Explore our industrial-grade rechargeable packs, engineered for optimal discharge efficiency, longevity, and thermal thresholds.
Deconstructing the global shift from heavy lead-acid configurations to intelligent, power-dense 12.8V LiFePO4 cells.
Within the global battery ecosystem, the nominal voltage of 12.8V represents a critical technological sweet spot. Constructed by grouping four premium Lithium Iron Phosphate (LiFePO4) cells in series (4S configuration), a 12.8V pack behaves as a direct, drop-in replacement for traditional 12V lead-acid, AGM, and gel batteries. However, the operational benefits far exceed outdated chemistries.
Traditional lead-acid batteries degrade rapidly when discharged below 50% Depth of Discharge (DOD). In contrast, 12.8V LiFePO4 technology comfortably delivers up to 100% DOD without compromising structural or electrochemical integrity. This capacity utilization efficiency effectively halves the battery footprint required for complex industrial systems, creating space and weight savings of up to 70%.
On a macro level, decentralized grid networks, remote telecommunications, and maritime transport require reliable, long-cycle energy storage solutions. LIAO's 12.8V systems sit at the intersection of these markets.
Our commitment to rigorous design parameters ensures unmatched safety, cycle durability, and global operational reliability.

How LIAO 12.8V and matched modular setups operate under demanding applications and specialized environments.
Modern golf courses demand quiet operation, high torque output, and zero maintenance. LIAO 12.8V modules can be connected in series (creating 36V or 48V banks) or utilized as direct single modules.
Compared to traditional lead-acid setups, our golf cart solutions reduce weight by 300+ lbs, providing increased acceleration, less turf compaction, and up to 45 miles of runtime on a single charge.
Caravan movers require massive bursts of discharge current to maneuver heavy trailers up steep inclines. The LIAO 12.8V LiFePO4 battery pack handles continuous 1C discharge currents with peak surge currents up to 3C.
Integrated safety relays inside the BMS prevent cell breakdown under high load, operating silently and safely inside small cargo holds without releasing toxic fumes or acidic spills.
Continuous material handling requires fast-charging capability. While lead-acid batteries take 8-10 hours to recharge and need cool-down periods, LIAO LiFePO4 battery packs support 1C charging rates, allowing full replenishment in less than 2 hours.
Operators can charge during short breaks, eliminating the need for spare battery banks and specialized charging bays.
Marine environments expose electronics to high humidity and salt spray. LIAO marine systems feature IP65-IP67 rated enclosures combined with highly efficient cell groups.
No sound pollution or carbon emissions protect delicate marine ecosystems while providing a stable, reliable energy source for trawling motors, onboard electronics, and cabin systems.
Exporting batteries globally requires strict compliance with international safety protocols. Our 12.8V battery lines are certified under the CE directive, ensuring they comply with EU safety, health, and environmental requirements.
This compliance involves meeting the requirements of the Electromagnetic Compatibility Directive (2014/30/EU), the Low Voltage Directive (2014/35/EU), and the RoHS Directive (2011/65/EU). Additionally, our batteries pass UN38.3 safety standards, ensuring safe shipping by air and sea. Each pack undergoes extensive vibration, structural shock, thermal abuse, drop, and short-circuit testing to prevent failure in transit and operation.
As a forward-looking manufacturer, LIAO is actively developing technology to improve energy density, intelligence, and environmental sustainability.

Expert insights addressing key questions on 12.8V LiFePO4 battery specifications, integration, and compliance.
A 12.8V LiFePO4 battery offers significantly higher energy density, a longer cycle life (2800+ cycles at 100% DOD compared to 300-500 cycles for lead-acid), and lower weight. They also support 100% depth of discharge without structural damage, have a much faster charging rate, and maintain stable voltage discharge throughout the cycle.
To receive CE certification, a 12.8V lithium battery pack must comply with the Electromagnetic Compatibility (EMC) Directive (2014/30/EU), the Low Voltage Directive (LVD) (2014/35/EU), and the RoHS directive. It must also pass standard safety tests such as IEC 62619, which covers thermal runaway, overcharging, and mechanical stress safety.
Yes, our 12.8V battery packs can be connected in series or parallel to scale voltage (e.g., 25.6V, 38.4V, or 51.2V systems) or capacity. However, to ensure safety and longevity, the batteries must be identical in age, capacity, and charge state. An integrated BMS is also required to manage balancing.
The built-in BMS monitors individual cell voltages, current, and temperatures. It protects the battery by shutting off the circuit in the event of over-voltage, under-voltage, over-current, short-circuits, or extreme temperatures. It also balances cell voltage to optimize energy efficiency and lifespan.
LIAO cells are rated to operate from -40°C to 85°C. However, for optimal performance and safety, standard charging should be done between 0°C and 45°C, while discharging is supported down to -20°C. For extreme low-temperature applications, we offer customized battery packs with integrated heating elements.
LIAO operates under ISO 9001 quality guidelines. Every batch of cells undergoes capacity sorting, internal resistance testing, and laser welding inspection. Fully assembled packs go through computerized charge-discharge cycles and aging tests before packaging to ensure performance and safety.
