Fully charged when I received them in mid October, I discharged and recharged one cell five times, the capacity is around 5.6A based on my B6 charger (my 10yo B6 does need an upgrade to 1% resistors for voltage reference, it does show an error of 0.1 - 0.2v margin)
Looks very interesting. I am getting sick and tired about the bad availability of the Zippy LiFePo4. Have you soldered them together or do you use a spot welder? Have you got a photo of the complete pack ready to use? 73 John, DK9JC
I used a spot welder, quick and dirty built with parts laying around in my shed, the only cost was a cheap timer board from China for setting 150ms firing.
There are mixed reports from many users. All played on their own risk, including myself.
AD6DM, claimed as first experimenter, his pack 4S2P failed to his expectations.
What is the C rating for these cells?
According to this descrition on a buying site it would be 5
“LiitoKala 3.2V 32700 7000mAh 6500mAh LiFePO4 Battery 35A Continuous Discharge Maximum 55A High power battery+Nickel sheets”.
