Hi! Thanks for checking out one more project of mine. Hope you will like this one as much as I did.
Since my last 1500W E-Bike build attracted a bit of attention (you can check it here 👉 • DIY Electric Bike 65km... ), I got many requests on building a more budget friendly e-bike. So I decided to go with a 1000W rear wheel kit which packs a great punch for the price. The installed conversion kit can reach 48 km/h (30mph). There are many programmable options on the LCD itself, and the best part is the Bluetooth connectivity of the BMS. Using the XiaoXiang app the battery can be turned on and off. It also provides temperature, range, current, cell group voltage and lots of variable parameters.

[@thetechgenie7374]

Wow I built my own ebike battery packs for years. Spot welded and nickel strip for higher current and etc. Never thought to heat the top plastic to remold the BMS controller to fit into case as wasn’t a issue on smaller packs. Going to do that now on the new 24AH pack currently building as have space on top to fit into frame. Thanks for the detailed video as now figured out how to do a bigger pack while still being able to fit it into bike

[@DonnyTerek]

Thank you a lot! Glad to see that even an experienced builder can bring something new into their workshop after watching one of my vids. The BMS fits well if the same battery enclosure is used for a 14S6P configuration, since then a few holders can be snipped off to allow the BMS to sit flush. Having the 13S7P battery takes up all the space in the holders so yeah, it gets a bit tight for the BMS to be fitted inside the enclosure. The only disadvantage of having the case heated up to shape it around the BMS is that it expands the hole that is used to cast the plastic inside a mould. That can be easily patched but takes a few extra hours. Thank you once again.

This was hugely helpful for me, and Im happy I found this video since I have the exact same BMS fitting problem with the battery case, but I never thought of heating the case and fitting the BMS like that, genius! What is the reason for the hole in the top where the BMS is?

[@DonnyTerek]

That's awesome! Glad to see I could help you out here. The hole is caused by heating the plastic case. I guess that is the place where the plastic is injected into a mold.

[@robertkelly469]

The most difficult thing to your videos is the battery build, very technical but also very detailed I would love to have a go but I probably would just make a balls of it, great to see it done though. Excellent video as always.

[@DonnyTerek]

Thank you a lot! I definitely agree, the battery build is the most difficult part.

Really awesome build..meticulous. 👍I’m surprised you didn’t manufacture the torque arms instead of using the hose clamps.

[@joshuadughi]

Hi, Donny. Thank you for composing such a well detailed video of this effort. I will use it as a reference as I slowly work to converting my street bicycle to an e-bike. I have 2 questions: 1) Can you provide me the break-down of the math that allows you to say that a 13s 7p configuration will give you a 1000 watt solution? (I know that each (new) 18650 cell is supposed to have a nominal 3.7 volts.. but how does that bring me to 1000 (more-or-less) watts? 2) If I have 100 x 18650 cells, and they fall (randomly) into ranges of power - that I document to be from, let’s say 2150 mAh’s and 2450 mAh’s, then, it isn’t/wasn’t clear to me from THIS video how I ought to group batteries covering a rather broad range of powers - into a block of 7 parallel cells. Can you give me - us - some guidance on this - or possibly direct me/us to a video that addresses this matter? Thank you so much! Josh

[@DonnyTerek]

Hi, Josh. Thank you for the kind comment, much appreciated. Glad to see that my video will be used as a reference to help you build your own. I won't be getting into too much detail on my answers but will do my best to provide some info: 1) A 13s7p configuration means that you are connecting 13 packs (made up of 7 cells connected in parallel) in series. A series connection adds up your voltage from each cell pack 13 * 3.7V = 48.1V. Note that 3.7V is the voltage of a half empty battery. Now the 7 cells that are connected in parallel give us a multiplied capacity from each cell. Let's say you are connecting 7 cells in parallel that are approx 2400 mAh each. That gives us 7 * 2.4 Ah = 16.8 Ah of battery capacity with a voltage of approx 48V. Power is equal to voltage times amps. To get 1000W of power from a 48V battery, we need 1000/48= 21 Amps of current. This amount of current will be drawn from each parallel group of cells that are connected in series (13 groups of 7 cells which are connected together). This results in 3 Amps of current draw from each cell (21 Amps / 7 cells = 3 Amps). 2) You need to group the 7 parallel cells in the way that would result in a total capacity that is close in each of the 13 groups. Let's say you group 7 cells with a capacity ranging from 2400 to 2500 mAh in total, and the total capacity for this group that you get is 17150 mAh. Your next group of 7 cells is 18000 mAh in total. There is quite a difference in capacities from these two groups of 7 cells in each, so you need to swap a few cells between the groups to reach the optimal configuration where the total capacity is as close to each other as possible. That's where the spreadsheet comes in help since you can write down each cell capacity and then 'stack' them on the spreadsheet to see how you can achieve that each group of 7 cells comes with a similar capacity. Hope this helps, best of luck! Thank you.

