New RVIA standards are now in effect, and RV manufacturers need to understand the updated requirements.
The updated standards include:
- NFPA 1192 – 2026 Edition
- ANSI/RVIA DC Standard for DC Voltage Systems in RVs – 2025 Edition
- National Electrical Code (NEC) – 2026 Edition
The standards became effective for in-field use on June 1, 2026, with mandatory enforcement beginning September 1, 2026.
For OEMs using lithium batteries, one important area to understand is how these standards address battery safety, electrical systems, and product certification. The ANSI/RVIA DC Standard specifically covers low-voltage electrical systems and devices up to 60 volts nominal or less.
So, what changed? What does it mean for your lithium battery systems? And what should you look for?
What Changed in the 2026 RVIA Standards?
The updated RVIA standards introduce new requirements and put greater focus on the safety of electrical systems used in RVs.
For OEMs using lithium batteries, one key area to understand is battery listing and certification.
The updated requirements call for rechargeable lithium-ion batteries to carry a listing as a battery or system from a recognized third-party listing agency. Applicable standards include UL 1973 or UL 2054.
That makes it important to look beyond individual components and understand how the manufacturer certifies the complete battery.
What Do the Updated Standards Require for Lithium Batteries?
A lithium battery includes more than the cells inside it. A complete battery system can include the cells, battery management system (BMS), electrical components, enclosure, and other safety features that work together.
For OEMs, the question isn’t simply:
“Does this battery use UL-listed components?”
The better question is:
“What is the complete battery system listed to?”
Understanding the difference helps OEMs make informed decisions when they select and source lithium batteries for RV applications.
What Does This Mean for RV OEMs?
If you already use lithium batteries, start by reviewing your current battery certification and documentation.
Ask your battery supplier:
- What standard does the battery carry a listing to?
- Does the listing cover the complete battery?
- Which battery models does the listing cover?
- What documentation supports the listing?
If you’re developing a new RV platform or updating an existing electrical system, review these requirements early in the design process.
What Should OEMs Do Next?
With mandatory enforcement now in effect, OEMs should include these requirements in current RV design, sourcing, and production decisions.
If you use lithium batteries in your RVs, focus on three things:
- Know what your battery is listed to.
Confirm the applicable standard and verify that the listing covers the battery model you plan to install.
- Have the documentation to support it.
Ask your supplier for clear certification documentation that identifies the applicable battery models and standards.
- Review certification early.
For new platforms or electrical system changes, bring battery certification into the conversation early in the design process.
What Comes Next?
For OEMs, the takeaway is simple: know what requirements apply, know what your battery is listed to, and keep the documentation to support it.
In our next article, we’ll take a closer look at how to evaluate lithium battery certification claims and what OEMs should look for beyond a UL logo.
