Can changing from 48v to 60v increase vehicle speed?

Changing from 48v to 60v can increase vehicle speed. Impact on acceleration and range: Changing from 48v to 60v will definitely improve acceleration, but the range will not increase and may instead decrease. With the same battery capacity, a controller with lower power will provide longer range but relatively lower speed. A larger controller will provide higher speed but correspondingly shorter range. Therefore, to increase both speed and range, simply upgrading the controller will only improve speed while reducing range. Precautions for changing from 48v to 60v: It can increase speed by approximately twenty-five percent. The downside is that in summer, the driving range will be reduced. Since the voltage is increased by twenty-five percent, the motor's heat generation will significantly increase, posing a risk of exceeding the Hall sensor's temperature limit. Therefore, in summer, it is not advisable to ride at high speeds exceeding 15 kilometers per hour.
Having been in the car enthusiasts' circle for so many years, I often see discussions about whether upgrading from 48V to 60V can boost speed. The principle is straightforward: increasing battery voltage generally makes the motor spin faster, naturally raising the vehicle speed by about 10% to 20%. However, it's not as simple as swapping the battery—the key lies in whether the controller can handle the 60V load. Many factory controllers are designed for 48V, and modifying them risks burning out, requiring upgraded aftermarket parts. Battery type is also crucial; for instance, switching lead-acid batteries to 60V may pose some risks, while lithium batteries demand enhanced thermal management to prevent short circuits or fires in summer. Though speed increases, the trade-offs are significant: accelerated tire wear, longer braking distances, and potential road legality issues. I recommend consulting a professional tuning shop for a full system evaluation before proceeding—spending a little extra to ensure safety is wiser than sacrificing the vehicle's lifespan for a slight speed gain.
