RV and caravan manufacturers are making lithium standard equipment — factory-installed before the vehicle leaves the line. The buyer is not a dealer or an end user: it’s the OEM purchasing department signing model-year battery programs. This page covers factory-fit LiFePO4 battery supply for RV and caravan manufacturers: the standard configurations, vehicle integration protocols, and OEM program mechanics.
The Factory-Fit Standard: What OEMs Actually Buy
The industry has converged on a standard factory configuration:
| Configuration | Typical spec | Application |
|---|---|---|
| Dual 12V 100Ah | 2× 12V 100Ah LiFePO4 (2.56kWh) | Standard motorhome/caravan fitment — the volume OEM SKU |
| Single 12V 200Ah | 1× 12V 200Ah (2.56kWh) | Compact installations, single-battery compartments |
| Upgraded banks | 2× 12V 200Ah+ or 24V systems | Premium models, off-grid packages |
Public industry examples show the pattern: manufacturers announcing lithium as standard across model lines, with 12V 100Ah-class batteries as the base configuration. The exact specification — capacity, BMS features, enclosure — is defined per manufacturer and model year.
Vehicle Integration: RV-C and CI-BUS
Factory-fit batteries are not standalone products — they integrate with the vehicle’s electrical system:
- North America — RV-C: the RV industry CAN protocol. Batteries reporting state of charge, temperature, and faults over RV-C integrate with the coach’s multiplex systems and displays.
- Europe — CI-BUS: the caravan/motorhome standard for habitation-system integration. European OEMs expect CI-BUS-compatible battery communication.
- Physical integration: European motorhomes often mount batteries under seats or in compact lockers — enclosure dimensions are defined to the millimeter per model. North American Class A/B/C coaches have dedicated battery compartments with defined footprints.
- Warranty alignment: the battery warranty must align with the vehicle’s warranty terms — a 2-year battery warranty on a 5-year vehicle warranty is a manufacturer problem, not a supplier problem. Terms are negotiated per program.
Model-Year Program Mechanics
OEM battery supply runs on the vehicle industry’s calendar, not the spot market:
- Model-year contracts: manufacturers commit to annual volumes per model — the battery supplier plans cell procurement and production slots against the forecast.
- Engineering validation: packs are validated in the vehicle (fit, electrical, thermal, EMC) before series production — typically 6–12 months ahead of the model year.
- Certification per market: target-market certifications (CE, UL 1973, and similar) are confirmed per program against the destination markets.
- Change management: any cell, BMS, or enclosure change during the model year requires manufacturer re-approval — supply consistency is contractual.
What LJY Energy Supplies to Manufacturers
LJY Energy coordinates factory-fit LiFePO4 battery packs for RV and caravan manufacturers — 12V 100Ah-class packs as the standard OEM configuration, with BMS communication (RV-C/CI-BUS), enclosure dimensions, and certification packages defined per manufacturer program. No supply relationship with any vehicle manufacturer is claimed or implied.
What an OEM program confirms: vehicle models and annual volumes; pack dimensions and mounting; BMS communication protocol; target-market certifications; warranty terms; delivery schedule and logistics; commercial terms per program.

Frequently Asked Questions
What is the standard OEM battery configuration?
2× 12V 100Ah LiFePO4 is the industry’s volume factory-fit configuration for motorhomes and caravans — with BMS communication matched to the vehicle’s protocol (RV-C or CI-BUS).
How far ahead do OEM programs start?
Engineering validation typically runs 6–12 months ahead of the model year — engage early in the product development cycle.
Can you match our existing battery compartment?
Yes — send the compartment dimensions, electrical requirements, and communication protocol. Packs are engineered per manufacturer program.
Which certifications do you support?
Certification is confirmed per program against your target markets (CE, UL 1973, and others). State the required list in your inquiry.
