High-Capacity Universal Battery Connector, Positive or Negative The XB-BTU Battery Connector is ideal for larger systems that require multiple power wire connections at the battery. It is capable of receiving 1/0 AWG, 2 AWG, 4 AWG or 8 AWG wire in each of its three captured-wire connection points (in any combination). OmniSert™ technology ensures secure, high-integrity wire contact. Multiple bushings are included to dress the wire exits, depending on the size wire used. The included adaptor collar allows it to be used for negative or positive battery post connections, where the secure clamping design ensures a tight fit to the battery post. Adaptors are sold separately for side-post batteries. We also include a "factory harness adaptor", which can be installed in one of the three wire connections to accept power rings and most factory harness battery terminations. 360 forged and machined brass construction with a high-temperature polycarbonate base and cover.
