Wholesale Light Weight 12v 200ah Lithium Ion Battery Manufacturer & Factory

High-Capacity LiFePO4 Battery Engineering, Professional Custom Designs, and Certified Global Supply for Industrial, Solar, and EV Applications

The global battery landscape is experiencing a decisive structural transition. Heavy, maintenance-intensive lead-acid batteries are rapidly being phased out. Modern commercial and consumer sectors require lightweight, energy-dense power storage solutions. At the epicenter of this shifting market demand is the 12V 200Ah Lithium Iron Phosphate (LiFePO4) battery.

By leveraging advanced Prismatic Cell architectures, manufacturers are now engineering energy solutions that offer twice the usable capacity of traditional AGM/Lead-Acid counterparts at less than half the physical weight. This critical optimization opens up vast application profiles—ranging from marine vessels, camper vans, RV caravans, and high-altitude solar energy storage grids to industrial applications where load optimization directly correlates to operational efficiency and fuel savings.

Global distribution requires meeting safety and shipping regulations. Hangzhou LIAO batteries are certified for international market entry, including CE, UN38.3, and MSDS safety protocols, ensuring safe transit via sea or air freight.

ISO Certificates, Patent Profiles, and Safety Approvals

This technical and legal compliance simplifies importing into highly regulated markets, including the European Union, North America, Japan, and Australia.

6. Technical Roadmap & Future Battery Chemistry Outlook

The battery industry is moving toward higher energy densities, fast-charging integration, and smart monitoring. Our R&D team works to continuously improve performance by developing ultra-thin separators and stable cathode formulas that maintain cell structure under high currents.

In addition, we are integrating Bluetooth, CANbus, and RS485 communication protocols into our BMS modules. This allows operators to monitor cell voltages, temperature profiles, and state of charge (SoC) in real time via central system dashboards or mobile apps, reducing maintenance costs.

Technical FAQ & Sourcing Advisory

Key technical information for project engineers and procurement managers.

What are the weight advantages of a lightweight 12V 200Ah LiFePO4 battery compared to lead-acid?
A standard 12V 200Ah lead-acid or AGM battery typically weighs between 55kg to 65kg. In contrast, a LIAO 12V 200Ah LiFePO4 pack weighs between 20kg to 24kg, depending on the casing and BMS. This represents a weight reduction of over 60%, improving fuel economy and ease of installation.
How does the extreme temperature performance (-40°C to 85°C) work in cold climates?
LIAO's low-temperature battery chemistry is formulated to resist electrolyte freezing and high internal resistance in sub-zero environments. While typical lithium batteries see sharp drop-offs below 0°C, our low-temperature series maintains stable discharge characteristics down to -40°C.
Can these 12V 200Ah packs be connected in series or parallel for larger systems?
Yes. Our 12V 200Ah packs can be wired in series (up to 48V configuration) or in parallel to scale capacity, provided they are matched in charge level. The integrated BMS balances the cells and prevents overvoltage or overcurrent.
What safety testing protocols are used during factory production?
Every production run undergoes strict safety tests, including cell capacity matching, high-voltage insulation tests, vibration simulation, thermal cycling, and nail penetration tests to verify safety under extreme conditions.
Do you support OEM and ODM custom battery designs?
Yes. We offer full OEM and ODM services, including customized case sizing, custom BMS profiles, branded shell colors, and specialized connection ports to match your product specs.
