Everything you need to know about buying, caring for and what's right for you
When searching for your eBike, you will see several words used in describing the ebike battery. Voltage (v), Amps (Ah) and Watts (Wh).
Voltage (v)
Voltage is the flow of energy, the horsepower that propels the flow of electricity to the motor.
Volts “v” are an international unit for measuring the electrical potential difference, with one volt indicating one joule per coulomb.
The vast majority of electric bikes tend to be either 36V or 48V; nevertheless, consider that the higher the voltage, the more power your bike will have.
Amps (Ah)
Amps refer to a measure of force, and they are ultimately a measurement of the electrical current that is flowing from the battery; in turn, the Amp-hour rating refers to the battery’s capacity (see next item for more details).
Watts (Wh)
If voltage is the flow of energy and amps are the measure of the force, then watts (Wh) are a combination of the two.
Capacity is measured in watt-hours (Wh). To do the math, a Wh is equal to the value of the Amp-hours (Ah) of the battery, multiplied by the Volt (v); for example, a typical 36V, 10Ah battery has 360Wh.
We want to be clear that whilst this can indicate the range you are likely to get, it refers to a continuous power outage.
Charge Cycles
This is one that isn't usually listed but something you pay attention to and ask about. Charge cycles are the number of times your can fully charge your ebike battery. Most brand names and mid to high tier bikes will offer 600 to 1000 charge cycles. More value brand bikes may only offer 300 to 600 charge cycles.
Brand
Brand can be important but isnt a requirement. Most people prefer to go with a brand you know and trust and if the ebike manufacturer uses a trusted brand, they will state it. Most will be made by LG or Samsung.
How to Charge
Last thing to know is how to charge your battery. It is always recommended to take the battery out of the bike and charge it in your house.
Now how it is charged after that, always check with your bike manufacturer to find out when you should charge it (eg: when at 20% left), how long it should charge, to what percentage and so on.
