Rather than take the chance, I think I'll stick to single PROTECTED battery rigs. After all, there's still 9471 different PV's I still CAN use with no sweat............

Sorry I have not posted a response from MV. For some reason they have not replied to my ticket
Here's the latest post on the situation:

Ok, I did get a response from MV on the LiFePo4 batts. They are requesting the info from the supplier and will update the page with the info. Thank you Mark for responding to my ticket
I asked Carolina Vapors about a couple of batteries. Here is my question and their response:
Hi,
I would like to know what the C rating is on a couple of your batteries. The RCR123a 3v LiFePO4 part #58 and the Tenergy RCR123a 3.0v 900 mah.
Their response:
Hello and thank you for your inquiry!
There isn't an official "C" rating of LiPOs because of their inherently stable chemistry, that I have been able to find. Tenergy themselves do not list a C rating of them. That said, there is some evidence they would have a C rating between .5 and 1, which would make them a 1-3 amp battery. This only means they will provide optimum output and performance at 1-3 amp draw. They still work just fine with mods as long as they are being stacked properly and safely. LifePO batteries are a little more forgiving when it comes to safety but they still can fail if treated improperly. As long as a person practices proper battery stacking procedure, (ie. label each pair as a pair and only use them as a pair, charge and discharge together, allow an hour rest before and after charging, and alternate the "top" battery position with each cycle), they are the most safe method of stacking batteries.
The C rating of the Tenergy RCR123A Li-Ion batteries is 2C.
Hope this helps.
Thanks!

In regular lithium, I think part of safe handling is checking the voltage both before and after charging. I don't see anyone talk about that here. When one lithium is charged and another one is not and they are in a series, that is the cause of danger. One starts charging the other and poof. Dispose of any beyond the 2.7-4.2v (normal lithium) range.
I check them with a voltmeter every charge. I have had some fall out of spec.
