Im reviewing the settings on my old Epever Tracer, which has no lfp setting so its set to user. Don't remember when I set it, my brain is a small percentage of whatever it was. Appreciate any guidance. Seems to be working fine for some reason.
Over disc 14.0
Charge limit 13.8
Over reconnect 13.6
Equalization charge 13.8
Boost charge 13.8
Float charge 13.6
Boost reconnect 13.3
Low reconnect 12.6
Under reconnect 12.2
Low disc 11.1
Discharge limit 11.0
Equalization time 0
Boost time 180 min

You seem to have an older version of the software with different names for some settings. You may have to do some googleing to connect the dots. Here are the basic settings I used.
Absorption Time = 240 min (boost time)
Over Disc = 3.475 per cell (13.9V)
CC bulk = 3.45v per cell (13.8V)
CV absorption = 3.45v per cell (13.8V)
FLOAT = 3.3V per cell (13.2V)
Boost Reconnect 3.15V (12.6V)
LVCO-3.1v per cell (12.4v)
Those numbers are pretty conservative and more about extending the life of the batteries than maximum power.

Thanks Trav. Pretty similar to what im doing. And lower than what epever lists for their lfp settings on their AN controller.
I’ve decided to keep that spare Siemens bank feeding the cabin bank lfps, it kicks in about an amp. Its hooked to my spare Tracer, now set at FLP. I cant just hook it to my main Tracer ive read because of the differences in panel voltages (80 or so vs 34) without rewiring.
The other option would be to just set it to GEL.

So many of the old recommendations for boost on LFP was 14.6 for a 12v bat, more than I want to go.
Iirc Steve_S recommends 13.8 for a regularly cycled bat (as in a solar set up), for my 'charge at home' Ive been using 14.2 so the BMS has a chance to do some cell balancing, seems to be working as Im getting more beans out of my bats.
