Thank you for viewing. This is a KIV14SQ cable with a 30cm length and crimp terminals for parallel battery connection. Terminal sizes are selectable from (14-8, 14-10). If no size is specified, we will ship with 14-8. The main use is for connecting two batteries in parallel, and this length is optimal. Wire current capacity: 88A/600V, so you can use it with confidence even with large currents. For parallel connections, the two wires need to be the same length. Please feel free to ask if you have any questions. This product comes with free shipping nationwide.
