No warranty for 3rd party batteries
Bosch does not approve the use of 3rd party batteries and they say it will void the warranty. E-Bike Vision says they aren’t concerned by this and they consider themselves to be the battery specialist. It’s recommended you install the original battery if you bring your bike to the dealer for service or repair. The distributor has made the following statement.
E-Bike Vision does not find this limitation a big problem because they’re confident their batteries are high quality and they will never harm the motor system. Also, they focus on the after market and a lot of bikes will be out of waranty when the original battery needs to be replaced.
The batteries are fully compatible with the diagnostics tools from the various motor brands. There are no error messages when connecting the battery to the different diagnostics tools, so there is no trace of a 3rd party being used. E-Bike Vision has not had a single failure caused by their batteries.

Testbike 1: 2019 Ghost Hybrid Teru 2.9 500 Wh
The bike has covered just 650 km and the original battery is in good shape. This bike belongs to Jan and it’s a size Large. Both batteries fits, but the bottle cage gets very close to the 624 Wh battery. We couldn’t really fit a bottle in the cage. On a smaller frame, the cage would probably have to go.
Test loop
The batteries are tested in a 20 km loop that takes about 60 minutes to ride. The surface is asphalt and gravel. One section is a steep hill with loose gravel that will draw a lot of energy. We monitor the remaining range estimated by the Bosch Purion display. We have several checkpoints where we record distance and remaining range. The remaining range figures can be a bit confusing mid ride, but they make sense at the end of the ride. Remaining range isn’t always a very reliable number. But the numbers add up when riding the same loop, with the same rider and the same bike. Weather conditions, temperature and speed was about the same for all rides. The entire test was done with maximum motor assistance, Boost-mode. We also include the original Bosch 500 Wh battery in this test.
| START | Remaining range | Battery bars |
| E-Bike Vision 360 | 47 km | 5/5 |
| Bosch 500 | 64 km | 5/5 |
| E-Bike Vision 624 | 78 km | 5/5 |
| END – 20 km | Remaining range | Range used | Battery bars | Our calculated range |
| E-Bike Vision 360 | 19 km | 28 km (60%) | 3/5 | 34 km |
| Bosch 500 | 36 km | 28 km (44%) | 4/5 | 46 km |
| E-Bike Vision 624 | 54 km | 24 km (30%) | 4/5 | 65 km |
“Our calculated range”, found in the bottom right column will serve as the result of this test. You will find the explanation for how we ended up with these results at the bottom of the article. There are no big surprises here. Range and capacity correlates quite well. A bigger battery will take you further. But could there be a difference in how efficient these batteries are?
Efficiency
We recorded the power consumption when recharging the batteries after each ride in the test llop. The figures show how much energy has been drawn to refill the batteries, charging losses included. So we don’t know how much of that energy actually went into the batteries. But we wanted to see if we got an indication of the power consumption.
| Battery | Power consumed by the charger |
| E-Bike Vision 360 | 220 Wh |
| Bosch 500 | 200 Wh |
| E-Bike Vision 624 | 200 Wh |
Also, we try to calculate energy consumption by looking at gross battery capacity and the our estimated range (battery capacity / estimated range = consumption).
| Battery | Estimated range | Consumption |
| E-Bike Vision 360 | 34 km | 10,6 Wh/km |
| Bosch 500 | 46 km | 10,8 Wh/km |
| E-Bike Vision 624 | 65 km | 9,6 Wh/km |
The data and measurements used for these calculations aren’t highly precise. The charging test could indicate a slightly higher consumption with the 360 Wh battery. We can’t say it’s so for sure, but it makes us speculate. A battery with fewer cells (in parallel) has higher internal resistance, which leads to increased heat loss when power consumption is high. But the power consumption is about the same for the 360 Wh battery and the 500 Wh Bosch battery. Could it be the internal resistance of the Bosch battery has increased slightly due to ageing?
