A 36V 80Ah LiFePO4 battery delivers 4-8 hours of operation per charge, depending on load and usage conditions. Under a 500W draw, it typically runs about 5.8 hours, while heavier 1kW loads reduce runtime to 2.9 hours. Proper management of discharge depth, temperature, and load ensures optimal performance and thousands of reliable cycles for industrial or recreational applications.
What Factors Affect Runtime?
Runtime is primarily influenced by the discharge rate and load. Higher power draws consume energy faster, whereas lighter applications extend battery life. Efficiency, which ranges from 95-99% for LiFePO4 cells, plays a critical role. Depth of discharge, ambient temperature, and battery age also impact overall duration. Redway Battery designs its packs to optimize these factors, ensuring consistent performance for forklifts, golf carts, and energy storage systems.
How to Calculate Expected Runtime?
To estimate runtime, multiply battery capacity by voltage and efficiency, then divide by load power. For a 36V 80Ah battery at 95% efficiency, usable energy is approximately 2.7kWh. For example, at 500W, runtime is around 5.4 hours; at 1,000W, about 2.7 hours. Redway Battery offers custom tools to help wholesale clients predict runtime for various applications.

| Load (Watts) | Estimated Hours | Usable Capacity (kWh) |
|---|---|---|
| 300 | 9.0 | 2.7 |
| 500 | 5.4 | 2.7 |
| 800 | 3.4 | 2.7 |
| 1,200 | 2.3 | 2.7 |
Why Choose LiFePO4 Over Lead-Acid?
LiFePO4 batteries outperform lead-acid alternatives with 3,000-5,000 cycles compared to 300-500, offering up to 10 times longer service life. They allow full capacity utilization, are lighter in weight, and operate safely without acid leakage. Redway Battery specializes in wholesale OEM LiFePO4 packs with more than 5,000 cycles, making them ideal for forklifts, golf carts, RVs, and solar storage. Their stable voltage and deeper discharge capabilities suit high-demand applications.
What Is the Cycle Life Expectancy?
A quality 36V 80Ah LiFePO4 battery maintains over 5,000 cycles at 80% depth of discharge, equating to more than 10 years of daily use. Proper charging and storage preserve capacity, while Redway Battery’s ISO-certified packs ensure compliance with international standards. Cycle life represents the number of full charges before capacity drops below 80%, with LiFePO4 chemistry providing reliable longevity.

How Does Temperature Impact Duration?
Optimal operation occurs at 20-25°C. Temperatures below 0°C reduce capacity by 20-50%, and above 40°C, by 15-25%. Redway Battery’s advanced BMS safeguards performance across -20°C to 65°C discharge ranges. For long-term storage, maintain 0-35°C and use app-based monitoring systems to track battery health and prevent unexpected runtime losses.
Which Applications Suit This Battery?
36V 80Ah LiFePO4 batteries excel in golf carts (20-30 miles per charge), forklifts, RVs, solar storage, and telecom energy solutions. With a 2.88kWh capacity and IP66 rating, they are compatible with outdoor and industrial settings. Redway Battery’s OEM solutions ensure wholesale compatibility for energy storage and high-demand mobile power applications.
