I just connected a brand new Victron IP67 12/17 charger to my LFP bank (down in my basement for now) and set it up for LFP. I let it rip! It was off to a great start, then stopped very early. Turns out when the app says it's outputting 14V, the DMM and BMS disagree and say its a good 0.35 volt lower. The graphs in the app think it hit 14.2 and switched into "storage."
This is about the most simple LFP battery charger ever. There don't appear to be any calibrations or the like, and I just used the built in LFP profile, which looks to be pretty good.
