You checked the right place, all you need now is to read the values in your screenshots :-). Everything other is well described in the In your case the battery SOC did not yet reach the A good strategy is set by default. Everything you want to change is based on your taste. |

I think my issue was that I thought I could set things like this in the BMS, and everything would flow from there. But as I'm no stranger to config files, loved them for 30+ years now I just have to change my mindset from the Android app back to good ol' config files. :) Thanks. The default file is nicely commented, thanks for that as well. |

Hi, I have a JK BMS connected via CAN to a Raspberry Pi 3b+ running Venus OS 3.52.
I charged my 4S battery and it switched into Float (Linear Mode), nice. The MPPT in my testrig is controlled by the BMS via Venus OS.
I then consumed 20 Ah from the battery, and Overview -> Batteries -> Serialbattery(JKBMS CAN V2) -> Parameters says that it's still in Float (Linear Mode) when I would expect that it would switch into Absorption already.
I'm now consuming another 20 Ah to see if I reach a threshold of some sort.
When will my BMS or Venus determine that it's time to switch to Absorption / Bulk or whatever?
Is there a table available that would explain which setting in JK BMS affects which of CVL, CCL and DCL? I played around with the values in JK BMS and tried to get my CVL increased to 14.0 V in Absorption without really getting which parameter to change in the JK BMS. I couldn't quite figure out if the settings in the JK BMS or the settings in config.ini takes precedence, I suspect the config-file overwrites anything coming from the JK BMS am I right?
edit: I have CMCM_ENABLE not enabled in config.ini. I find it a bit confusing for now to both configure the BMS and then also dbus-serialbattery with voltage limits. What is a good strategy here? Should I use configure.ini as well and configure SOC_LEVEL_TO_RESET_VOLTAGE_LIMIT there and not try to get this from the BMS?
Many thanks to everyone giving their time to this project, really appreciated!
