Electric Bicycle Battery Official Guide

Everyone is eager to own a perfect electric bicycle. It makes it easy for you to go downhill, tow you, your equipment, and let you ride effortlessly. As with any equipment you carry with you, you need to know as much as possible about your electric bike. This is what we are here to help you. Our special focus on this electric bike blog will be on the battery.
Electric bicycle batteries are the source of life for bicycles. Without a battery, it is just a complicated bicycle, dragged down by unnecessary gears. It also happens to determine how far your bike can travel under the power of the motor and how fast it can travel.

WHAT EXACTLY IS AN EBIKE BATTERY?

The battery on an electric bicycle can accomplish both of these tasks and is also a decisive part of performance. The size of the battery is directly related to the power of the bicycle.
do not worry. Although batteries have multiple functions and are different from traditional lead-acid batteries, they are not difficult to understand.
The difference between electric bicycle batteries and traditional car batteries is that they are not just a large battery. Quite the opposite. They consist of multiple 18650 batteries.
Yes, these batteries are the same as those used in your rechargeable flashlight. The difference is that they are connected in series to serve as a single unit.
In addition, the balancer inside the battery is also used to ensure that the charge and load on the battery are equal to promote longer life and better use of stored energy.
A further difference between these and car batteries is that they rely on lithium instead of lead. The use of lithium does increase the price a bit, but it brings several advantages, that is, these are almost maintenance-free.
The first thing you need to pay attention to is to fully discharge the battery, because doing so will shorten the life of the battery. Fortunately, the onboard system is in place to avoid this situation.
They work by cutting off battery power when the battery is too low, leaving only enough power to prevent damage to the battery.
However, not all electric bicycle batteries are made the same way, which is why you need to learn more about these relatively expensive components before investing in them.

HOW LONG DO EBIKE BATTERIES LAST?

Another advantage that lithium batteries have over their counterparts is that they can supply a superior number of cycles. The cycle of a battery is essentially the number of charges it can provide in its lifetime. If a battery can offer 300 cycles, you can get 300 charges.
Three hundred cycles are about average for a lead-acid battery. Nickle batteries can supply 500, and that’s a significant step up. On the other hand, lithium batteries can provide an average of 1,000 cycles before needing to be replaced.
So long as you practice proper care, eBike batteries can supply around three years of use to the average hunter.

WHAT’S THE TYPICAL RANGE OF EBIKES?

The maximum range is generally based on a ride that takes place under perfect conditions. Riders can usually achieve that maximum range by limiting the use of the battery. Furthermore, there’s no consideration of rider and gear weight.
In most cases, those numbers come from riders who aren’t hauling gear. More weight takes more power to overcome, and you can expect the actual range to be a bit lower when you start piling gear on and hopping on your electric bike.

HOW MUCH DOES SPEED AFFECT THE LONGEVITY OF MY BATTERY?

There is no internal combustion engine on an eBike. There’s a motor. They aren’t the same, even if the terms motor and engine are used interchangeably.
An engine runs on fuel. So, even if it’s dependent on the battery to supply small amounts of electricity, burning fuel creates motion.
That isn’t the case with a motor as they are entirely reliant on electricity. For all intents and purposes, the battery is your fuel source on electric hunting bikes.
Just like an engine consumes more fuel to reach higher speeds, a motor draws more energy from the battery. As a result, driving faster drains the charge more rapidly than you would at moderate speeds.

HOW MUCH IS A REPLACEMENT?

You can find cheap e-bike batteries from aftermarket suppliers for around $250. However, we warn you not to use this option. Those cheap batteries are usually inferior in quality and cannot fulfill many of the promises they have made.
Going to the bicycle manufacturer is usually the best option. Their price may be four times the price, but their quality is much better than many low-priced suppliers on the Internet.
Of course, there are exceptions to this concept. You can find a decent battery cheaply. We recommend that you talk to experts, especially those who are familiar with your exact model, because their knowledge of the market can help you find a battery that fits your price range.

TECHNICAL ASPECTS EXPLAINED: VOLTS, AMPS, AND WATTS

When you shop for batteries on your own or talk to a specialist, a few key terms are going to appear.

It’s important to know that all of those terms used to describe a battery are essential as they determine whether or not it is compatible with your eBike.

Voltage: The measure of pressure driving electricity through a circuit. Think of this as what causes electricity to move through a circuit. Your electric bicycle is built around this measurement as it determines how much current can be delivered by the battery.
Amps: The amount of electrical charge flowing per second. You can think of this as volume or how much electricity is available in a circuit. They often appear in amp-hours, which simply refers to how many amps can be delivered in one hour.
Watts: Essentially defines the workload, or how much work can be achieved—aka performance. This measurement is found by multiplying volts by amps. This is important because voltage and amps come together to drive components.
Watt Hours: Can be used to calculate the approximate range of a bike. Multiplying amp hours by voltage gives you watt-hours. As a rule of thumb, every 20-watt hours can provide one mile of travel.

CAN’T I JUST ADD A BIGGER BATTERY?

The size of the battery and the specs above correlate with the amount of power it can supply and the range you can obtain. So, shouldn’t you just add a bigger battery? If a little is good, a lot is better. Right?

Not exactly. You might be able to upgrade the battery to a small degree. However, the components of the bike and the batteries match one another.

While your motor is always dependent on amps and voltage, the electronic parts can only handle so much, and going too big will cause severe damage.

It’s not as simple as buying a cheaper bike and combining it with a more capable battery. If you want more range, more power, or a higher top speed, simply invest in the better bike in the first place.

HOW ABOUT RECHARGING? ANY ADVICE?

The major weak point of a lithium battery is that the life of each charge gradually gets shorter each time. When you charge them to 100%, the system shuts off.
If you continue to leave it on the charger, as you would if you leave it overnight, that charge will naturally be lower. When it does, the charger kicks back on tops the battery off.
Over several hours, that accumulation of discharges and recharges can harm battery life. The best way to avoid this is simply charging the battery to just under 100% and only charging up when needed.

FINALLY – HOW DO I GET THE MOST OUT OF MY EBIKE BATTERY?

1: KEEP IT CHARGED IN STORAGE
We did say only charge the battery when you need to. However, you don’t want to store the battery with any less than 40% of a charge.
During the off-season, check up on it from time to time to make sure it doesn’t go any lower, as letting it go completely dead for extended periods can cause damage.
2: TAKE IT TO THE EXTREME FROM TIME TO TIME
We’re about to contradict ourselves by telling you that it’s a good idea to let the battery discharge completely and charge it to 100% every 30-40 charges. This helps to monitor the battery’s condition by ensuring everything is functioning correctly while giving you the advantage of utilizing the battery in its entirety.
3: KEEP AWAY FROM WATER
Avoiding deep puddles on an eBike is a must as it’s simply weather-resistant, not waterproof. Furthermore, submerging the battery in water will allow water inside, which can compromise its condition.
4: AVOID EXTREME TEMPERATURES
You want to keep your batteries away from too much heat or cold. Cold weather drains batteries faster, and rapid discharges are an enemy to lithium batteries.
Heat can be equally bad, if not worse, as too much can lead to overheating the batteries, resulting in excessive wear on the system or catastrophic failure.
