The Battery Life setting would also need to be adjusted saisonally, and more important: it ist not the same.
Im using batterlife year round and no need to adjust it, thats what batterylife is for
If the ESS system doesnt get soc high enough it will decrease discharging percentage, so closing in on winter it will discharge less untill it will keep batterys charged, in spring it will reverse
for me this is working fine and “automated”, but doesn’t mean it will work for you! 
Yes, and it’s only for lead acid batteries and similar, but NOT for LFP batteries. I keep this setting always on “Optimized without battery life”.
It is better for LFP batteries to be kept at around 40% to 60% instead of 80% to 100% in winter time.
Setting the minimum SOC to i.e. 40% in winter and 15% in summer is the solution. And it can be automated easily.
No, it won’t need adjustments. It’ll simply raise the minimum soc (override) by 5% every day the battery does not reach 100% - and lowers it by 5% down to the configured minimum soc, when it does reach 100%.
Given the maximum it does is 75% and a used minsoc setting of 20%, it can go from min to max or other way round in 11 days.
So, ideally it would find a quite stable setpoint at for example 50% where the battery manages to reach 100% every day with reduced solar, while still having half the capacity usable for regular operation. (Within the 50-100 range, and not in the 20-70 range)
Sidenode: When using DynamicESS, you should not use battery-life, but the DESS-scheduled balancing. Else the daily changing min-soc will always cause issues with the schedule now running 5% short in most expensive (morning-)hours.
In my case the batterys will also be used during winter time (LFP) but less then in summer, so they are not always fully charged
as i said this works fine for me, doenst mean that it works for others setups
Yes, I know. And this is definitely not the behaviour which you want in summer time. You want to have the full capacity of your battery. Anyhow in summer the battery gets full every day, even when discharged to 15%.
Yeah, and then battery life won’t override your 15% minsoc for 240 days 
But when in spring or autumn you have a few days in a row without the battery getting full, it would waste valuable battery capacity.
Nonsense. It is mainly for northern hemisphere use.any chemistry works fine, it is targetting a regular full charge.
And it does so at the expense of the full usability of my battery capacity—precisely when I need it.
My objection is, therefore, by no means “nonsense.” Please try to argue a little less aggressively.
The statement that it is not for lfp is frankly. Utter nonsense.
Plenty of manufacturers actually insist it is used to ensure proper balancing.
It may not be fit for how you want to run your system, but for the majority of northern hemisphere users it is extremely fit for purpose.
I appreciate there are some extreme users and some who do consider tinfoil as a great material for a hat 
,some of those views being relevant for diy batteries, but for the vast majority on commercial batteries- BL does what it says on the tin.
Nothing wrong with over engineering solutions for, often, self manufactured problems, but its best to encourage the typical user to not reinvent the wheel unless absolutely necessary.
It’s the chemistry, that makes a difference, dude.
Lead acid batteries don’t like it to stay for long time at minimum SOC. For LFP battteries this is irrelevant.
Sweeping generalisation.
Many brands want to be frequently balanced.at top of charge, which is why some insist on battery life.
That is before you consider SOC drift due to the BMS not being able to synchronise - lost count of system outages due to empty batteries that presented a fictional SOC.
But the main motivation is that an ESS with an unrealistic minimum SOC, which it requires for its processes to work, is throughly pointless.
BL makes it clear what the optimal and available solar is for use and keeps a full battery for grid disruptions, something that is more important for many users.
It is not intended to deal with short-term weather, but for longer seasonal changes that significantly affect solar performance.
It has nothing to do with chemistry, that is not its purpose.
If you are happy to run your pack low and don’t care about grid failure, then that is your choice.
But battery life is for dealing with the scenarios facing most users and reducing it purely down to chemistry is missing the point completely.
I have NEVER seen a battery that insists that a Victron ESS has to be set on battery life. What do they do with no ESS installed? What do they do with other systems?
The SOC problems with many BMS can be solved otherwise. I myself have a JK inverter BMS which is notorious for it’s wrong SOC calculations, and which needs a balance cycle at least once a week. No problem with that.
Depends, for battery backup or peak shaving you will regularly be charging from mains.
When you have a problem and they pull the BMS logs and you have not sufficiently charged your battery you will find yourself on the wrong end of a warranty claim. Doing a few now, no quibbles because they have been treated right for both charge and discharge - though we manually charge for prolonged poor weather - BL is too slow for warmer climates and cold fronts.
Most users do not want to adjust or develop integrations. They just want the system to work, whatever happens, and if there is a fault, someone fixes it no questions asked.
The DIY user is somewhat different and certainly not the typical use case nor user.
Different approaches, but considering how many happily use BL, I wouldn’t be so quick to dismiss it. It has an application and it works fine for that.
Most users like me never charge the battery from the grid. And with a LFP battery there is no need to do that.
So they need to ask a professional to do that. But most professionals don’t know much about Victron systems, and much less know how to create NodeRed flows. And this is where this forum comes into play…
Not quite correct. Might be true for your region or use case, but for many, many more where the grid disappears for extended periods, you want a battery, by the end of the solar day, that is waaaay above the minimum SOC.
Less of a problem in sunny climates.
Chemically there may be no urgency to charge it, but load requirements often demand it.
