The Ultimate Dual Battery Install Kit | Toyota Prado 250

Looking for a no fuss dual battery solution? Here it is! Built to suit the new platform properly—no universal brackets, no wiring guesswork, no chasing parts mid-install, no massive fit out bills. This is a complete dual battery solution for the Prado 250, centered around the proven REDARC BCDC Alpha 25A. Designed to charge efficiently from your alternator while also supporting solar input, it gives you reliable power management whether you’re touring or running a full accessory setup. The kit is built around our vehicle-specific under-bonnet battery tray, keeping everything mounted where it should be—secure, serviceable, and out of the way. The dedicated BCDC mounting bracket positions the charger correctly for airflow and protection, rather than leaving it floating wherever it fits. Included midi fuses and a complete wiring harness take the guesswork out of the install. Cable lengths, terminations, and routing are designed for the Prado 250, so you’re not cutting, extending, or making it up as you go. It’s a clean, straightforward install that actually looks like it belongs in the engine bay. For those wanting a full setup from day one, there’s the option to include a 120Ah lithium battery—giving you a complete, ready-to-run system capable of powering fridges, lighting, and accessories off-grid. Everything in this kit is designed to work together. No mismatched components. No shortcuts. Just a proper dual battery setup, done right.
