Which Battery Should I Choose?
For many of our electric bikes we offer four different batteries that are classified by their voltage and amp-hour ratings. The voltage determines how powerful the bike will feel and the amp-hours determine how far you can go on a single charge.
Choosing the right battery for you depends on your individual needs and budget.
|10AH||Experience shows that most people are completely satisfied with the standard 36V 10Ah battery. It usually provides more than enough power and range, and it’s the most affordable option.||The more powerful 48V 10Ah battery is best for riders over 200 pounds and for overcoming steep hills or strong headwinds. It is also the most popular because the extra power makes it more fun and exciting to ride.|
|15AH||The extended range 36V 15Ah battery is best for trips over 25 miles or if you plan to pedal very little (or not at all). It can really come in handy to have excess capacity.||The brand new 48V 15Ah battery is the best of both worlds. It has all the power of the 48V 10Ah battery and the extended range of the 36V 15Ah.|
How far can i go?
The short answer to this question is far enough! Generally speaking, any Pedego battery should last longer than you. We don’t hear many stories of people running out of juice.
With that said, this can be a complicated question because there isn’t a “standard” and everybody makes vastly different claims about range. So we’ll go over some simple elements that can help you objectively predict the range of any electric bike.
All batteries have both a Voltage and Amp Hour rating. If you multiply the two together, you get Watt Hours. Watt Hours is an objective measurement of the actual amount of energy stored in a battery.
Volts x Amp Hours = Watt Hours
This is where it gets tricky, because there are so many variables. On average, you can expect to use between 12-24 watt hours per mile. This number fluctuates so much because of differences in terrain, rider weight, weather, speed, The type of bike you have (Commuters go further than Cruisers which go further than Trail Trackers) and most importantly how much you pedal.
Below is a table with all the facts about each Pedego battery and the estimated range for an average rider.
|VOLTS||AMP HOURS||WATT HOURS||ESTIMATED RANGE (12-24 WH/MILE)|
|STANDARD||36||10||360||25-30 miles (12-24 wh/mile)|
|LONG RANGE||36||15||540||35-60 miles|
Generally speaking if you live in a hilly area the 48 volt batteries last longer than 36 volt batteries as they get you up them quicker, so less energy is used overall in getting you up the hill.
How long until the battery needs to be replaced?
You can expect your battery to last about 3-6 years.
Lithium batteries usually don’t just stop working altogether, what happens is they gradually lose their capacity over time.
Pedego batteries are backed up by an industry-leading three year warranty, where the first 2 years is guaranteed 100% and the third years are pro-rated, based on how long you’ve had the battery. Visit the details here.
To prolong the life of your battery it’s suggested that you avoid discharging it completely, and the big thing is to make sure that you charge it at least once every couple months.
How Long Does it Take to Charge?
A battery will charge is between 3-6 hours with a standard wall outlet.
There is no memory, so you don’t have to worry about discharging it completely, and it’s best to recharge it after each use.
It uses very little energy- pennies to recharge.
And it includes a smart charger that will automatically shut off when it’s done.
Pedego batteries are made up of individual Li-ion cells designated 18650 because of their size (18mm x 65mm). These are very common batteries found in countless consumer electronics, electric bicycles, and even electric cars.
There are basically two types of 18650 cells- those made by the three major name brand suppliers (Sony, Panasonic, and Samsung), and everything else. The name brand cells are much more safe and reliable than the cheaper cells.
Pedego Electric Bikes use premium cells made by Samsung, which is the world’s largest Li-Ion battery supplier.
The benefits of these cells are three fold:
The cells we use exceed all the UL requirements, which is the gold standard for battery safety certification.
Each cell is protected by a puncture resistant steel cylinder, and they are separated from each other in the battery pack to prevent fire.
Pedego is able to offer an industry leading three year limited warranty because of technological advances that have prolonged the life cycle of our batteries.
The manufacturing process and quality control of the cells themselves has significantly improved over the years, and there is an extremely low failure rate.
The connections between the cells have also evolved and improved to prevent bad connections and premature battery failure.
The number one reason 18650 cells are so wildly popular is their incredible performance capabilities.
They are remarkably energy dense delivering an abundance of power (up to 675 wh/L and 252 wh/kg) with very little space and weight.
These little cells really deliver the goods!
Can i Charge the Battery by Pedalling or braking?
The battery is charged by plugging it into the wall, and the more you pedal the farther you can go. Your pedalling conserves the battery, but it doesn’t actually charge it.
The technology does exist that would allow you to charge your bike by pedalling, but we’ve found that it just doesn’t make sense for electric bicycles. It adds a lot of expense to the bike for very limited range extension.
