Re: (ET) chargers - 8V

[Klein Robert W NPRI <KleinRW Npt NUWC Navy Mil>]

OR..... Try and find a miolitary surplus battery charger like the kind 
Fair Radio sold a while ago.  Mine is completely variable from 1 to 154 
volts.

           Here's a "Try At Your Own Risk" idea. Install a larger value 
capacitor in a  GE charger. It of course will result in outside of 
intended range operation, but with some careful monitoring and a bit of 
trial and error you just might pull it off.You just might find a Lister 
that has replaced the GE charger with a late 20th Century upgrade. A 
donation to science and the greater good and all that. :)

        Hi All,
         
        I have a bunch of 8V Trojans that I am planning to use for my EV.  
I recalled that some of you have souped up your ETs with those batteries 
instead of the 6V ones, to make the pack a 48V pack.
         
        The ones I have are old, and were bought at scrap value mainly, to 
use as mockups for the battery packs.  However, they will hold a charge 
and can be used for initial power up testing before buying a brand new 
pack.
         
        However, i can't seem to be able to find a 8V charger that can 
equalize the charge in each battery individually, and would rather do that 
than charge three at a time at 24V or six at 48V.
         
        Any recommendations for large lead-acid 8V chargers, and sources 
where i can purchase one?
         
        Cheers
         
        Matt
