Lithium is so simply, the language of batteries is volts and amps, not profiles. Here is what you do if your serious about going lithium.
Get a proper programmable charger like sterling, victron etc. Redark gear is aimed towards those who drink the bms koolaid.
Have some acess to cell voltages and learn about the voltages and watch em every now and then. Without cell voltages you are going blind as they tell you straight away what you batt is doing. Monitors and fancy management usually lie, but volts never does. Pack voltage is good if your cells are all well.
You must know how to differentiate between:
All radically diff but once you master them bang! You can straight away know what you batt is doing anytime.
For longterm storage you keep your li in the 40% region (about 13- 13.1v resting no loads) and as cool as possible. All cells should read around 3.2v but the voltage curve between 20-80 is so flat...You can hit 50% with the charger then manually stop once you know the volts and amps with whatever sized batt and charge rate you got. Usually charge to 13.5v at .3-.4C but cant remeber exact. Best disconnecting them in storage so there are 0 loads Or you can float them at 13.1-13.2v if you have some constant loads like fridge. Thats were the programmable charger comes in. A dumbed down power supply mode always the way to go over some canned "profile" with bs stages that do jack, an example of ps mode is setting both absorb and float to say 13.5v for a set and forget. For solar you can disable the smarts as the are geared for daily cycling more.
Really the big mistake is going lithium without doing some sizable research. Master battery charging with lead acid first, then once you know go li. Sorry to say but you must learn the basics, ohms law, cc/cv physics etc. Then you will see just how uninformed the masses are. Both lithium and lead are the same and follow the same exact rules, just slightly diff set points and maintainence. Also there are diff grades of quality so cheap stuff lived much of the time at full wont last as long like good quality.
Beware of those who may lack the realworld experiences...buwhaha... seriously battery recovery??? If you let the pack voltage fall below 12.2 resting or a cell below 2.8v that is plain neglect.
Good thing about lead acid flooded i let it drain down to 4v over weeks from laziness and hit her with my enerdrive in ps mode and then equalized and she was back up and running, albiet maybe some loss in capacity.
For causal users Li can be cycled right down to "empty" no probs. I usually stop at 90%dod to get best bang for buck and leave a small amount if reserve.
And yeah like steel wool rubbed a few times across highly polished 0.1mm thick stainless sheet, this aint even scratched the surface. The bms is a can of worms and is so misunderstood
