Volt meter and such.... looking for a data panel...
i've been hunting... clicky right heee-a! let me know what ya think. pretty straight forward, no?

The main reason for using a shunt instead of a hall effect sensor is cost.
The cost of making a shunt is only a few cents, whereas the cost of a hall effect sensor (1,000 piece price from Analog Devices) is $2.47. Add the cost of the additional components and the retail price for the hall effect meter would be about $40 more than the shunt meter.
When using a shunt meter, the shunt should be installed as close to the battery bank as is possible; this reduces the IR drop in the wiring. The wires going to the meter can be quite small because they carry very little current (µAmps).
With a hall effect meter, it is sometimes necessary to use shielded wire for the connecting wires.
