I have a homemade battery made up of 84 NCR18650b cells that I bought (in other words, I didn’t make the battery myself). Anyway, I lost the charger for it at Burning Man, and now I’m going nuts trying to figure out what kind of charger to buy. The arrangement of the batteries is odd. Part of the battery looks pretty straight forward in what I believe is a 8s6p design, but the rest look different… they are set up like a 4×3 rectangle framed by 2 L’s. I would have happily uploaded a picture, but that doesn’t seem possible. Is there anyway I can send you a picture to show you what I mean?

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.

Hi Court, great site and appreciate your insight, and obvious care. I am also ebike noobie, but have been doing my homework (hours of googling). Personal specs are, old guy, out of shape (5′ 10″ 270# but physically intact), looking to “upgrade” self. I am a mechanic for living, so nothing technical worries me. You have done great job of laying out the general parameters and options, so now I “get” that, and have evolved to the confused info overload stage. Application would be recreational/touring, hills/long grades are always in play, some trail riding, but no serious mountain biking at all. Range not so much a big deal, and plan to “pedal” for the exercise, assist would be for hills, and overextending (needing a lift back to the barn). Issues for me are quality/durability, and rider stability including push off and simple shifting (as opposed to complicated timing and planning routines). I may also see a fair amount of urban stop and go when vacationing etc.I don’t see myself speeding along at 30mph (scares the bejeebers out of me to even think about that speed on a bike). Lots of questions, but will focus on one … It seems like most of the issues (other than battery, range, regeneration and such) revolve around drive train concerns. I like the idea of the mid-mount, but am concerned about the shifting and stress on chain etc. Can a quality mid-mount add on kit, easily work with an internal shifting rear hub. The idea being simplicity…no front shifter, single cog, and easy rear shifting (especially when stopped, or going slow). I am a little confused over the internal geared options, seems like several methods Including external gear set for more increments). Problem may be the shifting while motor engaged. But I believe the internal shifting (similar to the old 3-speed bikes) can be done while pedaling or not, so likewise would not be affected by motor load. If true, that reduces the need(benefit?) of a motor disengage feedback when shifting. This setup also seems like it would benefit from a torque(? not sure I understand this) aware feedback mechanism (seems cadence ones are not really so great) for the “assist” with a few selectable assist modes. If not applied to an external geared internal hub, then only 2 cogs now, and perhaps can use the gates belt system, which seems like a good (dependable) upgrade (not sure how well gates deals with hard shifts if that is a concern). Anyways, hopefully I have asked a reasonable (as opposed to ridiculous!!) application question. If viable, could you suggest the actual brands/models you would use? Thx again.

Wow, that’s a really interesting way to do it. So their auxiliary battery connects to the charge port of the primary battery, which means it’s not actually powering the bike but rather just charging the primary battery, which then powers the bike. Not the most efficient way to do it, but it’s simple and elegant.

Hi Micah, I have been studying your how to build an bike battery, and enjoyed all the tips. I have been having a bit of difficulty figuring out the wiring portion of the construct however. For example, you talk of C, B and P pads and wires you solder to the top and bottom of the pack; the yet don’t put arrows to or refer to their colors for easy identification. The charge and discharge instructions for connecting are gone over rather fast with little for us to identify with exactly where to attach to, etc. Could you revisit your post here and include some baby steps for those who can’t follow the reference instructions you give for wiring the BMS?

– BMS/Greenbikekit are now selling cased or shrinkwrap LiFePo batteries based on high capacity cylindrical cells probably from Headway and with a BMS. These have a higher C Rating between 5C and 10C. This makes a 48v-10AHr battery useable in a high performance kit with 30-40A max. Using this with a 1000W-1500W motor/controller should work fine. This is heavier than LiPo but close to the holy grail. Long lasting, safe/easy/convenient, high power.

” Electric Bicycle I purchased from you guys has been outstanding. I have had it now for almost 1 year and I use it everyday to commute to work 2 miles from my home. Everyone at the office always comments on how great of a idea I had. I also bought one for my 2 son’s and one for my wife. Electric Bicycle folds up easily for transportation in my car so I can take it with me everywhere I go. ”

Next comes the heat shrink tube. Large diameter heat shrink tube is hard to find, and I got lucky with a big score of different sizes from a Chinese vendor before his supply dried up. Your best bet is to check sites like eBay for short lengths of heat shrink in the size you need.

