As far as dimensions, I prefer to use 0.1 or 0.15 mm thick nickel, and usually use a 7 or 8 mm wide strip. A stronger welder can do thicker strip, but will cost a lot more. If your welder can do 0.15 mm nickel strip then go for it; thicker is always better. If you have thinner strips then that’s fine too, just lay down a couple layers on top of each other when necessary to create connections that can carry more current.

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.

I’ve had good luck with Bulls and Haibike but any frame manufacturer that gets to work with Bosch or Brose is going to be good. Easy Motion has a couple models now with Brose. If possible, try to buy from your local shop so they can fit you and offer warranty support. Do you know what brands they carry? I’d say, pick one based on pictures, special order the correct size and go in to pick it up… when you go, have the shop also order a riser or even rise + swept-back bar and maybe some ergonomic grips. Get a Thudbuster or BodyFloat or the Suntour NCX seat post suspension in the correct size and have them fit you. You could swap tires too but I love riding knobby tires even on the road, they a huge difference on dirt and it sounds like you spend some time on surfaces like that.

thanks for detail explanation , I was enjoj reading it. Well, I am interesting why did you pick this tipe of battery, I was thinking to use LiFePO4, I know there are usualy 3.2V it is less than 3.6V like here? Also, can you explain me how to calculate max current of battery, it says that you get 8.7Ah, but how much Ampers and what is the power of battery, how many Watts (P = U * I)? Furthermore, without welding, can I do on contact connection, like for example are battery in remote control?

Should the voltage on the charger be exact, or can it be *higher* than my battery pack? For example, I need to charge a 19.2V pack. Does my charger have to *exactly match* (or come as close to as possible to) this 19.2V, or can I use a higher voltage charger, (say, 36V)? Will the charger automatically adjust to a lower voltage, allowing a 36V charger to charge my 19.2V pack?

Finally found it. WOW!! Exactly what was needed. I struggle with conceptualizing verbal descriptions. You solved that! With the new JP Welder from Croatia my first welded build will soon be a reality. Thanks for all you do for eBiking!

To determine how much power you need, you’ll need to determine the voltage you want and the capacity you need to supply that power (voltage times current). Read this article to learn more about calculating your ebike’s power: http://www.ebikeschool.com/myth-ebike-wattage/

Thank you for the very informative post, and it has helped a lot. I plan on building a battery pack with 20 cells with blocks of 4 in parallel, and then I am going to put those batteries for electric bike series to make an 18.5V, 13.6A pack. Sorry if these sounds a little bit foolish, but I am not sure what kind of BMS I should be using. Would I be able to use any BMS or would there be an issue with having extra wires if the BMS can power more batteries in series?

Actually I have ran into a problem – a few days ago I was riding it up a hill on a hot day when the power cut off and it wouldn’t start again. When I tried to charge it, the light on the charger just flickered from green to orange. I took out the battery and found that one of the cells had corroded from what looks like overheating. I think that the battery pack failure was most likely caused by too much of a load applied to the battery pack.

If you have time, I’d be curious to hear about the pros and cons of this kind of approach. Is the main drawback simply the cumulative size of the plastic housing? Or is there some other limitation to this kind of hardware that makes it unsuitable?

Batteries Plus Bulbs is proud to be an industry leader in battery recycling. That’s why we have an extensive recycling program to help reduce waste and environmental hazards. Stop by your local store and ask an associate what your area’s regulations are regarding e-bike batteries. If you’re having trouble finding a battery for your electric bike, visit your local Batteries Plus Bulbs store and ask an associate for help. They’ll help you find the perfect battery for your bike based on your needs and budget.

This bike only needs to get me to and from work on paved roads (and some sidewalks) and I don’t plan to ever take it on any trails but it does need to be able to handle hills. I have a local bike shop near me, but they currently don’t sell anything electric (the guy did warn me against Pedego bikes, though…saying they were not good quality. I mention that to say this: I don’t know how good any local service options are going to be for me, so simplicity and having a bike that works are important. Also, I’m on disability and don’t have much money, so price is a factor (that’s why the Flux on Indiegogo appeals to me).

  1. Next, grab another 3 cells (or however many you are putting in your parallel groups) and perform the same operation to make another parallel group just like the first one. Then keep going. I’m making eight more parallel groups for a total of 10 parallel groups.

    It is possible to do it that way, however there are some compelling reasons not to. 1) By first joining all the series cells you would end up with multiple high voltage groups, which means both the chance and consequences of an accident are greater. When you’re working with lots of exposed batteries with nickel conductors and metal tools flying around, the last thing you want is more high voltage possibilities for shorts. 2) Doing series cells first would be come unwieldy, physically. A series group is only connected at either the top or bottom of alternating cells. Without having multiple cells side by side to add stability, a long chain of single cells will need either a pile of glue or some type of physical holder to support the chain. and 3) most battery spot welders can only reach about 2 cells deep into a pack, meaning you’d have to either add very short nickel strips to each series group connecting only two groups (which means twice the welding and twice the cell damaging heat) or have long uncontrolled nickel strips hanging off the sides, again risking shorting.
