The eXTender Mod is a robust, weather resistant and easy to use adapter that allows us to connect an off the shelf Ego 56v battery to our Fuel EXe. It can extend the range between 30-35%.
$249 NZD (inc. GST and shipping). Approx $130 USD excluding tax
$40 NZD / $25 USD international shipping
It extends the range of our TQ Fuel EXe by 30-35% using a 2.5Ah (140Wh) battery. It is completely removable and requires no modifications, bolting to the drinks bottle holder and plugging into the charging port. The bike learns that the Ego battery is connected and the percentage reports fairly accurately.
The whole system is available now at around 50% the price of the TQ extended battery option (including if you need to buy an Ego 2.5Ah battery and charger). If you have a near new Ego 2.5Ah battery and charger already this will be an even cheaper solution. Shipping now with a 1 week lead time.
History of the Ego 56v batteries:
These have been used in eBike applications for many years and I have personally used them for 4 years in another PEV application (If you search for Ego eBike you will find many examples).
They are extremely durable, water resistant, use Samsung cells and have their own battery management system. They are the correct voltage to match with the TQ Fuel EXe system (14s, or 50.4v nominal).
Ego batteries are readily available at many hardware shops and are backed by a 3 year warranty in most cases.
eXTender Mod design and manufacture:
This is a 3d printed adapter plate, Ego adapter and plug that have been designed specifically for the Fuel EXe. The design wraps around the frame and is made of a combination of materials for extreme durability. It has held up to all tests (hundred of KM, bike trails, jumps and static tests) and I believe it to be stronger mounting system than the TQ extended battery option. Once I have brushed my knee against it when falling forward, but otherwise you don't normally get close to it as there is plenty of clearance when you peddle.
eXTender Mod use:
REQUIREMENT: Both bike and Ego battery must be fully charged before connecting together. There are multiple fail safe systems to protect both Ego battery and the TQ system (inbuilt to all 3 systems), but connecting them at different charge states should never be attempted.
How to use:
1. Charge both Ego battery and bike to full (separately)
2. Unplug the eXTender from the bike charge port (recommended)
3. Slide the Ego battery onto the eXTender Mod (it self locks into place)
4. Turn on the bike
5. Plug the eXTender into the charge port
6. Ride immediately (recommended)
The whole process takes around 10 seconds. Installing the system the first time takes around 20 minutes.
There are many reasons why the above procedure should be followed. More details will follow.....
eXTender Mod results:
I ride with another Fuel EXe rider who has 1kg weight difference to me and we generally ride at the same speed. Typically I end up having around 1 hour extra of riding time or 30-35% additional battery according to the TQ percentage. In other tests I have ridden the same 36km flat loop and ended on 4% battery without the eXTender Mod and 34% with it (using an Ego 2.5Ah battery).
eXTender Mod limitations:
Currently testing has only been done with an Ego 2.5Ah (140Wh) battery. Other Ego batteries are compatible but cannot fit on the 9.7 and above due to the piggback reservoir. The EXe 9.5 may allow for an Ego 5.0Ah battery but this hasn't been tested. The eXTender Mod also cannot be used on it's own, it needs the main TQ battery to be connected.
There are a number of other advantages and disadvantages compared to the TQ extended battery option which I will disclose in future posts, including more photos and details.
Please ask any questions you have.
