You can buy LiFePO4 straight from China from Ping Battery. These batteries are a little bulky, but are safe, and will last over 1000 charges. You can also buy ready made Lithium Iron Phoshate (LiFePO4) or Lithium Polymer (LiPo) packs from BMS battery.

It says it is 110 volts (220 are available) but this welder needs a 60 amp circuit (breaker) to work properly so it is not advisable to use at home! anyway, have you found this is a certainty? that you must use a 110 volt (single phase) 60 amp circuit? is this what you are using? have you been having breakers flip when you use your welder on a smaller breaker? (most homes are 20 amp breakers) Or would it just be better to go with their 2 phase (220 volt) 60 amp breaker? I guess I could just pick up another breaker and run it directly from the panel.

I don’t actually have one of Lightning Rod’s kits, so unfortunately I can’t comment deeper right now. But I sure don’t find it valuable to just rag on the cost without examining other factors of the component quality and design. Lot’s of owners of the GNG kit went to lightning rod’s dev to purchase upgrade components because of lack of quality on the “cheap” kit.

Court, I have enjoyed reading and watching your reviews of ebikes. I bought a Neo 29er today from a San Francisco area ebike dealer mainly due to your high opinion of Easy Motion ebikes. Dealer gave me a very good price. Hopefully with the battery change on the new Evo BH will continue to support the Neo line.

Thanks so much for the info, that sounds great and an exciting option! I understand the warranty issue but aside from that, you don’t see any issue than with building a battery of any capacity and just making the discharge cable with an xlr connection to plug into the bike. Would I need a different cable to charge the battery or does it charge via the xlr connection like theirs? Here is one more link with a few more answered questions about their auxiliary battery if you wanted more info. Thanks again, this is really exciting, I just want to make sure I don’t fry anything

Four hundredths of a volt is probably fine to parallel them, but I would be more worried about why the cells aren’t all the same. If they are brand new cells from the factory, they should be nearly spot on. These might be more expensive than what you paid, but I get my Samsung 25R cells from this vendor, where I know they’re genuine and straight from the factory, and all come at exactly the same voltage.

Spot welders for batteries aren’t the same as most home spot welders. Unlike the large jaw spot welders for home workshops, battery spot welders have the electrodes on the same side. I’ve never seen them for sale in the US, but they can be found pretty easily on eBay and other international commerce websites. My full time use welder is a fairly simple model that I got here. A highly recommended source for a slightly nicer spot welder design (pictured below) with both mounted and handheld electrodes can be found here.

Lithium Battery technology in a bicycle is still experimental and you have to use a lot of common sense when using these batteries. However with a little education and some end user carefulness, you can use lithium batteries safely, the same as you can safely deal with putting gasoline in your riding lawn mower.

I have seen as much as 8000 watts going through a traditional derailleur gear chain (see astro ebike story) with little problems as long as shifting is done with care….but that is with quality shimano components and chain.

The new Electric Bike Kit Owners group on Facebook has taken off within the first week of its creation. Around 400 people have joined the online group with new members being added every day. E-bike riders are sharing the various ways that they have converted their bikes using the E-BikeKit Complete Electric Bike Conversion System. Each one of the electric bike conversions is more unique than the next. Some e-bike…

Gaston is an admin and key contributor at the popular Endless Sphere Technology Forum Batteries and battery packs, the lifeblood of your electric bicycle Plug and play?… not always that easy and certainly not very simple for most of us.. or is it? A good Lithium battery pack can cost as much, and often even more than the rest of your electric bike kit. Picking the right…

Duke Eco-Marathon Team using an Electric Bike Technologies hub motor for the 2014 Shell Eco-marathon. The E-BikeKit motor provides optimal space saving because it does not require a chain (this makes it great for converting road bicycles to electric bicycles, which is what it is designed to do) but we hope to determine if it provides us with a better overall vehicle efficiency than our outboard motor.

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/

Dan has been riding electric bikes almost daily since 2008…

You’ll notice that for my charge wires I used larger diameter wires than the sense wires that came with the BMS. That’s because charging will deliver more current than those sense wires will. Also, you’ll notice the discharge wires (including the B- pad to the negative terminal of the pack) are the thickest wires of all of them, as these will carry the entire power of the whole pack during discharging. I used 16 awg for the charge wires and 12 awg for the discharge wires.

We are pleased to announce that ElectricRider is currently undergoing some major modifications. Many of the products ElectricRider has manufactured for years will soon be provided by a new company whom we’ve selected for their fresh perspective, strong morals and desire to serve the high performance LEV market. We will provide further updates and information here as it becomes available.

To reach our intended voltage of 36V, we have to connect a number of 18650 cells in series. Lithium-ion battery cells are nominally rated at 3.6 or 3.7V, meaning to reach 36V nominal, we’ll need 10 cells in series. The industry abbreviation for series is ‘s’, so this pack will be known as a “10S pack” or 10 cells in series for a final pack voltage of 36V.

E-Tube wires are compatible with 6770 Ultegra 10spd Di2, 6870 Ultegra 11spd Di2, 9070 Dura Ace 11spd Di2, plus all Shimano MTB Di2 and STEPS systems. Shimano’s e-tube technology; e-tube is a two-prong system and is NOT cross compatible with Dura-Ace 7970 Di2 wiring.

So to recap… hub motors operate independently of the rider pedaling, they can be geared or gearless, can fit in the rear wheel, front wheel or even independently from the wheels as with the Organic Transit ELF (though this is very uncommon) and they can sometimes generate electricity. Some drawbacks of all hub motors include increased unsprung weight, which can reduce traction, limit efficiency and strain spokes and rims. They usually have just one gear setting that can operate at a faster or slower speed but cannot shift for improved torque or speed. They also tend to make wheels more difficult to service (changing flat tires or fixing spokes) because they add weight to the wheel and require extra cables to deliver electricity and operation signals (unless they are an all in one hub motor like the FlyKly or Copenhagen Wheel).

Since you mentioned the charger, the link you sent me came with a 2 amp charger but it would take 10 hours to charge that size battery. Could I use a larger amp charger like 5 or even more for faster charging? How do you tell what is too much so you don’t damage the battery? Thanks!!

Court, great site you have here. I will tell you want i think i want but realize i don’t really know what i am talking about: i am looking for the best bike i can get. i want speed, endurance, great on hills, smooth ride and easy gear change, light weight (but not if it is in exchange for a lesser battery), max battery (48v and 17/18ah, and max watts) and anything else you can think of. i am a little confused on the different systems, but want the best of all worlds (of course) but realize that there will be compramise. maybe you can tell me the best balance of all that i am looking for as i am not price sensitive. What do you think of the Stromer ST2? any other bikes i should look at? c

  1. This is what I refer to “small cells”, the 18650 (cordless tool) type cells which need to be spot-welded or soldered together to form a large pack. The big advantage of these cells is they offer better cooling because of the nature of their shape to the LiPo soft pouches, and therefore have the capacity to last longer.
    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…
    I’m sorry but I’m not certain. Here in Israel we are on 50hz so I haven’t tried that model on 60hz. I do however have some friends in the US that have that model on 60hz. They have been happy with it, but I haven’t used it myself so I can’t say how it compares to my experience.
