As you develop or source recreational vehicles, the battery system determines user experience, operational reliability, and lifecycle cost. Wirentech provides commercial-grade Lithium-ion RV Battery systems engineered for house loads, auxiliary systems and hybrid on-board power in motorhomes, travel trailers and camper vans. Founded in 2016, Wirentech combines a 10,000 m² production facility, 20 lines of production equipment and a dedicated R&D team with BYD experience to deliver scalable LiFePO4 and modular battery packs tailored to your vehicle architecture. If you require technical datasheets, vehicle compatibility checks or sample evaluation units, you can start the conversation here: Contact Wirentech.

Why Choose Lithium-ion (LiFePO4) for RV Applications

When you compare lithium-ion (specifically LiFePO4 chemistry) to lead-acid or AGM options for RV service batteries, several performance and business advantages become immediately relevant to your procurement decision. First, LiFePO4 delivers substantially higher usable energy per kilogram: you can reduce battery weight and reclaim payload or extend vehicle range for the same installed energy. Second, cycle life is orders of magnitude higher — typical high-quality LiFePO4 packs sustain thousands of cycles with controlled depth of discharge, which translates to fewer replacements and lower total cost of ownership over the vehicle life. Third, LiFePO4 accepts higher charge currents and recharges faster from solar arrays or alternators; that reduces dependence on shore power and increases autonomy for your customers. Finally, LiFePO4 packs require zero watering and minimal maintenance, a critical operational benefit for fleets and rental operators who need predictable reliability. Wirentech’s packs are designed and tested to meet these expectations and to integrate with common RV power architectures; for a direct evaluation of how LiFePO4 transforms your product offering, please request a technical consultation.

Typical RV Battery Configurations and Technical Parameters

You will typically specify RV battery capacity by voltage and amp-hour (Ah). Common configurations we supply and support include 12V house batteries (12V 100Ah Group form factors), 24V and 48V modular banks for high-power coach installations, and multi-module systems for towable trailers. Key parameters you should evaluate are nominal voltage, usable capacity (Ah and Wh), continuous and peak discharge current, cycle life at defined DoD, operating temperature range, physical dimensions and BMS capability. Below is a practical reference table we use when advising OEMs:

These configurations represent common starting points; you should specify target runtime, average load profile and desired autonomy so we can recommend the optimal capacity and module count. For precise cell selection, mechanical interfaces and BMS options please ask for a compatibility assessment.

How to Size an RV Battery Pack for Your Vehicle

To size a battery pack for an RV you must quantify the average and peak power demand of onboard systems: lighting, water pump, refrigeration, HVAC, inverter loads and ancillary devices. A recommended process you can follow is: (1) list all continuous and intermittent loads and their wattage; (2) estimate daily operating hours for each circuit; (3) sum daily energy consumption in Wh and include a reserve for inefficiencies (inverter losses, wiring); (4) determine the target depth of discharge (DoD) — for long life we recommend designing for ≤80% DoD for LiFePO4; (5) select a battery capacity that meets daily Wh requirement divided by usable DoD, with allowance for solar input or alternator recharge. For example, if daily demand is 4 kWh and you target 80% usable DoD, the pack should have at least 5 kWh nominal capacity. Wirentech provides technical support to run these calculations for your vehicle, model by model; share your load profile with us and we will produce a sizing sheet: Request a sizing worksheet.

Customization, OEM & ODM Services

You may be integrating batteries into new RV models or sourcing for aftermarket supply. Wirentech supports both OEM and ODM workflows: custom mechanical housings to match battery compartments, branded labeling and packaging, tailored BMS firmware and communication protocols (CAN, RS485, Bluetooth telemetry), and packaging optimized for logistics. With our RD team — experienced former BYD engineers — we provide cell selection, thermal management (air-cooled or liquid-cooled options), aluminum welding automation and full prototype cycles. Our factory footprint of 10,000 m², 20 production equipment lines and a multidisciplinary engineering team ensure we can scale from pilot runs to volume orders. For OEM roadmap discussions or to request a custom BOM, contact our team: Start your OEM project.

Charging, BMS Integration and Vehicle Electronics

Charging strategy and BMS integration are critical to longevity and safety. LiFePO4 batteries require charge voltage and current profiles different from flooded lead-acid batteries; when you integrate Li-ion packs you should validate alternator regulation, shore power charger compatibility and inverter/charger setpoints. Wirentech’s BMS options include cell balancing, low-temperature charge protection, state-of-charge reporting and event logging. We supply packs preconfigured for common inverter brands and offer CAN-bus profiles for fleet telematics integration. If you plan to retrofit vehicles originally specified with lead-acid systems, we recommend a system assessment to identify any regulator changes or fusing upgrades—our engineering team will provide a retrofit plan and wiring diagram upon request: Request retrofit wiring guide.

Safety, Certifications and Quality Management

You must be certain the battery meets both safety and regulatory benchmarks for sale and transport. Wirentech manufactures RV battery systems under an ISO9001/ISO14001/ISO45001 quality and safety management system. Our product certifications include UL9540A, UL1973, ETL, IEC and PSE, and all modules are supplied with MSDS and transport documentation appropriate to your destination. We perform rigorous factory testing — electrical, thermal cycling, vibration, and end-of-line validation — to ensure field reliability. Provide your target markets and we will confirm which certificates and documentation are necessary for import and use in those jurisdictions: Confirm required certifications.

Operational Considerations: Durability, Environment and Warranty

For RV operators and rental fleets you should evaluate three practical factors: durability under vibration and road shock, thermal performance across seasons, and warranty coverage that aligns with expected vehicle life. Wirentech designs packages with robust mechanical fixation and optional thermal insulation or heaters for cold climates. Typical high-quality LiFePO4 systems demonstrate multi-thousand cycle life under normal use; Wirentech will provide cycle-life data for the exact module you intend to deploy. Warranty terms and available service contracts are tailored to order quantities and market; please contact sales to obtain standard warranty terms and available extended warranty options for fleet programs.

Case Scenarios and Application Examples

Real world applications vary: you may be designing a compact van conversion where weight and pack size are critical, or a luxury coach where HVAC uptime and silent operation are priorities. For example, in a medium-sized camper with a daily off-grid load around 4–6 kWh, a 48V modular pack sized at ~6–10 kWh will commonly provide multi-day autonomy with conservative solar support. For high-usage rental fleets, specifying packs with integrated BMS telemetry reduces downtime by enabling predictive maintenance and remote diagnostics. Wirentech has supported projects across Asia and Europe; our engineering team will provide documented case references and installation photos once confidentiality allowances are agreed—contact us to request references relevant to your market: Request references.

Procurement, Samples and Production Scaling

We work with distributors, OEMs and fleet operators using flexible procurement terms that accommodate sample evaluation and scaled production. If you need pilot units for validation, you can request sample modules and technical support; for larger orders we coordinate manufacturing capacity, quality checkpoints and logistic planning from our production facility. To initiate procurement discussions — including lead times, minimum order quantities, and shipping terms — please submit your project brief and expected annual volume so we can prepare a commercial proposal.
