Lifepo4 float setting?
I have not had to deal with a float setting so far with PWM controllers but I have a Victron 75/15 coming tomorrow and reading up on the settings,it is confusing especially the float setting..Some say...

What are you striving for? Absolute max cell longevity? Max usability/ah capacity? Or, somewhere in-between?
If you want absolute max cell longevity float a 12v lifepo4 at ~13.15V (~50% SOC). Downside, minimal usability/ah capacity.
If you want max usability/ah capacity, float the battery between 13.6 - 14.4v (~99 SOC). Downside, some reduction in cycle life. More so as you approach 14.4v. Floating at 14.6v is not recommended.
Can't have your cake and eat it, too. Pick your poison.
Well put...Something in the middle I guess realizing I can change the settings if need be for certain scenarios..So other than the occasional cell balancing,what bulk charge voltage should be set at if your battery settles at 13.3/13.35 after a 14.4 charge.
