A quick look at the SMDs shows that the user has attached six R002 (0.002 Ohms) shunt resistors across ... each of the six 12V pins should have its own shunt resistor. With the RTX 30 series ...

Wrapper functions for the milli scale. The shunt resistor is typical in the order of 0.100 Ohm. int setShuntR(uint8_t channel, float ohm) sets value in Ohm. float getShuntR(uint8_t channel) returns ...

With the shunt resistor modified, which can be done with either a bypass resistor or a custom circuit board, the only other change is to upgrade the 100 A fuse near the battery for a larger size.

The humble current shunt is an excellent way to do just that. Ohm’s Law. To understand current ... A current flows through a resistor, and the voltage drop across the resistor is measured.
