Current measuring apparatus for battery

A resistor for use in measuring electrical current passing to and from a battery post, comprising:

• a resistor in the shape of a sleeve for being coaxially received on a battery post;
• the resistor having a first conducting surface for contacting the battery post, and a second conducting surface, wherein current flow from the battery post travels through the resistor from the first conducting surface to the second conducting surface and current flow to the battery post travels through the resistor from the second conducting surface to the first conducting surface;
• wherein the resistor has a known resistance, whereby current flow through the resistor can be determined based on a measured change in voltage between the first and the second conducting surfaces and the known resistance.

A resistor for use in measuring electrical current passing to and from a battery post, comprising:

• a resistor in the shape of a head of a battery post;
• the resistor having a first conducting surface for contacting the battery post and a second conducting surface, wherein current flow from the battery post travels through the resistor from the first conducting surface to the second conducting surface and current flow to the battery post travels through the resistor from the second conducting surface to the first conducting surface;
• wherein the resistor has a known resistance, whereby current flow through the resistor can be determined based on a measured change in voltage between the first and the second conducting surfaces and the known resistance.
