Sorry to bother you guys with all this stuff......... I do appreciate all the effort and info. <br><br>I'll keep my eyes posted for a repository and add a discharge recording once the repository goes online. I can put an ohmeter in series to measure the applied load w/concurrent timestamps during discharge if that would help any useful calculations. <br>
<br>Will the Q1 return parsing be changed in future versions to help interpret output like mine w/special chars and such ?<br><br>If there's anything else I can do let me know; I'll be keeping an eye on this....<br>

</div>I will, if I see this helpful. But first I want to fully understand<br>
what you're talking<br>
about it being useless.<br>

</div>What're you proposing instead?<br>

</div>Could you point me to your posts or some other place where I can understand<br>
what information is required, what is missing, etc?<br>
