Unreliable Flash Discharge K20

I have a Sunpack 555 and it is connected via dedicated sync to the hot shoe. It is powered via Quantum BAttery 2.
The ready light will glow and flash fire 80% of the time with the missed flash most often right after the flash has just fired. In each case the ready light is on and after 3 seconds or so. To verify this problem I have switched flash units to the second Sunpack 555 and tried the 1st D too. Yes I have switched out the sync cord to the household plug as well.
Looking for suggestions...
I want to buy a 540FTZ but not if I will have the same issue.
