I Replaced TWO Chargers with ONE (Victron Orion XS Upgrade)

In this video, I replace my existing dual battery-to-battery (B2B) charger setup with a single Victron Orion XS 12/12 50A — simplifying the system, reducing wiring, and improving efficiency. We start by looking at the existing installation (with a full circuit diagram), then strip it all back before installing and testing the new setup. Along the way, I cover some key principles that are often misunderstood, including: * Why cable lengths matter in parallel systems * Correct fuse placement and protection * Why you should never rely on a BMS as a safety cutoff * Safe isolation before working on lithium systems * Real-world install considerations on a liveaboard boat This isn’t just a swap — it’s a proper rethink of the system. As always, everything is tested at the end and integrated back into our onboard Victron setup. ⸻ ⚡ Equipment featured * Victron Orion XS 12/12 50A * Existing dual B2B chargers (removed) * Lithium battery bank * Victron monitoring system (Raspberry Pi setup) ⸻ If you’re thinking about upgrading your own system — or just want to understand how it all fits together — this one’s for you. ⸻ 👍 If you found this useful, give it a like and drop any questions in the comments — I read every one.
