My Quattro 48/8000/110-100/100 does not have a CV-CC charge curve for my lithium battery, so I set the voltage limits appropriately, but the three charge phases meant for lead-acid are irrelevant, and in some case, reduce the charge current inappropriately. Is there a way to configure it just for CV-CC? My firmware version is 206.
Hi hyboot.
Firstly if at all possible I would recommend updating the firmware of the unit as 206 is a very old firmware version. You would likely be required to use VE.Flash to update the unit to the latest firmware versions however.
As for your question lithium batteries can be setup to charge CC-CV by charging the following settings in VE.Configure.
First is to setup the battery monitor for SOC calculation. On most lithium batteries an efficiency and end of bulk value of 0/95-1 should suffice.
Secondly with an updated firmware the software will give you the option of a lithium charge curve, that you can change as is needed. 
If you cannot update the firmware for any reason you can also set the charge cure option to "fixed"
And set the Absorption and float voltage to the same value, as well as setting the absorption time to 1hr. Also disable equalization and adjust the temperature compensation to a lower value. Just note that the battery might be charged even bellow 0 degrees. this will essentially set up a CC-CV cure that will push current into the battery until the set voltage and then keep it there.
Thanks a lot.
If someone can tell me the version number appropriate to my Quattro, and the link to it, I could try.
Thanks in advance.
