Electric plans for 2025. 6 kWh battery for a scooter?

Let’s talk about plans for this year and the ideas I want to implement regarding my electric transport during 2025.

From time to time, our plans change, and this year I decided to completely close the issue of my electric transport. Of course, we are talking about electric bicycles and… a scooter? Yes. This year the fleet will be updated. And the purchase of the year should be a two-seater electric scooter with a cabin. Let’s start with it.

Canopy

Previously, I looked at different models and chose the model that is called Vega Help Canopy 650 in our market . This work of art looks something like this:Among the basic characteristics:
– 10″ wheels;
– 650 W engine;
– 60V/20Ah acid battery;
– full roof (with a cover that completely covers the sides);
– two full seats for the driver and passenger;
– a fairly capacious trunk (instead of a passenger);
– additional rear trunk.

The motor, of course, is not very powerful, and this was its main disadvantage. The advantage is two full seats (in fact, they say that two small people can fit in the back). Theoretically, you can put (spoiler) 60V/100Ah LiFePo4 in the battery compartment, which will last for…many kilometers. At the same time, according to preliminary calculations, the weight (compared to the lead at the time of purchase) will increase by a small 3.5-4 kg. The plans also included installing an additional motor in front instead of the wheel (so as not to change the main one), thereby allowing this vehicle to go up any mountain and have greater stability when driving in winter. But the plans have changed somewhat.

Nadya

Despite the fact that the model that I (most likely) will buy has Chinese roots and an exclusively Ukrainian name, I would prefer to call it “Canapeshka”. Because all these “scooters with a roof” are just copies of the outstanding Honda Gyro Canopy model . So what kind of Hope is this?

As such, “Nadya” does not exist. This is a Chinese scooter, which can be googled under the name Anlugi tricycle . The wheels are slightly different from the model sold in our market (MotoLeader Nadya), but otherwise the model is very similar to the above-mentioned scooter from Vega. However, there are also differences:

• battery 72V/20Ah (+12V bank);
• the additional basket disappeared;
• the engine became 1000 W;
• there is no additional rain cover included;
• A slightly different shape at the back, a slightly different headlight, different wheels, a different fork. Nobody installed disc brakes either.

The differences are small, but they are more than enough to see the difference in power. I am not sure that with a passenger even a 1000 W motor will be enough to ride down a hill, but the dynamics and traction of this model, theoretically, should be somewhat higher. I do not consider speed to be an important characteristic, since 25-30 km/h is more than enough speed for such equipment (let me remind you, the basic manufacturers claim 40-50 km of mileage, but I do not really believe in it). The difference in price between the models is quite insignificant, but it is there. And not in favour of the Vega model. One of the main arguments in favour of buying this particular version was the ability to order the equipment in a disassembled state (the one in which it comes from the factory) and assemble it yourself.

Also one of the things that distinguishes this model is the low gear. In the photo from the seller there is a rather interesting lever:

According to the description on the website, it should be responsible for downshifting, which could make this model more powerful compared to its competitors.

A similar version of the electric scooter is available from Yadea, and all this happiness looks something like this:

Plans

Despite the fact that the thing is being bought new, it is planned to make some changes almost immediately. First of all, this will concern the Kanapeshka battery. Ideally, if space allows, I would like to assemble a battery with a capacity of 105 Ah. The voltage can be either 60V or 72V, since most likely the motor controller will allow it to work at either voltage. It is quite difficult to calculate the real range on such a battery, since there are many nuances. I would like to calculate from the ideal value “1 kilometer = 1Ah”, and then the battery should last about 100 km. Considering that the nearest city is 25-30 km away, this will be more than enough for a trip there for two. From the point of view of economy, this looks absolutely fabulous. Let’s do some calculations.

One trip in a shared car costs $3.5 per person, or $7 for two, and $14 for a two-way trip, respectively. I calculated that the cost of the battery will be approximately $666 (taking into account the sale of the native car, the amount will be partially reduced). $666 is 50 trips. Or 50 battery cycles. LiFePo4 have approximately 2000 and above cycles, after which the battery will still have 80% charge. If we take even 1,000 charge cycles, it will be possible to overcome at least 100,000 km on this. This is a considerable figure even for a car or motorcycle. For an electric scooter, it seems completely fantastic. So is it expensive to pay about $700 for a battery? I think not.

The question remains about using transport in winter. And here again, using a battery with a voltage of 72V will help us. The fact is that this voltage is equal to two bicycle batteries (2x36V, respectively). So theoretically, we can use two parallel batteries. I just had plans to upgrade the batteries for our three-wheeled friends (i.e. bicycles), collecting a pair of batteries with a capacity of 25Ag. A lithium battery with such a capacity should be more than enough in winter for driving around the city. Such a battery can always be removed without problems and brought into the house, so as not to worry about storing it in a cold garage. And the main battery (72V/105Ah) can be used for backup power at home in the winter so that the elements do not stand idle.

Batteries

Now I am on the way to assembling the first of two batteries with a capacity of 25Ah. It will all be assembled on EVE INR21700-50E 5000mAh 15A cells . These should be powerful cells that will allow you to use these batteries to the maximum. The case for this whole thing will be quite typical:

As for BMS, I decided to go further and, if possible, take something good right away, that is:

JK-BMS has proven itself very well in terms of monitoring the condition and operation of the battery in the backup power system that I am currently using. That is why I decided to stop at it. What will the final cost of the battery be?

Battery case with nickel plates $48.48
BMS 60A 8-17S 0.6A, Built in BT $30.74
Batteries EVE INR21700-50E 5000mAh (took 55 pieces, with a spare) €91.13 (~$100.92)

Total $180.14 for a 36V/25Ah battery. This is about $178. By selling two old 36V/10Ah batteries for $83, we will get an updated battery for $12 more, with a capacity of 5Ah more and a completely new one, with a high-quality BMS. I think it’s worth it 🙂

Theoretically, 5 parallel cells will give about 75A of current at 36V. So a 60A BMS will be more than enough (do you know many options for using bicycle batteries that can produce more than 2 kW of power?). This is much more than what a 400W bicycle motor or a 1000W motor of a planned scooter requires. This means that the battery will be used without overloads.

As I implement my plans, I hope to consistently share my experience here, the problems I encountered during implementation, and what the outcome will be, so see you soon 🙂