[@E-BikingAdventures]

That's assuming those are rated 1C . If they are 2C continuous, you don't need to worry about it. 1500w! No problem.

[@tar2trail448]

loved this there were small little things you did that really was brilliant 👏 battery case is ingenious. just out of curiosity though how comes you didn't use the limit screws on the derailleur to set position rather then the cable?

[@DonnyTerek]

Wow, thank you! The limit screws only adjust the derailleur closest or farthest from the cassette. The tension of the spring and cable keeps the derailleur in place well.

I have my old Iron Horse full suspension bike that still works great. I plan on making into an electric bike. I was looking at one of the frog battery holders for the seat post since I don't have much room for one in the center. Or a rack mount for full suspension toss a big 20ah on it should work well.

[@DonnyTerek]

Cool! Would to see how your build turns out.

[@marcelmihai]

Looking awesome! Why did you choose that spot for the bms, and not that spot at the front with the angled part (cut loose and bend a flap) and then also seal it with sealant? Can you post a dropbox link of your spreadsheet to match the 18650? What is the reason you changed the charging plug in the box? Can this plug not load 5 Ampere?

[@andreasnguyen2540]

The bms took up what looks like a little more that 2/3 of the length of the battery, with the cells there as well it simply wouldn't fit

amazing mate have u got a the link for the sensor cables for the brakes i need some with SM female connector ? cheers

[@Matt-og5kd]

Hi Donny, awesome build, looks very neat and the cable management looks very professional. I am trying to understand the wiring of the bms, battery and the battery connector before I try this out myself. at around 13:45 you solder a discharge wire from the battery positive, and at 14:50 it looks like you connect it to the positive lug of the battery connector. There is another "output wire" going to the negative end of the battery connector, but you only filmed the B- and B+ wires being soldered to the battery. Where is this other "output wire" coming from?

[@Matt-og5kd]

is it just the C- from the bms?

Works just fine to this day after more than 1200 km! Had a few issues at first of the axle nuts loosening, but tightening the nuts and torque arm even more solved the problems. Hope this helps.

[@Ferrari255GTO]

I watched a video on a bike with a similar rear triangle to this one. They went to actual trails and it was terrible, it would constantly smack the seat post, so much in fact that it was almost impossible to move the seat post afterwards because the body deformed,, but for urban or plain dirt paths it should be good.

[@Gs-rg2vo]

Love the build I have an old bike laying around I’m gonna try it just wondering why you put a single speed is it possible to have a entire cassette?

[@Debbiebabe69]

You can have front and rear gears, however you rarely use them on a powerful hub motor ebike. At higher speeds you are pretty much riding a motorbike and all the pedals are for is to fool police/bystanders into thinking it is a pedal bike so you dont get your bike destroyed. At low speeds, simply setting assist to its lowest level allows you to pedal on your highest gear with little effort, so you dont need all the lower gears. Ive still got gears on both my ebikes, but ifI get round to it I will be removing them, to remove stress on the frames (I had to press the frames outward to fit both the motor and the rear cassette).

[@DonnyTerek]

Thanks! Hope you give this build a try. Since this bike is mainly used on flat city roads, extra gears would not be used much. A single gear allows for a smaller tooth number in the back, which combined with a large chainring in the front, allows the rider to pedal more efficiently at higher speeds. It also cleans up the cockpit since a shifter for the rear derailleur is not needed.

I'm going to be building a similar battery 13S7P using an Aliexpress sourced Polly DP-9 battery case and a Daly 13S/40A BMS measuring 61mm x 80mm x 12mm. Would you know whether a BMS of that size will fit without remodelling the case like you did? I was hoping there would be room without major surgery.

