  Heater  wired to THEM!!   not the car  
[ think coach batteries!]   Coach goes dead.. but RV's engine still cranks 
and starts!
 
 
2  KEY  is RESERVE CAPACITY!
 
 
 We have no idea how long the heater will run each drive...   what 
conditions, etc...
 
 IF  he were to run out on the way to  work... then 4  Batteries!  [ very 
unlikely! ]
 
 
 To charge a 200 amp hour system...  from fully discharged.. at  30 amps 
would take approx. 10 hours!! [  nothing is 100%  efficent!  ]
 
 BUT  the batteries will start out fully charged...
 
 draw may be 30 amps....   but cars alternator, running  everything else is 
only sending 15 amps to GC  batteries....
 
That's only a 15 amp  draw!   / 200  AH     13 Hours!! before batteries run 
down!!
 
AND a 60 amp Alt.  is super cheap and a bolt on!
