Our Advanced Technical Capabilities

  • Smart BMS Configurations: Support CANbus, Modbus, RS485, and RS232 protocols to communicate with motor controllers and smart chargers.
  • Prismatic Cell Sorting: Strict capacity, internal resistance, and voltage grading to ensure perfect cell matching before pack building.
  • Dynamic Thermal Management: Enclosure structures with heat dissipation pads and thermal monitoring to guard against hot spots.
  • Laser Welding Integrity: Fully automated laser welding lines create low-resistance connections, preventing high current failure.

We source high-grade prismatic cells, partnering with tier-one suppliers like CATL and EVE, and manufacturing custom arrays of 12V, 24V, 36V, 48V, and 96V systems tailored to client requirements.

China Factory Supply Chain & Production Process Tour

China commands over 70% of the world's lithium supply chain, from raw lithium salts and anode/cathode refinement to cell fabrication. LIAO integrates these upstream benefits to pass on cost savings and high material purity to global buyers.

Lithium-Ion Battery Industry Q&A (FAQ)

1. What makes LIAO LiFePO4 battery packs safer than standard NMC lithium-ion batteries?
Lithium Iron Phosphate (LiFePO4) chemistry features a strong covalent bond between iron, phosphorus, and oxygen atoms. This structure remains highly stable even at elevated temperatures, preventing the release of free oxygen. As a result, our cells do not support thermal runaway or explode under structural impact, short circuit, or nail penetration testing.
2. Can LIAO customize battery packs for high-voltage and high-current industrial vehicles?
Yes. We design and build custom systems like our 96V 200Ah battery pack, which is engineered for heavy machinery, forklifts, AGVs, and excavators. These packs include a smart BMS configured for high continuous discharge current, active balancing, and communication interfaces like CANbus or RS485.
3. How does the low-temperature performance of LIAO batteries compare to lead-acid alternatives?
While typical lead-acid batteries lose up to 50% of their effective capacity at sub-zero temperatures, LIAO batteries are engineered to operate down to -40℃ and up to 85℃. This reliability makes our packs suitable for cold-storage facilities, telecom backup stations, and high-altitude off-grid solar systems.
4. Do your battery packs support drop-in replacement for traditional lead-acid systems?
Yes, our 12V 100Ah, 12V 200Ah, and 24V packs are designed to fit standard lead-acid footprints. They feature similar nominal terminal voltages but deliver significantly lower weight, double the usable capacity (100% DOD compared to 50% DOD for lead-acid), and a cycle life exceeding 2800 cycles.
5. What certifications are provided for export customs clearance?
Hangzhou LIAO Technology operates under strict quality standards. Our manufacturing processes are certified to ISO 9001, ISO 14001, and ISO 18001. Additionally, our battery packs are supplied with UN38.3 test summaries, MSDS sheets, CE declarations, and IEC62619 reports to ensure worry-free ocean and air shipping.
6. What is LIAO's minimum order quantity (MOQ) for custom OEM/ODM battery packs?
Our MOQ varies depending on the battery size and capacity. For small custom assemblies, we offer low MOQ options to support engineering prototyping. For larger systems (such as high-voltage storage or specialized vehicle batteries), our engineering team works directly with clients to finalize the design before launching volume production.
7. How does a Smart BMS protect the battery during operation?
The integrated Smart BMS monitors each cell's voltage, current, and temperature in real time. It protects the pack by preventing over-charging, over-discharging, over-current, and short circuits. It also balances cell voltages during the charge cycle to maximize the pack's overall capacity and service life.
8. What is the typical lead time for custom battery prototypes?
Standard prototype designs take about 2 to 3 weeks. This includes mechanical enclosure rendering, BMS programming, cell matching, and full capacity cycle testing. Volume production orders are scheduled based on materials availability and order size, typically taking 30 to 45 days.