Hi, I'm looking into converting and I have a few questions. 1. In your previous 65km/h build you used 8a 35e Samsung cells vs. 5.2a 26f here, which is not considered a high amp cell as witnessed by my laptop battery which has the exact same cells. "Knowledgeable" people on the internet have said using pc cells for ebike is a big no no, but seeing how you've done it I'd like to hear from you on how it compares with 8a cells. I guess slower acceleration and faster cell wear are among the issues, but would like to hear your thoughts. 2. I was quite puzzled to see you go with a single speed freewheel but no belt drive. I thought it's a no-brainer for such a setup, no? 3. Seeing how your rear caliper mount doesn't support 203mm disc, why didn't you go with a smaller one? 4. Do you know why those chinese controller boxes are so large if only half the space is occupied? Have you considered storing the excess cables in there instead of a "black box"? Alternatively have you considered cutting out the excess cables altogether? Thanks in advance

[@DonnyTerek]

Hi! 1. For this 1000W build a high current rating on the battery cells was not needed. These cells are not genuine but perform quite well. The motor will pull a maximum of around 1500W, so each cell will need to output just around 5 Amps at max load. These cells are actually good for up to 7 amps of current draw. And if they are used in laptops, it doesn't mean they can't be used for higher power applications like this e-bike build. And after more than 1500 km with this battery, it is still doing well and pushing the bike with no problems. 2. I don't see a need for a belt drive considering the relatively high cost compared to the readily available and super cheap chain driven parts. And after more than 1500 km on the odometer, the chain works great with almost no maintenance done to it. 3. Bicycle frames are generally (if not all) are built for 160mm brake discs. To accommodate a large brake disc like this 203mm one I used, an adapter is used. For an e-bike like this it is recommended to use larger disc brakes for better heat dissipation and braking power. 4. I guess a larger box is better for heat dissipation from the transistors that are mounted directly to the sides of the case. I wouldn't recommend trying to fit the cables and the connections inside the controller case since they will be difficult to access if you need to unplug some connectors and can cause shorts if any connections are exposed so an additional 'black box' is not such a bad idea. I did cut some of the excess cables to make it easier to fit inside the box. Hope this helps! Thanks for watching.

Hi donny,I want to ask ? I have a 1000 watt 48 volt rear engine. so I want a battery that can last 8 or 10 hours a day or the longer the better? so how many volts and ah battery size? because I'm a bicycle food delivery…. Thank you donny

[@DonnyTerek]

Hi! The needed battery size highly depends on the rider's weight, terrain, speeds, how much you pedal, etc. For a regular DIY e-bike you most likely won't be able to fit more than 20-25 Ah battery. I would suggest you go with a 48V 20Ah battery and check for how long it is enough for you. Perhaps have a second one that you can safely charge while the first one is being used.

[@Debbiebabe69]

if you have a 48 volt motor and controller, use a 48 volt battery. As for ah, the more the better if you are wanting to ride all day, so fit the biggest you have space for in your frame. 10 hours is a lot though, so you probably want to buy 2 batteries and keep one on charge.

[@jj74qformerlyjailbreak3]

That’s a beautiful battery. I really like that spot welder. I’ll check your description for links. God Bless.

[@DonnyTerek]

Thank you! Much work went into this build.

[@brian1675]

That controller which is huge

[@24pavlo]

What's the point of the derailleur if you have a single speed?

[@DonnyTerek]

Works as a chain tensioner.

[@notinvited5148]

18:48 why didnt you put the fluid but before you did when drilling?

[@DonnyTerek]

It's not necessary for drilling aluminium.

[@kevinorghidan4384]

Where are you from, I wish you could build my battery like yours, you know what to do. Nice build, nice changes. I want to make my bike electric, but still don't know what battery I'd good for range, for a motor 48v 1500w rear hub

[@DonnyTerek]

Hi! I'm located in the EU. Thanks! I'd recommend you go with a 52V (14s) battery with a capacity of at least 18-20Ah. Will give you plenty of speed and range. I used a battery like this in my previous e-bike build video.

[@kevinorghidan4384]

@@DonnyTerek where from eu, I'm in 🇪🇺 too. I wish I could get a battery that good, it's a little bit expensive, but it will be very good for range, to go from A to B 20 km distance a land 20 more to came back.

