Electric bicycles, or eBikes, have revolutionized the way we think about cycling. No longer is it just a physical activity, it’s now a viable mode of transportation for long distances. One of the latest innovations in this field is the dual battery eBike. But what exactly is it, and how does it work? Let’s dive in.
Understanding Dual Battery eBikes
A dual battery eBike is an electric bicycle that uses two batteries instead of one. These batteries are mounted on the frame of the eBike and work together with the electric motor to increase the bike’s range. This means you can travel longer distances without needing to recharge.
There are two main types of dual battery eBikes:
Mid-drive dual battery eBikes:
The motor and batteries are positioned at the bottom crankset. This gives the rider different levels of assistance and a more extended range. Also, a low-centered positioning means better balancing. With mid-drive dual battery eBikes, you can remove the rear wheel without interfering with electrical connections.
Hub motor dual battery eBikes:
The battery is at the rear or front wheel. These eBikes are cheaper and lighter compared to their mid-drive counterparts. And because the dual batteries work in conjunction with the internal gear systems, they are nearly maintenance-free.
Eunorau offers a range of eBikes that support the installation of a secondary battery. This feature provides riders with the flexibility to extend their range as needed, making Eunorau eBikes a great choice for both commuting and leisure rides.
How Does a Dual Battery eBike Work?
Power Source:
The two batteries serve as the power source for the eBike. They supply the necessary energy to the electric motor that propels the bike.
Intelligent Switching:
The system intelligently switches between the two batteries. It discharges the fuller battery first until both batteries have the same charge level. Then, both batteries are discharged evenly and in parallel. This method ensures an efficient use of energy and prolongs the life of the batteries.
Motor Assistance:
The electric motor uses the energy from the batteries to provide assistance to the rider. Depending on the level of assistance set by the rider, the motor can either partially or fully propel the bike.
Extended Range:
Because there are two batteries, the range of the eBike (the distance it can travel without needing a recharge) is significantly extended. This is particularly beneficial for long rides or commutes.
Increased Power Output:
With two batteries, the eBike can deliver more power output. This is especially useful when tackling steep inclines or rough terrains.
The Benefits of Dual Battery eBikes
Dual battery eBikes offer several benefits:
Extended Range:
Dual battery eBikes have up to twice the battery range of their single battery counterparts. This is especially useful for people who rely on eBikes for daily commuting, as it provides them with the flexibility to take longer routes and run errands if need be without having to worry about the concern of battery depletion.
Increased Power Output:
With two batteries, the eBike can deliver more power output. This is especially useful when tackling steep inclines or rough terrains.
Safety:
One advantage of dual battery eBikes is safety. In case of unexpected situations, you can enjoy the ride without worrying about battery failure. Whether you’re cycling in a remote location or running late for an appointment, you don’t need to carry a spare battery.
Versatility:
For some models, you can switch between the batteries when needed (especially on longer trips). The added versatility means you get more juice to reach your destination.
Cost-Effective:
Hub motor dual battery eBikes are cheaper and lighter compared to their mid-drive counterparts. And because the dual batteries work in conjunction with the internal gear systems, they are nearly maintenance-free.
Consistent Power Output:
When using the two batteries in parallel, the power output remains consistent, ensuring a smooth ride.
Less Time Charging:
With dual batteries, you’ll spend less time charging and more time on your bike.
Remember, the quality of dual battery balancer circuits can vary widely. Therefore, it’s crucial to do your due diligence before using such a system. It’s recommended to ensure that the dual battery module has UL-certification.
Eunorau's batteries are UL tested for safety, making Eunorau an excellent choice for a secondary battery purchase. Upgrade your eBike with Eunorau for a safer, farther ride.
