Engineered to strict ISO and CE guidelines, our customized lithium platforms serve heavy-duty industrial vehicles, golf carts, and custom RV configurations.
The global motorhome and recreational vehicle (RV) industry is undergoing a structural transition from legacy Lead-Acid (AGM/Gel) battery chemistry to advanced Lithium Iron Phosphate (LiFePO4) systems. Modern high-end caravans demand stable power grids to run energy-intensive onboard hardware—such as 12V/24V inverter-driven air conditioning, induction cooktops, dual-compressor refrigeration, and high-efficiency water heaters. This off-grid electrification trend has turned the battery system from a simple backup cell into a core engineering component of the motorhome chassis.
OEM motorhome manufacturers face strict requirements: optimizing battery storage volume, reducing vehicle curb weight to comply with regional licensing laws (such as the EU's 3.5-tonne limit), and ensuring maximum thermal safety under all environmental scenarios. LIAO Technology addresses these design requirements with bespoke lithium power designs. Our custom configurations deliver higher energy density, zero maintenance, and stable power delivery, enabling RV builders to meet consumer demand for true off-grid freedom.
LIAO Technology utilizes advanced Prismatic LiFePO4 cells to build compact packs designed to handle high mechanical vibrations. Unlike cylindrical alternatives, prismatic designs pack tighter, use fewer internal interconnections, and offer superior heat dissipation. Our chemistry is intrinsically safe, eliminating the risk of thermal runaway and preventing fire or explosion even under direct physical puncture tests.
| Performance Parameters | LiFePO4 Technology (LIAO Custom) | Standard Lead-Acid (AGM/Gel) | Engineering Benefit |
|---|---|---|---|
| Cycle Life (100% DOD) | 2,800 to 5,000+ Cycles (To 80% Capacity) | 300 - 500 Cycles | Extends system operational life past 10 years, lowering warranty claims. |
| Depth of Discharge (DOD) | Recommended up to 95% (Safe at 100%) | Strictly 50% (Max safe discharge) | Provides almost double the usable capacity within the same footprint. |
| Operational Temp Range | Charge: 0°C to 55°C | Discharge: -40°C to 85°C | Charge: -15°C to 40°C | Discharge: -20°C to 50°C | Enables safe operation in extreme winter and summer environments. |
| Charge/Discharge Efficiency | > 98% | ~ 75% to 80% | Reduces charging times and saves solar energy in off-grid setups. |
| Weight & Energy Density | 120-140 Wh/kg (approx. 1/3 of SLA weight) | 30-40 Wh/kg | Reduces vehicle weight, improving fuel efficiency and cargo capacity. |
LIAO systems use premium prismatic cells (including standard 3.2V 120Ah configurations from CATL and our own certified lines). These units undergo rigorous compression testing and direct puncture tests. In case of localized physical damage, the chemistry prevents thermal runaway, meaning the cell will not catch fire or explode.
Each motorhome battery pack features a custom Battery Management System (BMS) with CANbus, RS485, and Bluetooth interfaces. This allows real-time communication with onboard systems (such as Victron or Simarine controllers), enabling accurate State of Charge (SOC) tracking and cell balancing.
Our custom battery pack designs help optimize efficiency, lower labor costs, and improve performance across recreational, marine, and light industrial vehicles.
Our next-generation LiFePO4 golf cart batteries deliver consistent power output, helping carts easily navigate steep hills and uneven terrains.
Our LiFePO4 batteries power caravan movers quietly with zero emissions, improving efficiency and reducing labor costs during positioning.
Engineered for heavy loads and short-distance transport, our LiFePO4 packs help utility vehicles move goods efficiently while reducing maintenance downtime.
Sustainable marine transport requires low-noise, eco-friendly systems. Our LiFePO4 batteries deliver clean, quiet energy for freshwater and marine vessels.
Founded in 2009, Hangzhou LIAO Technology Co., Ltd. has grown into a leading developer and manufacturer of specialized LiFePO4 battery systems. By keeping core technological R&D and production under one roof, we guarantee complete quality control across all manufacturing stages. All operations comply with the ISO 9001 quality management system, the ISO 14001 environmental management system, and the ISO 18001 occupational health and safety standards.
Our Factory 4.0 facility features automated cell sorting, high-precision laser welding, and temperature-controlled baking systems to ensure cell consistency and pack longevity. Below is an overview of our standard assembly and quality control workflow:
We screen cells for capacity, internal resistance, and voltage curve matching before pack assembly. This helps prevent imbalances that can shorten battery life.
Automated machinery cuts and stacks electrode materials to reduce variance and ensure uniform heat distribution inside each cell case.
Solid-state busbar connections are laser-welded to minimize internal resistance and ensure secure contacts that can withstand ongoing transit vibrations.
Cell assemblies are baked under vacuum to remove moisture before electrolyte filling, preserving the electrochemistry and extending service life.
Entering international RV and industrial vehicle markets requires strict compliance with international electrical and transport safety standards. LIAO Technology products are designed to meet rigorous regulatory testing. Our logistics and engineering teams help OEM buyers navigate localized compliance requirements for smooth customs clearance and import approval.
Our products hold CE certification and comply with safety and environmental directives, enabling smooth distribution in the UK, EEA, and European markets.
We provide UN38.3 compliance reports, MSDS sheets, and secure packaging to meet international air and ocean transit safety regulations.
Our engineering team provides technical documentation and mounting designs to help integrate our battery packs into existing vehicle chassis layouts.
For large motorhome brands and caravan suppliers, procurement decisions are built around long-term lifecycle value and consistent quality. LIAO Technology operates as an OEM and ODM partner, assisting clients from initial electrical load analysis to final assembly line integration. Our engineering team helps design systems that fit within your vehicle's physical spaces while meeting electrical and mechanical requirements.
