I bought these from Alibaba.
I'm convinced they are not new batteries.
The Specs say normal voltage is 3.2 (12.8v) and Charging Voltage is 3.65 (14.6v).
The best charge I can squeak out is average 3.47 or so out of each cell.
After the last charging cycle my battery float was around 13.7. I disconnected PC voltage and I'm reading 13.74
They were charged by a Victron 100/30 SCC with these parameters:
Every SOC I've ever seen for LifePO4 shows 13.6 as 100% charged.
What would be your opinion of these batteries?
Also I've never done a full discharge on them. Should I do that and charge again? Would that make a difference?
My opinion of these batteries is, and please tell me if I'm correct is that they are used but still in pretty good shape.
I'm not real happy with Alibaba but thinking these are still pretty okay.
Or I've done something stupid and missed something. In which case tell me. I can take it.
