Hey there folks, I just picked up a Ford Ranger EV that was swapped with LiFePO4 about 5-6 years ago, and was parked shortly afterwards and never used again.
I just got a 12v battery in the truck and plugged in the diagnostic tester and got a SOC reading that shows as about 15%. Based on some guesstimation, depending on whether the truck is "set up" as a Lead acid or NiMH that would put the voltage around 290v or 250v respectively.
The LiFePO4 pack in the truck is most likely 105s, though I haven't gotten the chance to open it up yet to see. But taking that into consideration, that would put the average cell voltages around 2.8-2.4v. Based on what I've seen from other people's experiences, they will probably be all over the place with some in the 3v range, and maybe some as low as <1v...
My question is, what do you think the viability of reviving this pack might be, and what method would you go about doing it? I know each cell should be recharged individually, but what should I charge them to, and at what rate should they be charged? Should I capacity test them when I'm done getting them up to voltage?
