Well, as far as I could tell by the Volt meter, the pack wasn't sagging below 90V. Is that measured at the battery terminals or at the input to the Zilla? Voltage might be really sagging through the cabling or a high resistance connection. -- next part -- An HTML attachment was scrubbed...

Re: [EVDL] Slow due to 96V pack?
I seem to recall that the minimum input voltage for a Zilla is 72 volts. Might be sagging the pack to 72 volts and that is that is simply amps it puts out at that voltage.

Re: [EVDL] Slow due to 96V pack?
John, As someone mentioned, even at 120v you won't get great acceleration with GC batts. That's why we often call them "lead sleds".

Re: [EVDL] Slow due to 96V pack?
When I was driving my S-10 with 20 6v golf cart batteries (120v pack) I was never able to draw more than 240-300 amps from the battery pack even when the batteries were new. (and the acceleration wasn't great in anything but 1st gear from 0-20mph...) If your friend's pack is used, 200 amps seems reasonable, especially for a 96v pack, which will probably have even more of a voltage sag than my 120 volt pack. I definitely recommend upgrading to LiIon (perhaps from a wrecked Leaf pack, which is what I did...)

You need to set all four to the appropriate values. You never said if you were reading battery current or motor current. Makes a bit of difference. Also, it would be useful to know the battery voltage under load. Bill D. On 9/8/2017 9:51 PM, John Lussmyer via EV wrote: I'm helping a guy with a used conversion he just bought.

I was never able to get it to draw more than 200 Amps in any gear at any speed. (Zilla limit is set to 500) About 18KW max. Is this likely to be just because it's such a low voltage pack? -- Try my Sensible Email package! https://sourceforge.net/projects/sensibleemail/ ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Read EVAngel's EV News at http://evdl.org/evln/ Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA) ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Read EVAngel's EV News at http://evdl.org/evln/ Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA) ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Read EVAngel's EV News at http://evdl.org/evln/ Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
