Re: (ET) Vacuum running, man does it draw power.

Yep. The bag works in the trailer with the front panel of the trailer removed. It does cut pressure, but on the other hand it sucks up dirt, leaves, trees, everything and doesn't blow the wreckage everywhere. It will do for this season, but I do want to see your get-up.
Emptying the bag releases a massive amount of highly ground up leaves. Much finer mulch than the Craftsman. Now I'd like to find 20 feet of cheaper hose and use the vacuum to clear leaves out of beds and such....

Chris, are you still heavily restricting the output air flow?  Maybe that would explain your crazy current draw.  I run the noggler for a couple of hours with a stock lead acid battery pack, but I have a 5'x3' panel of 1/4" steel hardware cloth letting the air out of the top of the leaf collection cart. 

Apologies for not sending the pictures yet!

    I have an elec-trak vacuum blower I bought new from Bill Gunn years
    ago.  Mine does not draw a lot of amps, perhaps 15-22 amps.  I can
    check the actual amount next weekend if you would like.  Reduces my
    range a  notably but nothing dramatic.

       If you're running a 90ah battery flat in 30 mins, your load is
    180 amps!
       That's HUGE.  Lead batteries do NOT like that kind of load.

    A similar problem with snow blowing is why I have AGM batteries in my
    Ox.  But there are some other issues.  Is an Elec-Trak wired with AWG 6
    wire?  I don't remember.  AWG 6 is rated for 75A (with 90C insulation
    and 20C ambient).  And isn't there a 90A circuit breaker?  Leaf
    vacuuming is much more of a continuous activity than snowblowing and 
you
    do it at higher outside temperatures, so overheating seems like an
    issue.
