E-bike batteries are arguably the most vital part of your electric bicycle. They dictate how far you can go on one single charge, how effectively your motor operates and how smooth your ride will be overall.

One of the most common questions we receive is how to maximise your electric bike battery range. The range is how far your e-bike will go when it’s fully charged. It’s based on a number of variables, which include the battery capacity, pedal assist levels you’re using, terrain, rider weight, tyre pressure and weather.
Pick a larger capacity battery and you’ll generally have more range. For instance, a 500Wh battery will generally take you further than a 300Wh battery, assuming all else is equal. That said, there are lots of things you can do to get the most range out of your battery, regardless of which one you choose.
Ride economically first. Apply lower levels of assistance on flat ground and reserve the higher modes for steep hills or when you really need assistance. Pedal regularly instead of using the motor alone. Maintain your tyres at the correct pressure, since low-pressure tyres create greater resistance and exhaust the battery quicker.
Battery maintenance is also very useful. Don’t let your battery drain completely too often, and don’t keep it fully charged for long periods of time. Keep it at room temperature and out of direct sunlight. Cold temperatures drain performance, so during winter, it would be ideal to keep your battery indoors when not in use.
We also recommend charging with the original charger that your bike comes with or one specifically approved for your battery type. Charging with improper chargers can shorten the battery life or even damage it permanently.
By adhering to these easy habits, you can maximise the day-to-day range of your e-bike as well as the overall lifespan of the battery itself.
Not all e-bike batteries work with all e-bikes, and as such, getting the correct one for your bike is essential. Voltage, amp-hour rating, connector type, and mounting type are all factors to be considered when shopping for a replacement or upgrade battery. We carry a wide variety of replacement electric bike batteries for some of the top e-bike brands. Whether you’re swapping out a used battery or upgrading for longer rides, we can help you get the perfect fit.
If you are not certain which battery you require, then our customer service can assist. We can use the model number of your e-bike or even a picture of your existing battery, and we will determine what the suitable alternatives are. Our goal is to remove the guesswork and enable you to start shopping with certainty. Some of our batteries feature built-in LED displays so you can check your charge at a glance. Others are quick-release batteries, so you can take them indoors to charge without having to bring the entire bike along, especially handy if you use a rear rack.
Our batteries are all based on high-grade lithium batteries, offering the optimal blend of power, weight and long battery life. We also include comprehensive product specs and charging guidelines, maintenance and storage tips so that you can get the most from your investment. As a general rule, choosing a quality battery means better handling, better performance, and less worry about the overall weight of your new bike. Whether you’re upgrading from lead-acid batteries or simply replacing a worn unit, we’re here to help you ride farther and smarter.
