I'll have 900ah of LiFePo4 using a Victron MultiPlus-II 12/3000/120-50 2x120V in an RV Trailer. 1280 Watts of Solar. I'm hoping to use the Cerbo GX with a display. Looks like there are several Shunts I could use. BMV-700, BMV 712, Smart Shunt 500Amp or Lynx Shunt VE.can. Some have Bluetooth some don't. I may use the Lynx Distribution blocks. Why would I want to use the Lynx Shunt ($350) over the less expensive shunts?
