Hi Matt, I typically like to keep battery monitors consistent with inverter manufacturers. Outback and Schneider Electric and Magnum offer good native battery monitors that, when tuned in correctly, work well with LFP.
That being said, I have definitely used the Victron BMV 712 paired with SimpliPhi and hand full of times with great results. It’s a shunt based monitor with easy installation and Bluetooth connectivity. Accuracy is nowhere near closed loop, however if programmed correctly, it’s a helpful addition. I do wish that SimpliPhi would develop a plug in BMS display for their AmpliPHI series, similar to the Discover AES Link. This is where the Fortress eVault really gets it right.
