- Current Shunt resistors

You instruct in readme to remove 6 of the 4Mohm resistors.

In the Battery Gallery it looks you use the following BMS (single side) SKU: SP15S001V1-12S-Li ion-30A

So we have to remove only 1, correct?

- Shunt voltage fix

The 2 smd resistors has to be removed on/for the 12S4P 30A BMS Version?

You want to be left with 1mOhm shunt resistors, however you achieve that. 30A version has resistors on both sides too.

Yes the small SMD resistors must go, they cut the shunt voltage in half.
