Just learned a valuable lesson when I set up my new LiFEPO4 house bank on my boat this week.. Last year my house bank was FLA batteries and I used the VIctron Smart 100/30 MPPT and Smart Battery Sense on this bank; Worked great. This year I replaced the FLA with 2 100AH Battle Born LFPs in parallel and installed the BMV712 with 500A Smart Shunt and Temp Sensor, as well as the Orion 12/12-30 between the sole FLA engine battery and the new house bank. I hooked up the Battery Sense to that battery. Then, powered up the system and got some very high V readings off the BMV. THEN I remembered that I had networked the Battery Sense and MPPT on the old battery bank. I reset the network to include the MPPT and BMV and everything worked just fine. End of lesson.