We can’t make a definite conclusion. Based on the data we collected, the batteries performs quite similar. But the results allows for the possibility that the big 624 Wh battery could be more efficient than the two others. Lower internal resistance in the battery could explain this. Regardless, the E-Bike Vision 62 Wh battery performs very well in this test.
Jan’s thoughts
Jan prefer the 624 Wh battery. He enjoys going for long rides in the forest and he need as much capacity as possible when he’s pulling a wagon with camping gear. He usually ride gravel roads. When spending the night out, the battery usually gets quite cold, further reducing the battery range. A bigger battery allows him to be spontaneous and extend the ride if he wants to.
Testbike 2: 2021 Canyon Pathlite:On 8
This is a brand new bike that has covered just a few km. The bike has got a Bosch motor and dual batteries. One battery is integrated in the downtube, the other is an external one. Both batteries are 500 Wh. It’s interesting testing this bike because Bosch has a fairly advance way of draining the batteries. The system is automatically alternatinating between batteries to drain them evenly. Here you don’t empty one battery first and manually switch to the other. And this works fine with the E-Bike Vision batteries. The system swithes as intended and there are no error messages.
We did a long ride with the integrated Bosch battery and the external E-Bike Vision 624 Wh one. As far as we could tell, the estimated remaining range was correct, and the battery bars behaved as expected.
Both batteries had sufficient space in the frame, but we struggled a bit getting them in. We had to squeeze a bit to seat them properly. It seems there is a plastic plug on the downtube that is getting in the way slightly. But it turned out it was the same with the original Bosch battery, so the issue is with the frame, not the batteries. There is room for extras in the size Large frame, such as a bike lock.
We ask the owner of the Canyon bike which battery he prefers. He said he wanted the 746Wh battery. We didn’t test that battery, but weight and size is the same as for the 624 Wh model. He can never get too much range. The big battery along with the internal 500 Wh Bosch gives a total capacity og 1.240 Wh.
Our choice
Both bikes in this test are sort of adventure bikes. So it’s no surprise the test riders prefer the bigger batteries. But I usually go on shorter rides on trails, with a full suspension bike. And I quite like the smaller 360 Wh battery.
Does your bike struggle to cover your daily commute? Then it is of course much cheaper buying the smaller 360 Wh battery and use two batteries for your ride. The bigger batteries cost quite a bit extra. We think the biggest advantage of the 360 Wh battery is the low weight. If you’ve fit the smaller E-Bike Vision LITE battery on your full suspension emtb, you will drop the bike weight by 700 g. We would love to test this battery on the 2021 Lapierre Overvolt GLP 2 Team. The bike has a claimed weight of 21.37 kg, That’s 20.7 kg with the smaller battery. Seems perfect for an afternoon shred on the local trails!
Other E-Bike Vision batteries
There are E-Bike Vision batteries for other motor systems too, like Yamaha. And there will be more. Rumor has it there will be Shimano batteries, and internal batteries for different motors.
Calculations, for those who care
We collected different data from riding the test loop. Some of the info came from the dealer-only app. After going through the data, we decided on using the “remaining range” estimated by the Bosch computer. This was the most consistent data. We recorded remaining range at start and finish. We divide the remaining range by the actual range ridden and we get a constant that says how much remaining range is lost for every kilometer we ride. For the two smaller batteries, we lost 1.4 km of remaining range for every kilometer we rode. The bigger 624 Wh battery lost 1.2 km of remaining range for every kilometer covered. We calculate the actual range for each battery by correcting the remaining range with the constant and adding the distance we rode. Also we took the remaining range at start and adjusted it with the constant. Both calculations gave the same result for all batteries. This is the figure found in the table further up, in the column named “Our calculated range”.
Example: The 360Wh battery lost 28 km after riding 20 km, 28/20=1.4. So 1.4 km was lost for every km covered. The estimated remaining 19 km should last for 14 km of riding (19km/1.4=14km). Total calculated range is 20km+14km=34km. If we take the remaining range at start and divide by the constant, we get about the same result: 47km/1.4=33.6km.
