How many kilometers can 4 12V batteries run?
2 Answers
An electric vehicle with four batteries can typically travel approximately 80 kilometers. The maximum range of an electric vehicle depends on the battery capacity. Regular Charging: Generally, batteries start discharging as soon as they leave the factory. If left unused for one or two months, the battery may fully discharge. Prolonged inactivity can degrade battery performance and reduce range. Therefore, even when not in use, it is advisable to charge the battery every half a month to a month. Fully Charge Before Use: Many owners often forget to charge the battery after use, leading to reliance on fast charging when in urgent need. While a single fast charge may not have a significant impact, frequent use can cause the battery to develop a "memory effect," making it unable to hold a full charge in the future. This affects both the range and the battery's lifespan. Simply put, a fully charged standard battery can travel about 30 kilometers, whereas frequent fast charging may reduce this to just over 10 kilometers. Regular use of fast charging can impair battery performance and shorten its lifespan.
Last time I replaced four 12V batteries for my small electric scooter, and it could run nearly 50 kilometers on a full charge. It depends on your battery capacity—mine is 20Ah, which is a common specification. Also, vehicle weight and road conditions have a big impact. For example, with my 70kg weight, riding on flat roads saves much more power than carrying a passenger uphill. In cold winter temperatures, battery efficiency drops, and the range might be reduced by 20%. My personal advice is not to drain the battery completely before charging; it's best to recharge when about 30% is left for optimal battery maintenance. This way, a set of batteries can last over two years. Frequent riders should consider choosing higher-capacity batteries.
