Lithium Battery Settings

PixandMsBee

Just received an SOK 100ah LifeP04 battery, heated with bluetooth. After some assistance from YouTube I have it up and running!

I am having trouble configuring all the settings though and getting it to fully charge which I think means that it should read 14.4 volts while I am only getting 13.5.

Now the details:
2022 320-S Boondock
WFCO WF8735-Lis distribution panel / charger (charges up to 35-amps according to WFCO) (Original equipment)
Victron Smart Solar HQ21051E7B8 MPPT/10 controller (Original equipment)

Software:
Victron Connect
ABC-BMS  which is the SOK App.

I have been charging the battery installed in the trailer with it plugged into shore power as well as the 100-watt roof mounted solar panel charging.

My issue is the settings that are available in Victron Connect, I am unsure of what the setting should be, there are so many variable and so many differing opinions. Even the recommendations directly from SOK do not appear to be available.

The ABC-BMS app said that the battery is 100% charged though it said the voltage was 13.5.

The battery is supposed to be run through 2 complete cycles before using to get it calibrated and I am reluctant to do this until I see it has reached 14.4 -volts. 

I currently have the T@B unplugged from shore power and have connected a 3-amp LifeP04 charger directly to the battery in the hopes that it will bring it up to the proper voltage before I initiate the first complete discharge.

The WFCO panel has a switch that has been set to "LI", the Victron APP has been set to LifeP04.

I am hoping that someone can list the rest of the settings that should be entered in the Victron Connect App.

Thank you for any assistance that you are able to provide with this issue!

If the battery reads 13.5 - after the charger is disconnected and the battery has “rested” for a few minutes - I think you’re at full charge, though I’m not familiar with that particular battery.  When charging it should read 14.4, but not after it’s fully charged and rested a bit.

I charge my 12v LiFe at 14.5 and float at 13.6 per manufacturer’s instructions.

14.4 to charge ,,, 13.5 is full  LifeP04 battery

In your SOK manual there may be a whole chart of different "parameters" for battery charging.  If your Victron app is giving you 13.5 volts, your battery is charged.
The charger may not have needed to provide 14.4 volts because the battery may not have needed that many volts to charge from say, 90 percent charged.

Thanks for the information though I am still trying to find the details of how to set up the Victron Controller. As far as a manual for the SOK battery, it does not come with any information and the very little that is on their website does not correspond to what I see in the control apps.

What what settings in particular are you concerned with?

This link, under Charger and Inverter Settings has lots of the battery parameters.  There are some numbers for the Victron shunt, but I'm not sure if the Victron controllers have the same "manual" setup.

In the Victron Connect MPPT manual, section 5.1.2 shows where you can set the different battery parameters. Look over the Expert Mode, and compare the settings to the "battery parameters" in the SOK page above.

Thank you so much, this is very helpful! The SOK website has very little information as does the Canadian distributor that I purchased from.

@PixandMsBee, Send an email to sales@sokbattery.com and ask them for the Victron parameters.  They sent me a detailed table, but I can't seem to find it.
