If you are still having issues, its typically one of the following:

1) Incorrect wiring type for the balance connector being used.

2) Damaged, worn, corroded, or generally dirty contacts on the balance connector or the main leads.

3) An imbalance of resistance on either the main leads, or the balance connector. A lot of 3rd party boards and cables may have a fuse or LED on either the positive or negative leads, but not both. This causes issues with the IR readings.

EDIT: Example of PL8 showing the correct IR. The user in that thread did found that it was a due to a BuddyRc parallel board. http://www.rcgroups.com/forums/showp...0&postcount=17

Just went over my charger setup and well well well I found I was still in FMA wiring (i'm using Revo SPA charging board)

changed it to XH/EH wiring and all is good now all my cells (on this particular lipo) are around 1.7

feel pretty stupid now

BTW I'm using 3.32

Default Thread Update for those of us using the Revo MPA board

I thought I'd post this since I spent more than 5 minutes trying to find the answer...

MPA can be used with any Cellpro brand products capable of XH WIRING MODE

I was confused which mode to select today... I assumed FMA mode was meant for the Revolectrix MPA charging boards... I was getting high IR on my last cell regardless of the batteries. Came across this thread and was still confused or missed the answer... But, anyway, the answer is right on the Revolectrix website in the foot notes for the MPA board.

I'm no longer confused and getting correct IR's on all cells now.

I have the latest version 3.33 firmware installed.

Well it is six months later but the thread was resurrected so ... what the heck.

My end result issue was traces burnt. I soldered wires where the traces went and now my board works like new. If you have to repair traces on this board, keep in mind they are both on the front and back.

Are you referring to the SPA board or the MPA?

Just the 2s-6s SPA board, non-fused circa 2014.

The balance lead on the XH SPA board contains polyfuses and is good for 2-8s.