Hi Miran! The Pulsar 250 watt hub motor sounds decent, for your short commute it could work fine and in my opinion front mounted hub motors are alright for basic city riding. They can change the steering dynamic and handling a bit but with a small motor like the one you shared I don’t think it would be a big deal. I really like the Bafang mid-drive but that will be very fast, powerful and possibly illegal where you live. Also, it might be difficult to install compared to the front kit. Here is one I reviewed that might be similar to your Pulsar: https://electricbikereview.com/clean-republic/hill-topper/

I’ve gotten so many different BMS’s from so many different suppliers so I’m not 100% positive, but I believe it was from this source: http://www.aliexpress.com/item/NEW-Battery-Protection-BMS-PCB-Board-for-10-Packs-36V-Li-ion-Cell-max-30A-w/32291193643.html

The sense wires generally connect to the positive of each cell group, but sometimes there is one more sense wire than parallel groups because the first sense wire is intended to connect to the negative of the first cell group, then all the subsequent sense wires connect to the positive of each cell group. Each BMS should be labeled on the board to show where each sense wire goes (B1-, B1+, B2+, B3+, etc…)

Hey Court – I would have replied sooner but I wasn’t notified you had replied, guess I will have to check this site more often. I never thought of a front drive system before, I will check it out. From what your article said, I think I can still pedal and probably need to to go up a 8% grade. I like the idea of being able to simply detach the battery and the hub when I put it in the boat. I am going to look around for a more powerful motor as I need to get it up to closer to 28 mph if possible. Just did the ride yesterday and let me tell you the whole way I was like, “need that ebike NOW” If you have any other thoughts let me know….. Thank you, Eric

An electric bicycle, also known as an e-bike, powerbike or booster bike, is a bicycle with an integrated electric motor which can be used for propulsion. Many kinds of e-bikes are available worldwide, from e-bikes that only have a small motor to assist the rider’s pedal-power (i.e., pedelecs) to somewhat more powerful e-bikes which tend closer to moped-style functionality: all, however, retain the ability to be pedalled by the rider and are therefore not electric motorcycles. E-bikes use rechargeable batteries and the lighter varieties can travel up to 25 to 32 km/h (16 to 20 mph), depending on the laws of the country in which they are sold, while the more high-powered varieties can often do in excess of 45 km/h (28 mph). In some markets, such as Germany, they are gaining in popularity and taking some market share away from conventional bicycles,[1] while in others, such as China, they are replacing fossil fuel-powered mopeds and small motorcycles.[2][3]

If you buy one of these kits I strongly suggest you spend the extra money 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 http://electricbikemotor.net 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 don’t think there is any danger to parallel more than 4 cells. Tesla cars have literally hundreds of 18650 cells just like these paralleled. The issue is that if you ever did have a problem with one cell, like a factory defect that caused it to short circuit, it could die and drag all the other cells down with it, killing the entire parallel group. That’s why Tesla uses individual cell fusing, but that’s not really employed on the small scale like for ebikes.

Hi Vincent! In my opinion, there are a whole bunch of great possibilities out there. Luna has high powered stuff and the BBSHD worked great for me when reviewing a Lectric Cycles conversion a year back (using their e-RAD kit). Of course I also like BionX but the stuff is more expensive and proprietary. I’m doing less conversions these days (at least review wise) so I’m a bit behind on the category. For me, the frame makes a big difference and depending on what sort of terrain I’m encountering I’ll lean towards hubs for smooth and zippy feel or mid-drive for better climbing with the understanding that it might wear my drivetrain down, especially without shift sensing. That’s one area where e-RAD and maybe Luna now too, have some good options and accessories.

Some e-bikes have an electric motor that operates on a power-on-demand basis only. In this case, the electric motor is engaged and operated manually using a throttle, which is usually on the handgrip just like the ones on a motorbike or scooter. These sorts of e-bikes often, but not always, have more powerful motors than pedelecs do.

The main limitation of those holders is power – they can’t handle it. For a few amps, they might be fine, but ebikes require dozens of amps, which would surely melt those guys. Think about it this way: professional ebike batteries have big hunks of nickel plate welded between cells. The tiny little spring contacts of those holders will never compare to that kind of current carrying ability.

Hi Sundaram, I’m not aware of many 18650 LiFePO4 cells, are you sure you are using that chemistry instead of standard lithium ion? Perhaps can you provide a little more detail about the specific cells you’re using?

  1. Gotcha. Can you recommend a manufacturer that sells a two wire version? Maybe I can look around their products and see if they sell any 7S cells, rather than sifting through all the manufacturers on Alibaba. Searches for “2 wire MBS” didn’t yield much. Thanks again for your help with this!
