How Far Can a 7280 Lithium Battery Run?

[Mitch]

7280 lithium battery can run 200 kilometers at a speed below 60. The following are specific details about lithium batteries: Background: A lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and non-aqueous electrolyte solution, which is different from rechargeable lithium-ion batteries and lithium-ion polymer batteries. The inventor of the lithium battery is Edison. Due to the highly reactive chemical properties of lithium metal, the processing, storage, and use of lithium metal require very high environmental conditions. Classification: Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium metal batteries are usually non-rechargeable and contain metallic lithium. Lithium-ion batteries do not contain metallic lithium and are rechargeable.

I've researched batteries for quite a while. A lithium battery like 7280 typically refers to a 72V 80Ah battery pack with a total capacity of about 5.76kWh. The range mainly depends on how you use it and the vehicle configuration. For electric vehicles, on average, you can travel 40-60 kilometers per kWh, so theoretically, the maximum range is around 240 kilometers. However, actual range is greatly affected by speed: driving at full speed on highways may consume power quickly, reducing the range to about 150 kilometers; slow riding in urban areas with medium load can still maintain a range of 180 kilometers. Battery temperature is also crucial—low temperatures in winter can cause voltage drops and reduce range by 20%, while overheating in summer can accelerate aging. Avoid frequently discharging below 20% depth, as it can damage battery lifespan. Regular maintenance is essential, including checking for electrode corrosion and loose connections. Use the original slow charger for charging and minimize fast charging to avoid internal wear. Overall, with proper maintenance, it can last for three to five years or more.

I've been riding an electric bike for almost ten years with a battery like 72V80Ah, and the range depends on usage habits. My daily commute is 20 kilometers one way, 40 kilometers round trip, and charging twice a week is enough. On weekends, I take my kids out for fun, and even after an 80-kilometer trip, the battery remains stable. To maximize range, pay attention to details: avoid always riding at full speed—keeping it at 60% is more energy-efficient; maintain proper tire pressure to reduce wind resistance; minimize sudden braking and acceleration; in winter, use a battery cover or park indoors to retain warmth. Now, a single charge easily gets me 150-180 kilometers, adjusted based on road conditions. For maintenance, I visit a professional shop every six months to check voltage, and I avoid waiting until the battery is completely drained before charging. After two and a half years of use, there's no noticeable drop in range. In short, understand your bike's behavior, and don't worry about distance.

Safety first with lithium batteries. The 7280 model not running far could be a sign of aging. A new car can typically run over 200 kilometers, but improper use may shorten its lifespan or pose risks. Over-discharging can easily cause internal short circuits, overheating, or even fires; a sudden drop in range in cold temperatures is normal, but avoid forcibly charging to the upper limit. If you notice the range suddenly dropping from 180 kilometers to 100 kilometers, check the battery for swelling or unusual odors. Regularly inspect the connection wires and casing for damage. Always charge in a dry, well-ventilated environment and avoid modifying the circuit. I once experienced a breakdown due to insufficient battery power and have since made it a habit to charge at 50%. How far you can go isn't as important as maintaining a healthy state to extend its lifespan.
