Lots of customers used a 52V battery to connect with a 48V30A controller.Then the display might shown high voltage error 07. So BAFANG has update the 48V30A controller to 52V28A, then it can compatible with both 48V and 52V batteries. For a 52V battery it will show 100% on the display when connecting to the 52V controller, but for 48V battery,it will show 84%. We're still trying to resolve this matter,it's not a big question, it won't effect any functions.
4. Can I charge the bike without the battery?
Yes! You can access the charge port and the USB port on all EUNORAU bike models without removing the the battery from the bike.Also your battery can be brought inside and set to charge.
5. How long does the battery last?
Batteries typically last 5-6 years. However, this can vary depending on how much you use your e-bike. EUNORAU batteries will still deliver more than 80% of their original capacity after 500 charge cycles.
To prolong the lifetime of the battery there are several procedures that can be followed. The main ones include:
1.If storing the battery for more than 2 weeks it should be kept in a cool, dry place with a 70%-80% charge remaining in it.
2.Avoid running the battery completely flat. Charging batteries when they still have 10-15% of power remaining will significantly extend their lifetime.
6. How long does it take to charge an EUNORAU Lithium Ion Battery?
Depending on the battery and charger type a full battery charge will take between 3-8 hours
7. Does the battery charge when pedaling and/or braking?
The technology for charging batteries through pedaling hasn't reached an efficiency level we consider satisfactory yet, but we're always looking to innovate on our models.Currently only MAX-CARGO and JUMBO apply this function.
Regenerative braking is great in a car or motorbike with higher inertia but a bike isn’t heavy enough to allow the breaks to generate enough energy to significantly charge the battery.
8. Do EUNORAU batteries have an internal battery management system (BMS)?
All EUNORAU batteries have an internal BMS. The BMS regulates the current and voltage entering and exiting the battery. It prolongs the lifetime of the battery and ensures all the cells are drained at equal rates. It also protects the battery from transient events and monitors the temperature of the cells.
9. What temperatures can EUNORAU Bike handle?
The battery is the major component on the bike that may need extra care in extreme weather. The optimal operating temperature for the EUNORAU batteries is 10℃ to 55℃.
10. Can the bike get wet?
Yes! We take our bikes through mountain streams and rain almost every day. The motor and electronic components are sealed and built to take a beating.
11. Are the bikes waterproof?
EUNORAU bikes are water resistant which means they are able to resist the penetration of water to some degree but not entirely. Riding in the rain and washing your bike won't cause any damage but the electronic components are not recommended to be exposed to water for long periods of time.
Note: The battery can only get wet while it's inserted into the battery housing.
12. Can extreme temperature damage EUNORAU bikes?
The only component that you need to be concerned about when operating in extreme temperatures is the battery. The optimal operating temperature for a EUNORAU battery is 10℃ to 55℃. Battery efficiency can be severely limited outside of these temperatures and should be avoided as much as possible.
