Hi Snakebite,
If I understand you correctly.
You are saying “Tenergy LiFePO4 32650 3.2V 5500mAh Rechargeable Batteries 5.5Ah”
were made 9th week of 2013 and do not hold 5.5Ah as stated?
Have you got links to tests, or aware of the true specifications for these cells.
Also, what are these lico 5.5 ah you got?
Can you share what you purchased and who supplies it?
Cheers
