Electrical

Shop electrical components for charging-system and car audio builds, including alternators, batteries, capacitors, cable, fusing, voltage control modules, and installation hardware.

A charging system works as a set, not as individual parts. Output capacity, battery reserve, cable gauge, and regulated voltage all have to suit each other. Adding amperage without upgrading cable, or adding batteries without adding charging, usually moves the bottleneck rather than removing it.

Start with high output alternators, then batteries, cable and wire, and voltage control. Our alternator sizing guide covers how to calculate what your build needs.
