I wouldn’t say incompatible but us 220 uses the full phase peak to peak of both legs of the elec drop. European and others uses a half phase (I believe) where zero to peak is 220v. Have you had a chance to look into this for me as my welder and box of new 18650’s are sitting idle waiting for me to start welding. Thanks

Thanks for the article, Court. I’m researching so much it feels like a part time job! I have a morning newspaper route that is about 22-25 miles and I would like to start using an ebike for the delivery, as weather permits. According to your article, I’m not going to be able to escape a compromise on some level. If I understand correctly, the constant starting, stopping, and slow speed adjustments could be taxing and uncomfortable with a geared hub. I’ll post my unique situation in the forum instead of hijacking this space.

The Panasonic mid-drive motor is a remarkable bit of engineering. The basic motor design has stayed the same since the early 90s, when Yamaha and Panasonic began building drive systems for pedal assist electric bicycles. What has changed dramatically is the battery technology, which has allowed the Panasonic drive, which since the beginning was extremely reliable, to get better and better, offering riders more power and better range per charge. Today Panasonic remains a top-tier electric bicycle drive manufacturer being spec’d on a wide range of bikes from companies such as Kalkhoff, Focus, Raleigh, KTM, Helkama, and BH Easy Emotion.

Now you’ve got all the info you should need to make your own electric bicycle lithium battery pack. You might still need a few tools, but at least you’ve got the knowledge. Remember to take it slow, plan everything out in advance and enjoy the project. And don’t forget your safety gear!

22f cells are quite low capacity and not very strong. They will work for an ebike (and are about the cheapest good quality cells out there) but they aren’t optimal. You’ll end up with a larger and heavier pack as compared to more energy dense cells like Panasonic 18650pf or Sanyo 18650ga cells.

I’ve been building a 13s6p Li-ion battery based on your article, and everything went swimmingly (except underestimating the amount of nickel I’d need) until I started hooking up the BMS. I was in the middle of hooking up the sense lines, and the BMS smoked. Opening it up, it looks like a few of the caps that couple adjacent nodes burned. Have you seen this before? Any thoughts on what I may have done wrong, or does this just happen sometimes when a cap’s voltage tolerance is outside spec?

It seems like there’s a lot of options out there, even on individual bikes…better batteries, better components, etc. Where’s the happy medium for a price-conscious, street-riding only, out of shape blind guy?

I’ve been reading a bit about how Batterybro.com makes sure to test there batteries are genuine, and how it seems they still get a lot of fake batteries from China. When you buy on Aliexpress.com how to you know and make sure the batteries you buy are genuine? there’s a lot of sellers how did you find yours?

The first pedal-assisted bicycles appeared in India in 1993. In 2008, the sales of e-bike sales exceeded moped sales. In recent years, 2-passenger and even 3-passenger (two adults and a child) e-bikes were introduced in India.[73]

Hi Danl, that sounds like a very high power motor. Most consumer ebikes are in the 36V-48V range, so if your motor is advertised as being rated for those higher voltages then it’s definitely a more serious motor. If you’re looking for a ready-built and relatively inexpensive battery, then something like this might work for you, though I haven’t personally used that battery. You can of course build your own battery just like I did in this article, and that way you’ll be sure to get exactly what you’re looking for. The AH’s required will depend on the quality of the battery. A batter rated for higher current will require fewer AH’s than a lower quality battery. I’d aim for at least 20AH, if not more on a motor of that size. It’s going to eat your battery quickly, so you’ll want more capacity to be able to ride longer.

Well, you’re right that I wouldn’t recommend it! I admire your ingenuity but there are a couple big issues with this setup: 1) You have 4 groups of 10 series cells but no way to balance between them. The 4 cells need to be paralled before they are wired in series otherwise they will get increasingly out of balance with each charge/discharge cycle. 2) I’m not sure you’d get a good enough contact from a copper spring or busbar that is just held on the end of the cells in compression. The copper will also corrode over time and caused increase resistance at the point it touches the cells and problems down the road.

@Charles Avent: This is an easy problem. You need to overspec your motor controller. ie: If you have a 500W motor, get a controller capable of handling 1500W. The larger controllers will have more power mosfets (the electronics actually handling the power to the motor) and more heatsinking. This shouldn’t cost you any more than about $200. People selling quality upgraded controllers will also usually advertise having replaced “no-name mosfets” with quality mosfets with a “low RDS” (ask them about this, if they don’t know don’t what RDS is don’t buy from them, if they do know they’ll be able to solve your problem).

It’s all good Ben, choosing an ebike based solely on the motor is tough because the strength and design of each motor varies. I wouldn’t avoid geared hubs just because there’s more potential for wear over time. I just tested one today that is 5+ years old and still going strong (along with the battery pack). I’ll look for your post in the forums and try to help out if you provide your height, weight, terrain and desired budget 🙂

Hi Craig, here’s a full comparison of the Thron with the ST2. In addition to suspension, the Thron has a better weight distribution given the mid-motor. The ST2 has more fancy smart phone technology and self-updates from the cloud (not sure if that’s online in the US right now). Both are great bikes and the price point is very similar. I’d love to hear your thoughts if you end up with one of these 🙂

I`m trying to figure out a system that offer the less drag possible when pedaling ,but can assist me if the dogs chase me or strange person in the road appears. I don` t mind pedaling heavy weights 250 all include ,what really bother me is the drag .Can you point me in the less drag direction ,and assist power.Thank you in advance.

Hi Court. Thanks for your prompt response. Based on your input and further consideration I have narrowed my selection down to three Bulls e-stream brose MTB models: Evo 3 29er, Evo 3 FS 27.5 plus, and Evo 45 FS. I selected Bulls for a variety of reasons but I have to admit I am a pushover for good looks. Bulls offers a wide range of models and there is a dealer in PA within a reasonable drive from my home in MD. Unfortunately, they do not stock any MTBs but may be getting one or two in soon I can test out. I am still on the fence with regards to a full suspension bike but I realize my back is not getting any younger and I may learn to appreciate the extra comfort on the paved and unpaved hilly roads I ride. One of the suspension seat posts you suggested would definitely help with the hardtail but these are heavy and fast riding bikes (especially the EVO 45 FS which you reviewed in February) so if comfort is of prime concern a full suspension probably is the way to go.

But having read through the document mostly, not completely, I simply stopped reading further due to incorrect usage of words and many bad spellings, some of which would not be caught by a spell checker – “table” for “stable” for example.

Next, plan out your cell configuration on your computer or even with a pencil and paper. This will help ensure you are laying out your pack correctly and show you the final dimensions of the pack. In my top-down drawing below I’ve designated the positive end of the cells in red and the negative end of the cells in white.

    Many people are tempted to use cheaper 18650’s sold under names like Ultrafire, Surefire and Trustfire. Don’t be one of those people. These cells are often marketed as up to 5,000 mAh but struggle to get more than 2,000 mAh. In actuality, these cells are just factory rejects, purchased by companies like Ultrafire and repackaged in their own branded shrink wrap. These B-quality cells are then resold for use in low power devices like flashlights where their weaker performance is less of an issue. If a cell costs less than $2, it simply isn’t worth it. Stick to the name brand cells, like my favorite Samsung cells, if you want to build a safe, quality ebike battery.

    You can also add a label or other information to the outside of your pack for that professional look. If nothing else, it’s a good idea to at least write on the pack what the voltage and capacity is. Especially if you make multiple custom batteries, that will ensure you never forget what the correct charge voltage for the pack is.
