I have in use the sph6000 and diy lifepo4 batterry.
I use the lead-acid battery seting for this , but i manage the xharging/ discharging and protection with a daly bms.
If you will use this pair ,be sure to have the cut charge and disharge of the inverter set in such way that the inverter will stop the process and not the bms.
If the connection is intrerupted by bms you will have to manualy reconect.
I have used for 5 monts, not big problems till now.
I will not recomand to people who prefer plug-in and forget about it.
