This makes sense. Yes, it would be possible. You could wire balance connectors and extra discharge plugs to make three packs out of your one 13s pack, such as two 6s packs and a 1s, or two 5s packs and a 3s, etc. Then you’d charge each one, one at at time, using your imax B6 charger. It would take a while, but that’s how you’d do it. Just be careful to not get your connectors confused, as you’ll have three sets of balance wires and three sets of discharge wires.

If you want to test cells from different vendors, the best thing to do is run them through a discharger, preferably a fancy graphing one, and preferably at a high current rating close to the maximum discharge rating. Fake cells are lower quality and won’t be able to provide the same capacity, and will have a larger voltage sag under higher loads.

Regarding the cell question, its a mixture of both. Cheap ebikes use cheap cells. You can bet the Sonders ebike had the cheapest cells available. Name brand ebikes usually use Samsung cells, but sometimes LG and occasionally Panasonic cells can be found in name brand ebikes (the Panasonics are some of the most expensive and so they are rarer). That being said, I’ve seen some shadier internet sites selling high quality (and genuine) Samsung/Panasonic packs, and I’ve seen some nice ebikes with some no-name cells. You should always check with the vendor/manufacturer if you want to ensure you’re getting good cells. Unfortunately, it can be hard to verify the cells yourself though without voiding the warranty, as they are usually sealed under shrink wrap. A good vendor will be happy to confirm the cells for you ahead of time and may even be able to show you some pictures of opened packs to verify.

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.

Lipo batteries are currently the “hottest” battery choice for electric bike enthusiasts. LiPo batteries are the most power-dense type of  battery available to electric bike riders today. The problem is that LiPo battery packs for e-bikes are hard to find, especially one with high output if you are building a racing bike for riding off road.

There are two main types of motor to suit different riding styles. The durable, “heavy duty” Direct-Drive motor, and the lightweight, efficient and fast “performance” geared motor. Electric Bike Motors, hub motors in particular, and electric bike batteries are what make electric bicycles go. Using a hand throttle you control the flow of electric current from the battery to the brushless motor. With an intelligent 20 Amp controller regulating the…

Yes, that’d work, but I’d get an additional 7s battery so you have 20s total. Also, you should know that the older your original 48V battery is, the more time it will take your new 72V combined battery to balance, as the first 13 cells will likely have less capacity in comparison to the newer cells. I made a video recently showing how to do this upgrade that you’re talking about: https://www.youtube.com/watch?v=9KHo-T74IWA

Hi Paul! I enjoyed reading your words and envisioned myself riding along rural streets and gravel roads with beautiful clouds and sunsets. Cycling is wonderful… but I can empathize with your desire for some assist. I got into this because of a knee injury, I wanted to keep the fun and freedom of cycling without the knee sensitivity developed over the course of longer climbs and more regular riding.

GNG now has a different version of the mid drive where the belt reduction (prone to failure) has been replaced by a gear drive at the end of the motor. Has anyone tried it? You can’t argue with the price, but what’s the quality and longevity?

This step is somewhat optional. You should seal your battery somehow to prevent it from shorting on all of that exposed nickel, but it doesn’t necessarily have to be with heat shrink wrap. Some people use duct tape, plastic wrap, fabric, etc. In my opinion though, shrink wrap is the best method because it not only provides a largely water resistant (though not water-proof) seal, but also provides constant and even pressure on all of your connections and wires, reducing the risk of vibration damage.

BesTechPower makes some of the best BMS’s in the industry. You pay for that quality, but I believe it is well worth it. I haven’t used that specific BMS you linked to, so I can’t give you specific feedback on it. I haven’t done very many 7s packs, as that’s on the lower end for ebike use. The few I’ve done had some cheaper BMS’s and not the two wire design I mentioned. Sorry I don’t have any specific recommendations for you – it’s just a lower voltage level that I don’t often use.

If you cannot find the bike you’re interested in here, please contact me and I’ll do my best to track it down, shoot some videos and add it! New videos are regularly added to my YouTube Channel here. Have fun and ride safe 😀

If you buy one of these kits I strongly suggest you spend the extra batteries for e bikes and select a kit that’s big enough (650W or larger) that it uses an external controller. Even if you only need a lower power level, the high powered motor will be more reliable than its smaller Cyclone counterparts. This is because the lower-powered kits have the heat of the controller and motor inside the same housing. Read this entire ES forum thread before buying…it’s a great buyers guide to the Cyclone.

I like to cut most of my nickel strip in advance so I can just weld straight through without breaking my flow to stop and cut more nickel. I measured out the width of three cells and cut enough nickel strip to weld the top and bottoms of 10 sets of 3 cells, meaning 20 strips of nickel that were each 3 cells wide, plus a couple spares in case I messed anything up.

A123 is a brand name of lithium ion phosphate battery used in many EV even full car applications.. A123 cells are known to be of high quality and capable of having high-amp discharge rates with long life expectancy of over 1000 charges. They can provide large amounts of power and have been used in racing applications as well as electric car builds. Chrysler has chosen to use A123 cells in their electric cars.

Have a plan on where you are going to charge your bike before settling on a battery chemistry. If you live in a crowded apartment building and the only place you have to charge is in your living room floor, you may want to decide against any of these lithium technologies.

This new kit uses the same motor as the GNG. It also uses the same basic configuration, with a quiet belted primary reduction in the high-RPM half of the drive, and a narrow and strong chain in the lower-RPM half of the drive.

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 🙂

The bike was more than happy to run and pull me along as long as the throttle was kept very low (<~30%) but as soon the throttle was turned more or I came across a slight gradient uphill the system would cut off (no lights or power). I then have to plug the battery into my charger to 'reset' it before I can then plug it back into my bike and make it work again. I have to keep the throttle low whilst I am riding on the bike before it cuts out but if the wheel is spinning freely in the air then I can max out the throttle and make the motor run at full speed. Some individuals have lost considerable amounts of weight by using an electric bike.[60] By making the biking terrain less of an issue, people who wouldn't otherwise consider biking can use the electric assistance when needed and otherwise pedal as they are able.[61] This means people of lower fitness levels or who haven't cycled in many years can start enjoying the many health benefits E-bikes have to offer. [1] For 12V applications, such as 12V power tools, 3s is the standard. That gives 11.1V nominal and 12.6V fully charged. 6V is trickier, and I imagine you’d have to go with 2s. However, when it comes to charging you should ONLY use a commercial lithium battery charger. Don’t try to use a stock SLA charger – it won’t work for lithium. You need a very specific voltage to reach full charge on lithium (4.2V per cell) and you need a constant current, constant voltage (CC-CV) type charger to ensure safe charging. This is all done in the charger. The BMS only monitors the cells and also cuts current during charging if something goes – the actual charge voltage and current is handled in the charger. 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. You’re absolutely right that doubling the capacity of the battery by running two packs in parallel will essential halve the load on each pack, but I still don’t think it would get it down to the level that you could rely on compression fit spring contacts to safely carry that current, let alone the balance issue of not having the 4 groups individually paralleled at the cell level. 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. Get around in comfort and style with everyday riders from ProdecoTech. Whether you’re commuting to work or riding around town, we have an eBike for you. ProdecoTech American electric bikes can help you save money on gas, save time with your commute and arrive to your destination without breaking a sweat. When we add the fourth parallel group, we’ll again hot glue it in place in the opposite orientation of the third parallel group (and the same orientation of the second parallel group) and then weld it on the opposite side as we welded between the second and third group (and the same side as we welded between the first and second group).
