1. Do not change the charger casually, and do not remove the speed limiter on the controller.
Chargers from different manufacturers generally have specific requirements, so don't change chargers arbitrarily without proper knowledge. If a longer driving range is required, you'll need multiple chargers for charging in different locations. Use a supplementary charger for daytime top-ups and the original charger for nighttime charging. Removing the speed limiter from the controller may increase the vehicle's speed to some extent, but this will reduce both vehicle safety and battery lifespan.
2. Protect the charger.
Most user manuals contain instructions on protecting lithium-ion battery chargers. Many users don't have the habit of reading the manual, often only remembering to look for it after a problem arises, which is often too late. Therefore, reading the manual first is essential. To reduce costs, most chargers nowadays are not designed for high vibration resistance. Therefore, chargers should generally not be placed in the trunk or basket of an electric bicycle. If it is absolutely necessary to move the charger, it should be properly wrapped in foam to prevent vibration and bumps.
3. Charge it every day.
Even if you don't need a long driving range and can use it for 2 to 3 days on a single charge, it is still recommended that you charge it every day. This keeps the lithium-ion battery in a shallow cycle state, which will extend the life of the electric vehicle's lithium-ion battery.
4. Charge in a timely manner
After an electric vehicle battery discharges, a sulfation process begins, with noticeable sulfation appearing after about 12 hours. Timely charging can remove minor sulfation. If not charged promptly, these sulfide crystals will accumulate and gradually form larger crystals. Ordinary chargers are ineffective against these larger crystals, leading to a gradual decrease in battery capacity and a shortened battery lifespan. Therefore, in addition to daily charging, it's crucial to charge the battery as soon as possible after use to keep it at a fully charged state.
5. Perform deep discharge periodically.
Performing a deep discharge periodically can also help "activate" the battery, slightly increasing its capacity. A common method is to periodically perform a complete discharge. A complete discharge involves riding a bicycle under normal load on a flat surface until the first undervoltage protection signal is triggered. Note that we emphasize the first undervoltage protection signal. After the first undervoltage protection signal, the battery voltage will rise again after a period of time, returning to a non-undervoltage state. Using the battery again at this point can severely damage it. After a complete discharge, fully charge the battery. You will notice an improvement in battery capacity.
