The second was a battery discharge test. It would apply a small known resistive load and then record voltage drop and give an assessment in % of battery capacity. Both of these (and more) could be easily integrated into the new module. So - what new cool features can this thing do that, beyond just a replacement for the contractors, would add to a pilots confidence in the health of the airplane?

This would be a very cool feature Bill...one that I will put on the list of "upgrades" we may be able to do with the PPS down the road...first we need to get the unit in to production based on the original design parameters.

I'm not sure how to turn your life in to rainbows and unicorns, but we can make things more reliable than any mechanical device could ever dream of. We aren't focused so much on the cost of what we are replacing. We know we can't touch that price point, but we are focused on is safety, reliability, and ease of installation. The dollars worth of wow are in the eye of the customer who wishes to use solid state products.

This is being discussed and may be an easy solution...I'll know more about this soon.

Something to look in to for sure...it's not something that fits the current scope of products from VP, but I do keep a list for potential development projects. Thanks!

ALT 1/2 is from Regulator in some cases
Going back to the comments on the Alternator 1 and 2 B leads being connected to the same lug:
In many cases, it is not the alternator that is being connected, it is the Regulator output. How does the PPS handle this scenario (such as with the ULPower 520is)? Should both alternator outputs be connected to this lug? I presume the guidance in the VP-X documentation for the installation of a protective relay for the regulator feed (page 30) does not apply when using the PSS?

You have some bad information. The PPS has been under flight testing for several months. The reliability has been excellent with tweaks, adjustments and a few mods taking place. Overall the product has worked as designed.
The selected Beta units will be shipping in the next week. Several will be installed and flown quickly adding more hours to the test program. Ballard is a quality company that will not release the product until ample testing and high reliability is achieved. The Beta testers will use and recommend any changes and mainly put hours not he product.
Hang in there!! This will be a quality product and will be worth the wait!!

I kinda wish quotes showed the date of original posting. If you look back you'll see that statement was made in May when they were advertising a 3D printed mockup.
I do see a manual posted with a July date, although it's full of TBD.
http://verticalpower.com/docs/PPS_Manual.pdf
From what I can tell, the unit doesn't have any alternator control logic built in, it doesn't handle split buss systems, and I don't see any details on the overload protection.

Yes, whether B lead or reg output, both would go to the B lead post.

99% correct...except the PPS has been in ground and lab testing for several months, flight testing begins this month.

Please do not use that manual for anything...the page you pasted is a cached page that has been removed if you refresh your browser on the docs page. That manual is for the original prototype from several years ago. The new manual will be posted once we get through beta testing this fall and winter.

Perhaps they realized the business case just wasn't there?

Hi guys,
It's still coming...we have had some challenges with getting it working reliably. This was a much bigger nut to crack that anyone anticipated, but engineering meetings are still occurring on this on a weekly basis. The beta units are still being tested, and beta test 2.0 (not official, that's just my version of it) is going to see the mods integrated.
We are still shooting for the 2nd quarter 2017. I will be at the factory in January and I'll have a much better idea at that point.

Ouch. Not the expected timeline. Kinda means back to the drawing board for many of us builders.
