How Far Can a 72v20ah Battery Run?
2 Answers
72v20ah can run about 80 kilometers. 72v20ah indicates that the total voltage of the battery is 72v, using six 12v batteries, with a current of 20ah. The battery is the power source of an electric vehicle, and most electric vehicles are equipped with lead-acid batteries, whose lifespan is calculated based on charge and discharge cycles. The battery is afraid of being undercharged, and keeping it fully charged can extend its lifespan. The correct way to use the charger is: 1. Ensure that the AC power supply matches the charger's input voltage; 2. Ensure that the charger's output voltage matches the battery's rated voltage; 3. First plug in the charger's connector to the battery box, then plug in the AC power plug; 4. The charger should be used indoors, protected from moisture and vibration, and must not be covered during charging. It should be placed in a well-ventilated and heat-dissipating area.
I've ridden electric bikes with similar configurations for several years. The actual range of a 72V 20Ah battery really depends on various factors. I weigh about 70kg, and when riding at a constant speed of 25km/h on flat urban roads, a single charge can last 60 to 70km. The range is better on calm, sunny days, but it can drop by half when going uphill or on windy days. Load is also a key factor—if you carry luggage or ride with a passenger, the range may fall below 50km. Battery aging is another issue; a new battery can go farther, but after a year or two, the capacity declines, reducing the range. It's advisable to check tire pressure before each ride, as properly inflated tires save energy and extend the range. Regular maintenance, like avoiding over-discharging and charging in high temperatures, is also important to preserve battery life. In short, don’t expect it to go too far—it’s suitable for urban commuting, but long trips require planning for charging stops. Tracking each ride’s distance to find patterns is the most reliable approach.
