E bike battery selection

How to Select an E Bike Battery?

Although electric bikes have been recognized for a long time, they are getting more popular in the last few yrs, and the use of an e bike battery is growing. What makes so many people run after them? It is quite simple. An e bike is a method of transport, which integrates the most effective functions of scooters and also bikes, it's environmentally friendly, assists to take care of the problem, assists to stay clear of traffic, makes it simpler to ride through bothersome hills, and does not make any type of heavy noise.

The base of the e bike is the electric motor and certainly the e bike battery, which is what we are going to mainly discuss. As in the title, we'll address the concern-- how to choose an e bike battery? Relying on whether you change the e bike battery or convert a conventional bike to an electrical one, after reading this write-up you need to understand every little thing about selecting the right battery version.

We would like to explain that this short article only relates to e bikes of the "pedelec" type, meaning those with electrical propulsion turned on by pressing the pedals. It's normally utilized e bike modern technology. The write-up does NOT relate to designs geared up with manual drive (cuff).

Step-By-Step Procedure To Select an E Bike Battery

1. Voltage

The e bike motors are factory adapted to the particular battery voltage they operate with, so our task is just to match one to the other one. Unquestionably, if the motor controller permits it, in a few cases it is possible to operate with e.g., 36 V electric motor and 48V battery, however, this is not an advised arrangement and relates to non-standard e bike versions, so we discuss this only curiously.

2. Input in the e bike, which is the kind of socket

The concern is quite clear. Please focus on what kind of input is in your e bike and pick a battery e bike with the relevant version. One of the most usual kinds of connections is 4-pin.

3. The power of the bike controller and the engine

We have to bear in mind that the more powerful the engine, the much better the acceleration, the more assistance on the ascent and subsequently, the much quicker the battery discharge. This concern is not much trouble if we purchased a ready-made, legally compliant e bike. When we talk about consumer bikes, we're, in some places, restricted by regulations to 250 W as well as 25 km/h, because such optimal power can be offered by e bikes. If we have currently gotten to 25 km/h, the engine might not be able to give more than 250 W and also will certainly not sustain the drive. Understanding that only in such ranges, the engine will operate, it is simple for us to evaluate which e bike battery we require.

The scenario is slightly different in case we have a custom-made bike model. Naturally, a whole lot depends on the riding style, yet let us not mislead ourselves if we possess a powerful engine, we'll absolutely wish to use its capacities. Recognizing that our e bike will have a high performance, it is worth considering additionally purchasing a bigger battery e bike to be able to get this performance longer. However, let's not forget that when testing the e bike's capabilities, we should not place the battery/engine to severe tests if we do not have some proper protection! The engine won't go out like a combustion engine and some damage might take place.

4. The shape of an e bike battery, attachment, and sizes

We need to respond to the concern: what does our battery resemble as well as where do we place it on our e bike? If we change the e bike battery, it is quite straightforward; we select the shape we had previously. But, if we construct an e bike ourselves, we face a major dilemma. There are lots of sorts of e bike batteries, so below we will talk about the common ones:

Frog batteries: A battery installed under a saddle. This is a somewhat less usual kind, typically on smaller e bikes. It's frequently utilized in folding bikes.

Rear Rack Batteries: Rack battery, installed on the back of an e bike, just behind a saddle. This kind is normally utilized in city e bikes. Because of their location, they have a particular glare.

Silverfish batteries: This is one of the most prominent kinds of batteries for a bicycle, yet the methods of mounting it could be different. Depending on which bike you have, it can be put along with the bottom or back of the frame, or even on a trunk.

Bottle batteries: A kind having a similar shape like Silverfish and various mounting approaches are additionally feasible, however, the so-called bottle mounting is frequently made use of. The name certainly shows the place.

Down Tube Batteries: Practically exclusively for bottle mounting.

5. Capacity We Need

Battery capacity depends mainly on our requirements as well as the role that an e bike needs to play. We need to take into consideration the distance we wish to cover and also whether we will subject our e bike to higher loads, e.g., riding usually on hilly surfaces. When selecting a suitable model, the most crucial aspects are the weight, price, and desired range of the e bike battery.

Batteries for e bikes are based on similar cells like batteries for laptops or various other smartphones, so the range of e bikes could be compared to the functioning time of mobile computers.

If we mainly go through hilly areas, we can deplete the e bike battery after 90 km. Nonetheless, the exact same battery e bike will go out after just 45 km of extensive biking in some other area.

An additional variable is the driving mode. This is the level of assistance to be offered by the engine. E bikes typically have 2 or occasionally 3 modes. We will certainly concentrate on 2; Eco as well as Turbo. The Eco setting is created to save power, the support is lowered to raise the range (yet it is quite sufficient to easily climb up hills). On the other hand, turbo mode is focused on making the climb as simple as feasible and also considerably enhancing acceleration. The range in km additionally depends upon the weight of the baggage as well as the user. When riding on an e bike, the engine doesn't work all the time, a lot less at max power, so the distance that is traveled on a single charge can really be a lot longer.

Purchasing the Battery

If we already understand everything about the parameters and kind of battery and also have decided what capacity the battery e bike requires, let's look for it! You can explore a wide variety of e bike batteries in our store.
