How many kilometers can a 48V20A battery run?
3 Answers
48V20A battery can run 68.5 kilometers. Factors affecting the range of electric vehicles: Controller power, tires, vehicle weight, road conditions, and riding habits all have an impact. Even for the same vehicle, the range varies under different riding conditions. Therefore, in such cases, only a rough comprehensive estimate can be calculated. Charging precautions: The shallower the depth of discharge each time the battery is used, the longer the battery's lifespan will be. Therefore, regardless of the capacity of the battery pack, users should develop the good habit of charging as they use it. When the battery needs to be stored for a long time, it must be fully charged first and replenished periodically, generally once every 1-2 months.
As an electric bike shop owner, I hear this question seven or eight times a day! The actual range of a 48V20Ah battery pack is affected by too many factors: lead-acid batteries can run 40-55 km at normal temperature, while lithium batteries can run about 20% more. The controller you use is crucial—a 500W motor and an 800W motor can differ by more than ten kilometers! Load capacity is also critical. We tested in my shop: a 70kg person riding alone versus carrying 50kg of rice directly reduces the range by 30%. And don’t forget to check tire pressure—underinflated tires can increase battery consumption by 15%. I recommend gentle starts and fewer brakes. In summer, running 50 km is no problem, but in winter, be content with an 80% range!
Just tested this spec battery last week with a tester. Under ideal conditions - flat road, no wind, 65kg rider maintaining 25km/h constant speed on a new national standard e-bike, the lead-acid battery delivered exactly 46km before complete shutdown. But reality is never this perfect! Headwinds instantly slash 10km off the range, and climbing an overpass consumes extra 5% charge. Modified bikes fare even worse - a friend just complained his non-compliant e-moped barely manages 30km due to its power-hungry 1200W motor. The worst offenders are cheap chargers - just three overcharge/discharge cycles can make capacity plummet, wiping out any savings from buying budget batteries with premature replacements!
