Hello, I recently upgraded from 12v SLA Batteries to 12v LifePo4 batteries from bigbattery.com.
My question: Is there a software/firmware upgrade that will allow me to select a lithium charging profile on the MPPT 150/70 so the lithium batteries are charged properly? Looks like the newer "smart solar" MPPT have a lithium profile.
Right now I have setup a "custom" charge profile that has absorb @ 14.4v and float @ 13.6v, no equalize. There is no option for bulk.
