Battery Bank Wiring Kit

Description

This wiring kit includes everything you need to connect 12V batteries together into a battery bank (Batteries not included, but can be purchased here). Kits vary in range from 2 battery bank kits to 8 battery bank kits and 12V or 24V options. Select the appropriate kit for your needs. See videos below for installation instructions.

Pre-Crimped (PRO) vs. Un-Crimped (DIY)

Pre-Crimped (PRO): All cable ends are professionally crimped, labeled, and heat-shrunk by our team for a clean, ready-to-install setup. No crimping tools or extra prep needed—just connect and go.

Un-Crimped (DIY): Includes the same high-quality components, but cables arrive with loose terminals for those who prefer to cut, route, and crimp their own connections during installation. Perfect for full customization or unique layouts.

✅ Choose the Pre-Crimped (PRO) version of this wiring kit to receive cables with terminals professionally crimped and finished by our team. You’ll get the same high-quality components, with the added convenience of ready-to-install cables—perfect for those who want a clean, professional-grade installation without needing to do the crimping themselves.
