Does your Fiido D4S electric bike need a new power source? If so, a battery for the Fiido D4S could be the key to unlocking the full potential of your ride! In this article, we’ll take a closer look at what makes this battery a great choice for e-bike enthusiasts. I’ll talk about its specifications, benefits, how to use it and why it’s worth having. Get ready for a deep dive into the world of e-bike technology – in a simple, accessible way!
What is the battery for the Fiido D4S?
The battery for the Fiido D4S is the heart of this popular folding electric bike. The Fiido D4S has won acclaim for its lightweight, mobility and performance, and the battery is the key component that drives all these features. Powered by lithium-ion technology, the 10.4 Ah, 36-volt battery provides the robust range and power you need for your daily commute, weekend rides or city exploration.
Why is the battery so important?
An electric bike without a working battery is like a car without fuel – it supposedly works, but the potential remains untapped. The battery for the Fiido D4S gives you the freedom to get around without worrying about it draining quickly. It allows you to cover up to 80 km on a single charge in assisted mode, making it ideal for both urban cyclists and those who enjoy longer routes.
What do these numbers mean?
-
- Capacity 10.4 Ah: This is a measure of how much energy the battery can store. The more amp-hours, the longer the route you will travel without recharging.
-
- Voltage of 36 volts: Guarantees enough power to drive the 250 watt motor in the Fiido D4S.
-
- Range up to 80 km: Ideal for people who need a bike for their daily commute or trips out of town.
-
- Charging time of 7 hours: A full charge takes as long as a restful night’s sleep – you plug in in the evening and you’re ready to ride in the morning.
In my opinion, these parameters place the Fiido D4S battery among the top e-bike accessories in this price class. It is not the most powerful battery on the market, but for a lightweight folding bike like the D4S it is perfectly balanced.
Benefits of the battery for the Fiido D4S
Why is it worth investing in this battery? Here are a few reasons that will convince even the sceptics:
1. long range
The range of up to 80 km in assisted mode is a real game-changer. You can drive all day without worrying about the battery running out. In full electric mode, the range is around 40 km, which is still great for an urban bike.
2. compact design
The battery is integrated into the frame of the Fiido D4S, which not only looks aesthetically pleasing, but also makes the bike easy to transport when folded. No protruding parts – everything is neat and functional.
3 Durability
Lithium-ion technology means the battery will last for hundreds of charge cycles before it starts to lose capacity. With proper care, it will last you for years.
4. easy to replace
If your original battery has worn out, replacing it with a new one is easy. You don’t need special tools – it’s a plug-and-play solution.
5. the ecological choice
An electric bike is environmentally friendly in itself, and a long-life battery further reduces your carbon footprint.
How do I look after the battery for the Fiido D4S?
To make sure your battery serves you for as long as possible, it’s worth following a few simple rules. Here is my list of tips:
-
- Charge regularly, but not to zero – Trynot to let it fully discharge. Ideally keep the charge level between 20% and 80%.
- Store in the right conditions – Keep your battery between -10°C and 50°C. Avoid extreme cold and heat.
- Use original charger – A dedicated 42V 2A charger will ensure safe and efficient charging.
- Check the condition before a long break – If you don’t use the bike for a few weeks, charge the battery to around 60% and switch off the power.
- Avoid moisture – Although the bike is IP54 rated for water resistance, it is better not to expose the battery to prolonged contact with water.
In my experience, proper care of the battery can extend its life by up to 20-30%. This is a small effort for a huge benefit!
How do I replace the battery in the Fiido D4S?
Replacing the battery in the Fiido D4S is simple and will take you no more than 15 minutes. Here are the steps:
-
- Switch off the bike – Make sure the power is cut off.
- Unlock the battery – Use the key (if supplied) or unscrew the fixing screws.
- Remove the old battery – Gently pull it out of the frame.
- Insert the new battery – Make sure the contacts are a good fit.
- Secure and test – Close the case and check that the bike turns on.
