What is an E.bike battery ?
Voltage = Power
The controller & battery really determine the power level of an e.bike; not necessarily just the motor. The controller draws the current. The battery holds the charge (voltage). The broad conclusion is that the higher the voltage, the more powerful the e.bike is
This is why you will notice the power decrease as the battery holds less and less energy during use. A freshly charged battery is in its most “potent” condition.
Watt.Hour = Range
The misconception is that ampere.hour (Ah) is the battery’s duration. Watt Hour (Wh) is in fact the correct measure of size for a battery. In an approximate estimation, you can travel 5-20km for every 100watt-hours, based on an average of mixed levels of power and variation of terrain. Our numbers are real world figures based on customers’ feedback.
Like all things, batteries vary significantly in quality and engineering. Some are just unsafe and scary. Firstly, the battery cells are not made equal. Cells are “farmed” and there are Grade AAA and all the way down to Grade C. The prices vary drastically. Unfortunately, almost all highest grade battery cells are grabbed by car manufacturers in their exclusive deals. Premium E.bike batteries are made from Grade A or A- or B+. Cheap batteries tend to use lower grades of cells that tend to die prematurely or the power is lacklustre. One analogy is that if a restaurant wants the best grade of vegetables from the farms, it has to pay for it.
A battery is in fact made of lots of cells. What determines the battery’s overall duration and safety is how they are connected together. We have spent huge amounts of time researching and visiting battery factories. One can assume that the longer time the production line spends on a single battery, the better & safer the battery will be. More time = better results. We have very strict instructions and protocols with our partner factories as to how our batteries are assembled . We make sure that each and every single battery that we sell is as safe as possible. Sadly, we have seen a great number of unsafe batteries purchased cheaply online.
One common question we get is that should I care about how I am charging the battery. Modern (our) e.bike batteries have a BMS computer board inside to regulate the charging, discharge and prevent over charging and over-use. It also balances the voltage level of each cell. So with our premium BMS. The answer is “no need & just charge it whenever you feel like”.
The charger determines the speed of charging. Fast charging is convenient. But it decreases the longevity of the battery because the “charging” is in fact putting the stress on the battery cells. The faster the charging, the more stress the cells have to bear. If you are not in a huge hurry, a 3 or 5amps charger will do the job just fine.
