Hello Folks.
With the not so widely available LEM CAB 300 (or Lem CAB 500) sensors, relatively high prices, and the general disadvantage of the accuracy of Hall-Effect-Sensors (see here), I am leaning towards a Shunt-solution for accuracy, for the wider availability, and for the potentially lower price. Currently I see no disadvantage using a Shunt sensor, compared to the hall effect sensor.
My question is: How to connect a Shunt sensor to SimpBMS?
Doing some quick product search, I found two potential interesting Shunts:
On another forum (see here) I found a reply from Carel Hassink, that the J2 connector would be used for analogue shunts, which I guess is the kind of Shunt I'm talking about, isn't it?
Looking at the current SimpBMS manual (V.0.22), page 9, J2 shows a connection to a hall effect sensor, if I'm not mistaken.
Can anybody (or You, Carel) please clarify on the Shunt topic in general, and specifically on the ones linked above?
Thank you.

- This shunt an an example, which seems to be of a relative high quality.
- An alternative could be the Victron SHU500050100 shunts, which seem to come with the BMV battery monitors, and seem to be sold independently. I assume, the SHU500050100 could be used without the BMV monitor?
