The present disclosure provides a smart connection device, a jump starter and a battery clamp. The smart connection device includes a power connection terminal, a load connection terminal, a switch circuit, and a reverse connection detection module. The power connection terminal and the load connection terminal are respectively electrically coupled to the battery assembly and the external load. The reverse connection detection module outputs, when it detects that the external load is reversely coupled to the load connection end, a first control signal to control the switch circuit to disconnect an electrical connection between the battery assembly and the external load, so as to prevent the battery assembly from providing a discharge output to the external load.

Embodiments include smart jumper cables for jump-starting a vehicle. A jumper cable is configured with an electronic control module that monitors the connection at each end of the jumper cable, and only closes the circuit when a battery or vehicle electrical system is detected as properly connected to each end. In some embodiments, the electronic control module opens the circuit when a successful jump-start is detected. In some embodiments, the electronic control module further monitors the temperature of the jumper cable, and modulates the power transfer or opens the circuit if the temperature exceeds a predetermined level.

A quick change battery clamp includes a first clamp body, a second clamp body, and a handle assembly. The second clamp body is coupled to the first clamp body. The handle assembly is selectively disposed through each of the first clamp body and the second clamp body. Each of the first clamp body and the second clamp body define an aperture having a substantially polygonal cross-section configured to receive a battery post. Each of the first clamp body and the second clamp body have an internal wall with a plurality of ridges configured to selectively abut the battery post. The first clamp body and the second clamp body are hingedly connected.

Herein is disclosed a jumper cable clamp which includes a housing having an elongated arm having a head portion and a second end configured to mount to the jumper cable and hold the jumper cable in coaxial alignment with the elongated axis. First and second jaws are mounted adjacent the head portion perpendicular to the elongated axis. The first jaw is electrically coupled to the jumper cable. The clamp further includes a lever assembly coupled to one of the first and second jaws for moving the jaw between a clamping position wherein the first and second jaws are sufficiently close together to clamp onto the terminal and an open position wherein the first and second jaws are sufficiently spaced apart to permit the terminal to be free from the jaws. The clamp further includes a lock mechanism for locking the first and second jaws in their clamping position.
