Re: (ET) panels - materials besides steel ?

One way to be pretty much done with battery box corrosion is to fit VRR 
(valve regulated recombinant) batteries.  "Maintenance free" 6 volt golf 
car 
batteries are made in gel and AGM versions.  

The downsides are, regrettably, significant.  They're appreciably more 
expensive; they have a bit less range per charge; and they're not as 
tolerant of careless charging.  The last is a big one - you'd need a new 
charger that understands the needs of your particular chemistry.  That old 
GE blunderbuss would trash a set of gel batteries in no time at all.  

Also, you'd be on shaky ground tapping the pack for the lights and lift.  
That imbalances the pack and VRR batteries can't really handle much of the 
brute force equalization that the GE charger performs to deal with the 
imbalance.  Might have to add a DC:DC converter (or even two).  Or you 
could 
charge the way I do - charge each battery individually, or at least in 12 
volt pairs with the lift on a 12v or 24v tap.
