Please remember if the camera does not look like this, it is highly chance its either NEA / PUB / SPF cameras.

Please do take note not all controller have same wiring instruction and etc.

Voltage (V)

Voltage, commonly referred to as electric pressure, is a key measurement of how powerful a controller is. Measured in volts, it tells you the intensity at which the electricity is being pushed through a circuit.

Typically, electric scooter controllers fall into one of these six categories: 36V, 48V, 52V, 60V, 72V, and 84V.

A higher voltage equates to more power, and this results in greater torque, faster acceleration, and higher top speeds.

For example, a high-performance scooter with a large 60V 30Ah battery and powerful 60V 1000W motors will have controllers with a high voltage (60V) to match the rest of the scooter.

Current (A)

Measured in amps, current is the rate at which electricity flows through a circuit. Like voltage, it’s a useful indicator of how powerful a controller is.

Commonly, electric scooter controllers have an amperage that falls in one of these five buckets: 10A, 25A, 30A, 40A, and 50A.

The higher the current, the faster the controller can respond to signals and inputs from a scooter’s electrical parts. The most noticeable impact of this is greater torque, faster acceleration, and higher top speeds.

For example, a high-performance scooter with a large 60V 30Ah battery and powerful 60V 1000W motors will have controllers with a high voltage (60V), but also a high amperage (40A).

Types of Controllers

Square Wave vs Sine Wave

There are two main types of electric scooter controllers: Square Wave and Sine Wave. Both deliver power very differently, with Sine Wave being the preferred option. Fiido usually use Square Wave (YYK) and Ebike use Sine Wave ( ZL ).

Worst day ever, In Singapore, e-scooters will be banned from all footpaths starting Nov 5. Those caught riding on footpaths will be issued warning letters till end-2020. From Jan 1, 2020, offenders will face a fine of up to $2,000, and/or be jailed up to three months. It is the latest restriction on personal mobility devices, after accidents continued to rise in 2019.

Direct Current (DC) voltage refers to the electrical potential or energy provided by a battery or power source in a continuous flow of electrical charge in one direction. In the context of a battery, the DC voltage is the measure of the difference in electric potential between its positive and negative terminals.

mAh stands for milliampere-hour, and Ah stands for ampere-hour. Both are units of measurement used to quantify the capacity of a battery to store electrical energy.

1. **mAh (milliampere-hour):** This unit is commonly used to measure the capacity of small batteries, such as those found in smartphones, portable electronic devices, or smaller power banks. It represents the amount of current the battery can deliver over one hour before it is fully discharged. For example, a battery with a capacity of 2000mAh can deliver 2000 milliamperes (or 2 amperes) of current for one hour before it is fully discharged.

2. **Ah (ampere-hour):** This unit is used to measure the capacity of larger batteries, such as those found in electric vehicles, solar energy storage systems, or industrial applications. It represents the amount of current the battery can deliver over one hour before it is fully discharged. For example, a battery with a capacity of 100Ah can deliver 100 amperes of current for one hour before it is fully discharged.

In summary, both mAh and Ah are used to express the capacity of a battery, with mAh being used for smaller batteries and Ah being used for larger batteries. The higher the mAh or Ah rating, the greater the capacity of the battery to store electrical energy and deliver power.
