I tested one of my new "Franzbox" boards today, it works fine! I might send You one if You want to test it. (not before the end of next week, there are a few minor things to be changed in the program, such as showing the reason for the last reset and easier adjusting the tachometer for the displayed amperes) Dont expect tooo much from it, but Amperes displayed on the tachometer works very good, and the display of SOC on the fuel-gauge works good too. The resolution of metering the amperes is 3A thats good for measuring discharge and SOC, but it is not suitable for measuring 15A of charging. Dont forget, it is a +- 800A instrument, even good analog instruments cant measure 10A in a 1600A range..... for the future i'm planning a different measuring path for charging and some BMS-functions, but i am not sure if it is really necessary to reinvent the wheel, as meanwhile some really good systems are on the market or will come soon. maybe, mainly because of not having enough time, i will release the "Franzbox" as open source... This little universal-board with an Atmega can do such a lot of things, it is too good to disappear in some drawer....we will see...
