More on LFP Charging
Some "sales" statements here, but also some possibly good info of interest. One thing is they found longest life (most cycles) was to charge at 14.4v but at lower amps at 0.3C. Some LFP owners o...

I have been using lifepo4 for just a year using them daily running compressor refers and TC stuff,watching numbers out of bord-om and constantly reading about them..I find it interesting that there is no number or numbers agreed on by the mass of users..
You have Will Prowse saying charge them to 100% and use them down to 0% because calendar aging will get them before the cycle count does..Then the masses on his forum argue over the best numbers for the least stress on the cells..
I have picked out a few of the most intelligent opinions(IMHO) on LFP settings from mostly DIY solar forums and saved them by there names to my phone and Victron app library setting to try for my uses..A couple/few of them post here..Example in my library MikeF/Steve/Time2 etc..They all work great but I haven't came up with a final setting for my use yet..
Everyone knows each setup is different and each person has to find his golden numbers that work best for his style of use and charging..In my case with an older TC,I just bypassed the old converter and use 100% solar and a 20 amp LFP charger for gen time if needed with my two 100ah batteries in parallel..
Most people agree with this from solacity though(I think)

To sum up, for long and happy LFP battery life, in order of importance, you should be mindful of the following:
Keep the battery temperature under 45 Centigrade (under 30C if possible) – This is by far the most important!!
Keep charge and discharge currents under 0.5C (0.2C preferred)
Keep battery temperature above 0 Centigrade when discharging if possible – This, and everything below, is nowhere near as important as the first two
Do not cycle below 10% – 15% SOC unless you really need to
Do not float the battery at 100% SOC if possible
Do not charge to 100% SOC if you do not need it
