Advanced Power Supply
What Is a Power Battery?
A power battery is a lithium-ion pack optimized for high-current output rather than just energy capacity. It emphasizes fast charge/discharge and high peak power with robust safety. In practice, power batteries are used as the drive batteries in e-bikes, industrial equipment and power tools. Unlike “energy” batteries (which focus on total capacity and long runtimes), power batteries deliver energy more quickly and can sustain very high discharge rates. In other words, they provide bursts of power exactly when robots, forklifts, drones and other highdrain systems need it. LiFePO4 chemistry is common here because it safely handles heavy power loads and recharges quickly, enabling continuous operation in demanding environments.
Custom Product Categories
Voltage-Based Packs:
We offer 12V, 24V, 36V and 48V LiFePO4 battery packs, fully customizable for your needs. For example, 12V power battery packs are designed as drop-in upgrades for lead-acid in golf carts, marine vessels and RV electrical systems. Higher-voltage packs (24V/36V/48V) suit larger vehicles and equipment (e.g. industrial machines, solar energy storage, off-grid systems).
Application-Specific Packs:
We design batteries for specific uses and industries. Our LiFePO4 packs power AGVs, UGVs, UAVs and industrial robots, as well as drones, golf carts, boats/marine equipment, ATVs/UTVs, electric motorcycles, RVs and more. Each pack is tailored (voltage, capacity, shape, BMS settings) to meet the exact requirements of the target application.
Large Power: High-Cycle LiFePO4 Power Batteries & Lead-Acid Replacements
Why Choose Large Power for Power Batteries and Lead-Acid Replacement: Large Power is a leading LiFePO4 battery manufacturer and supplier with over 20 years of experience in custom power solutions. We build power batteries with extremely high cycle life – typically 4,000–6,000+ cycles at 80% depth-of-discharge (roughly a 10year lifespan) – which is 5–10× longer than comparable lead-acid batteries. Our packs dropin replace 12V leadacid systems in applications like golf carts, marine craft and RVs, running down to 100% depth-of-discharge without damage. Certifications and safety are built in: our LiFePO4 batteries meet global standards (UL, CE, RoHS, IEC 62133, UL2054, UL1642, etc.).
- High Cycle Life:LiFePO4 cells deliver ~4,000–6,000 cycles (10+ year life), far exceeding leadacid.
- Lead-Acid Replacement:Drop-in LiFePO4 packs outlast and outperform lead-acid by 5–10×. For example, a 12V 100Ah LiFePO4 pack weighs ~9 kg versus ~29 kg for lead-acid, and can safely discharge fully.
- Lightweight & Safe:Our LiFePO4 packs contain no corrosive acid or fumes, and typically weigh ~30% of the equivalent lead-acid system.
- Global Certifications:We support UL, CE, RoHS, REACH and other approvals to match your market requirements.
- Proven Track Record:Over 9,000 custom LiFePO4 battery packs delivered worldwide, powering applications in robotics, marine, telecoms, security, mining and more.
This deep expertise ensures our LiFePO4 power batteries are reliable and tailored to demanding applications.
Large Power’s standard batteries serve a range of B2B markets, including:
- Robotics & Automation OEMs:Manufactures of AGVs, UGVs, UAVs, autonomous robots and industrial automation systems.
- Mobility & Marine OEMs:Makers of electric vehicles (e-scooters, golf carts, e-motorcycles, ATVs, UTVs), marine craft and RVs.
- System Integrators & Distributors:Companies specializing in industrial power systems, renewable energy storage, backup power or mobility solutions in the above sectors.
- Flexible Production:We serve both large enterprises and smaller innovators. Our production lines scale from single-unit prototypes up to high-volume manufacturing, and we support flexible MOQs. With a global supply chain, we ensure reliable logistics and on-time delivery for OEMs and distributors worldwide.
Where Is an Advanced Power Supply Used? Typical Application Scenarios
Battery packs for AGVs, UGVs, UAVs and other robots. LiFePO4 power batteries deliver very high output (fast discharge) for heavy lifting and rapid motion. Our packs handle fast charge/discharge cycles and extreme duty, ensuring consistent, long-lasting performance in factories and warehouses.
Golf carts, marine craft, RV power systems and electric motorcycles. Our LiFePO4 packs provide 5–10× the cycle life of lead-acid and can safely be discharged to 100%. That means longer runtimes, much less maintenance (no watering), and lighter systems. They make ideal drop-in replacements in any application that traditionally used a 12V/24V lead-acid battery.
High-voltage packs for ATVs, UTVs, electric go-karts and other new-market EVs. We supply rugged LiFePO4 battery packs optimized for off-road and utility vehicle use, with custom BMS logic and form factors to handle shock, vibration and outdoor conditions.