[@DonnyTerek]

Feel free to contact me by email which you can find in my channel's 'about' section or through Instructables which you can find in the description of other videos if interested.

[@kevinorghidan4384]

@@DonnyTerek I will , thank you very much for info. And great video I will use this to guide myself when I'll build mine.

Oh my hell, I watched the whole video, so amazing. I just zip tie everything lol 😂

[@DonnyTerek]

Haha, thank you a lot!

[@Velastroll]

Que clase de Vicesat es este

[@pitaorj]

Sorry about the dumb question, but why having a single speed cassete and using a 7 speed derailleur?

[@DonnyTerek]

It is simply for keeping the tension on the chain. Other than that is serves no other purpose. There are chain tensioners that you can use instead of a derailleur like I did, but mine did not fit.

[@Timurbey35]

Can i do this bike but i prefer 3 whell bike can i do this

[@robertm.6243]

Hiw did you measure the capacitys on all the cells?

[@user-bg4py3bc3t]

Есть ответ ранее.

[@DonnyTerek]

Using a dedicated capacity measuring charger. Like this one: amzn.to/3a4ofL0

[@rhl2macwan]

Ur battery assembly looks complicated how much did u save compared to buying one from AliExpress including the spot welder and the other bits which is in the video

[@DonnyTerek]

I guess I 'saved' 2-300 USD compared to a factory built battery pack.

[@arcticblack3764]

@@DonnyTerek What pre built battery pack do you recommend for a Bianchi Magma 9.2 21" XL MTB frame? My body weight is 75kg and I plan on riding in the city witch flat terrain. I think a 250w motor is enough for the city but I want the biggest battery I can fit in my frame to get the most range for food deliveries. Loved the video! A reply would be much appreciated!❤

[@Jim_Kush]

how (ah battery) we need for 1000 watt ????

[@DonnyTerek]

At least 13Ah I would say.

[@Tomulisss]

Sveikas Donny Terek man regis lietuvoje iki 1000w motorui nereikalingos teisės, bei tokio galingumo pakanka dviračiui tavo manymu nes dabar labai stipriai svarstau rinktis. Būčiau dėkingas už atsakyma.

[@DonnyTerek]

Sveikas! Kiek žinau, dviratis virš 1kW yra priskiriamas mopedui. Priklauso nuo poreikių, bet susisiekimui 1kW pilnai užtenka. Asmeniškai rinkčiausi nuo 1,5kW jei leidžia kišenė.

[@rc12video]

Imagine a RA seeing someone build these batteries in a dorm

[@l.i.k.amiller6307]

it is cool, but i think 1000w is small power. in my handmade electrick scooter 3200w and 60v 23ah battery. please get us more power))) good luck bro

[@DonnyTerek]

Thanks! 1kW is enough for commuting.

[@kareemvitar6645]

My mid drive planetary 48v 40amp 2000w kit reach me 70km/h,with seventh gear on rear freewheel.I can run it with 72v 80amp,6000w to reach me 125km/h.

[@DonnyTerek]

Sounds awesome! Ride safe at those speeds.

[@sharawyaswan6315]

Frage, ist es möglich, den Motor in einen Stromgenerator umzuwandeln, der die Batterie auflädt, wenn sie leer ist, und ich sende Ihnen Grüße aus dem Süden Ägyptens

[@hohenrover5002]

Das geht wohl nur bei getriebelosen Nabenmotoren. Die meisten sind mit Getriebe.

[@warrenwhite6159]

that battery build is nutz but why did you number the batteries

[@DonnyTerek]

Those are capacity measurements of each cell. Necessary to do for best balance between the cell groups of the battery.

[@E-BikingAdventures]

Why wouldn't you have put the bms where it was suppose to go instead of melting the plastic battery case?

[@DonnyTerek]

It doesn't fit.

[@E-BikingAdventures]

@@DonnyTerek . It doesn't fit where you put it even more, hence the melting. If you put it in the recessed area, you would have only needed to melt it a little bit near the front.

[@DonnyTerek]

@@E-BikingAdventures I would actually need to heat the case even more if I were to place the BMS in the recessed area. This would cause a chance to burn through the case and would look really bulky with the front sticking out.
