Implementing internal heat-film architectures to facilitate safe sub-zero lithium charging. Expanding our wide-temperature electrolyte formulations to maintain system capacities at -40 ℃.
Collaborating with clean energy laboratories to formulate semi-solid state LiFePO4 cathodes, aimed at increasing volumetric energy densities to 210 Wh/kg while maintaining standard thermal safety characteristics.
Standardizing local predictive health analytics. Developing embedded machine learning models within local BMS platforms to forecast battery health and cell degradation curves.
Delivering reliable, clean power systems across industrial, marine, and mobile sectors.
Our custom 12V and high-voltage series LiFePO4 battery modules maintain consistent power output across changing golf course topologies, steep inclines, and variable temperatures. They act as drop-in lead-acid replacements, lowering weight and increasing operational range.
LIAO deep-cycle lithium solutions run caravan movers efficiently without generating emission or acoustic pollution. Our battery chemistry is designed to withstand high startup surge currents, helping campers move heavy platforms with minimal strain.
For short-distance logistics, automated guided vehicles (AGVs), and electric forklifts, our robust cells lower battery maintenance requirements. The fast-charging capability of LIAO LiFePO4 reduces vehicle downtime and helps control operational labor costs.
Marine environments require high vibration resistance and water protection. LIAO marine battery packs offer high structural resilience and are designed to avoid thermal runaway. They supply reliable backup and propulsion power without environmental risk.

LIAO maintains strict quality records and holds patents to support international compliance verification.
A guide for sourcing officers verifying battery manufacturers.
Purchasing custom lithium iron phosphate battery packs requires verifying manufacturing and safety standards. To help procurement teams evaluate suppliers, LIAO structures its compliance guidelines around three areas:
Stable multi-cell packs require consistent individual cell parameters. LIAO performs automated capacity sorting and internal resistance screening, matching cell configurations within small tolerances (<10mV and <0.5mΩ) to prevent early pack degradation.
Industrial batteries must communicate with host system controllers. LIAO's BMS systems support CANbus, RS485, and Modbus networks, allowing engineers to monitor cell voltages and temperatures directly from system control interfaces.
UN38.3, MSDS, and relevant shipping certificates are required for international transport of Class 9 Dangerous Goods. LIAO provides complete shipping documentation to help verify transport safety at global ports.
Common questions from buyers regarding our custom 12V LiFePO4 battery manufacturing.
Our standard prototype timeline ranges from 15 to 30 days. This includes CAD mechanical layout design, BMS firmware adjustments, thermal management testing, and initial capacity matching. Production volume delivery timelines depend on raw material availability and target order volumes.
We use automated sorting systems to verify internal resistance and voltage match across all cells before packing. The integrated smart BMS provides over-voltage, under-voltage, and over-current protection, and conducts active balancing to maintain cells within stable voltage parameters.
LIAO's low-temperature cells are designed to discharge down to -40 ℃. For charging under sub-zero conditions, we can integrate internal thermo-heaters controlled by the BMS to warm the cells to safe charging temperatures, preventing lithium plating.
LIAO's manufacturing facilities are certified under ISO 9001, ISO 14001, and ISO 18001/45001. Our battery products hold test certificates and approvals including CE, UN38.3, and MSDS, helping to meet regional import regulations.
