Can a 72V 20Ah battery be replaced with a 72V 32Ah battery?

[Doreen]

Yes, as long as the voltage does not exceed the original voltage. Relevant information expansion: Introduction to electric vehicles: The main components of an electric vehicle include the frame, motor, battery, and electronic control system. The electronic control system is used to control the entire vehicle's circuit. Without the electronic control system, the electric vehicle cannot operate. The motor is the power source of the electric vehicle, responsible for driving the vehicle forward. The battery is the component used to store electrical energy. Without the battery, the electric vehicle cannot move. The battery is a wearable part on the electric vehicle, and its performance will continuously degrade with the increase in charge and discharge cycles. During charging or discharging, ions in the battery move in the electrolyte, and some ions undergo chemical reactions with the electrolyte during movement. When using the vehicle, it is important to avoid overcharging and overdischarging the battery, and always use an appropriate charger for charging.

With over a decade of experience in repairing electric vehicles, let me briefly address this issue. If the voltage is consistently 72 volts, switching from 20Ah to 32Ah is completely feasible, as both the controller and motor are designed for 72 volts, ensuring electrical compatibility. The key advantage is the increased capacity—a 32Ah battery stores more electricity, significantly improving range and making long-distance travel much more convenient. However, you need to consider the actual installation space, as 32Ah batteries are typically larger and heavier. Measure your frame dimensions to ensure it fits, and you might need to adjust the mounting hardware. Additionally, charging time will increase due to the higher capacity, so it’s best to pair it with a high-current charger for optimal performance. Ensure proper wiring to avoid short circuits—safety first. Overall, the upgrade is quite cost-effective, but consult a professional shop before proceeding to avoid mistakes.

My car owner did this last year, switching from a 72V 20Ah battery to a 32Ah one, and the difference was quite noticeable. With the same voltage, the controller works just fine, and the range has significantly increased. Previously, it would run out of power after 40 kilometers, but now it can last over 60 kilometers. It’s much more convenient for daily commuting with fewer charges. The only downside is that the new battery is a bit larger—I had to measure the rear seat to fit it in—and it’s heavier, making it harder to move. Charging time has roughly doubled, so I got a new charger. The cost is higher, but it’s worth it in the long run with the savings on electricity. I’d recommend checking your car’s manual or visiting a physical store to confirm the dimensions to ensure a smooth installation without affecting other components.

Buddy, I've been riding electric scooters for a long time. Upgrading from 72V 20Ah to 32Ah is awesome! As long as the voltage stays the same, the controller won't have any issues, and the range improvement is insane. Before, I could barely make two laps around the park, but now I can go camping for a whole trip. Just pay attention to the battery size during installation—32Ah batteries are usually wider and heavier, but just measure the space and fit it in. Make sure not to mix up the wires to avoid blowing a fuse. Charging does take a bit longer, but I solved that with a fast charger—no big deal. The benefits are huge: no more range anxiety, and you can go much farther. Just remember to test and fine-tune everything after installation to ensure stability. This upgrade is cost-effective, and I highly recommend you give it a shot—don't hesitate!
