You like to save some money Steve, how many do you need?One thing to note especially, the Shunt provided by Chargery is one of the fairly cheap ones and has no mounting / backing. I'm going to use a Deltec 500A/50mv Shunt instead, which is a far better solid brass unit. Ebay link below but check around with solar suppliers etc.
Ironically, I have the identical already in my E-Panel attached to the Classic-200 but that is connected to the WizBang Jr. interface which is between the FLA bank & LFP pack. One option is to reprogram it for the LFP and run a long lead (6' or so, might not be so good) to also connect to the BMS so it can do it's thing and have a separate shunt for the FLA bank with an independent monitor. But then that kinda messes up when I get more LFP and another Chargery BMS or two with their own relays etc... more pondering to do...
