Introduction
In customized battery solutions, manufacturers use a compact naming convention — 24400, 48100, 72280 — to specify voltage and capacity in one code. Understanding these codes helps procurement teams and OEM engineers quickly identify the right ultra-large power lithium battery for electric vehicles, energy storage systems, industrial equipment, and marine applications. This guide decodes each specification and explains its best-fit scenarios.
How the Ultra-Large Power Lithium Battery Code Works
The naming convention follows a simple rule: Voltage × 1000 + Capacity (Ah) = Code. For example, 24V × 1000 + 400Ah = 24400. This system lets buyers instantly decode any ultra-large power lithium battery’s nominal voltage and capacity without digging through spec sheets.
| Code | Voltage | Capacity | Energy (kWh) | Common Cell Config |
| 24400 | 24V | 400Ah | 9.6 | 8S |
| 48100 | 48V | 100Ah | 4.8 | 16S |
| 72280 | 72V | 280Ah | 20.16 | 24S |

24400 Code — 24V 400Ah Ultra-Large Power Lithium Battery
24400 refers to a 24V 400Ah pack delivering 9.6 kWh of energy. This ultra-large power lithium battery is ideal for scenarios that require large current output and long working time at a moderate voltage platform — electric scooters, golf carts, small forklifts, residential solar energy storage systems, and off-grid telecom stations. With its ultra-large capacity, the 24400 battery provides continuous and stable power output for 4+ hours at a 2.4 kW average load, making it a practical choice where extended runtime outweighs peak power demands.
48100 Code — 48V 100Ah Ultra-Large Power Lithium Battery
48100 designates a 48V 100Ah pack with 4.8 kWh total energy. The 48V platform has become an industry standard for telecom base stations, mid-size forklifts, data center UPS systems, and commercial energy storage. Its moderate voltage output and proven reliability give 48100 batteries wide application demand — particularly where existing 48V infrastructure (inverters, motor controllers) can be leveraged without redesign. For buyers evaluating TCO, this ultra-large power lithium battery offers a cost-effective entry point with 3,000–6,000+ cycle life.
72280 Code — 72V 280Ah Ultra-Large Power Lithium Battery
72280 represents a 72V 280Ah pack delivering 20.16 kWh — the highest energy among the three common codes. This ultra-large power lithium battery suits scenarios demanding both high voltage and large capacity output: electric buses, ship propulsion systems, mining vehicles, special-purpose vehicles, and large-scale ESS installations. With high voltage and ultra-large capacity combined, the 72280 battery meets the needs of these fields for sustained high power output and long working time, supporting heavy loads that lower-voltage packs cannot handle efficiently.

Key Factors Before Choosing Your Ultra-Large Power Lithium Battery
- Match voltage to your system — 24V for light EVs, 48V for telecom/UPS, 72V for heavy EVs and marine.
- Calculate runtime — Divide kWh by your average power draw. 24400 (9.6 kWh) at 2 kW ≈ 4.8 hours.
- Check certifications — All packs must comply with UN38.3 for transport. For industrial safety, refer to IEC 62619 and Battery University for design guidance.
- BMS integration — Define CAN/RS485 communication protocol and protection thresholds.
Conclusion
Understanding the meaning and application scenarios of these codes — 24400 (24V 400Ah), 48100 (48V 100Ah), and 72280 (72V 280Ah) — helps manufacturers and users choose the right ultra-large power lithium battery for their needs, improving energy efficiency and performance across industries.
