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