Not sure what info you are after regarding the profile, but the info I wanted is in the manual here: The LifePo4's get a max 14.6v and no float voltage https://www.redarc.com.au/Content/Im...n%20Manual.pdf

The issue with most of the DC-DC chargers on the market that are not LifePo4 specific is that they simply cant handle the constant current demand when charging and will overheat and shut down or fail. LifePo4 will pull every amp you can throw at it out of the charger, some simply can't keep up with the demand. I know the Redarc I am using gets bloody hot when I work it hard, so I am surpised it's still going. There are a few LifePo4 DC-DC chargers beginning to appear now, Sterling BB1260, Enerdrive DC2DC, GSL Electronics, Redarc, these are all pretty similar in that none of them have individual cell management capability. I use a BMS from EV Power in conjunction with individual cell balancing modules as in the picture of my battery below. My HV/LV will shut off supply at 14.7v and LV at 11.6v (User settable) This is really only a back up in case the BMS fails to do it's job.
