    A123 Batteries

    I have 24 20ah prismatics available for sale. They are full tabs. These are not the garbage cells like you see for sale now that have cut up/welded tabs. It'll be about $800 (shipping, etc) These are ones from a project that never came to fruition. After the initial rush of sales, the...

    Hobbit hal needs help on choosing path for gen1 insight

    You have a lot of options. The charger Peter came up with costs less than $100 to build, and may help you limp along for quite a while longer. Mike's is awesome and extremely configurable, but pricey. ($1,000 with all the goodies) I'm not sure where you are located, but I could certainly...

    How much is getting tested & matched A123 20ah cells worth?

    Although I am not the longest-running member of this site, if needed, I am interested in helping with the coordination of this cooperative buying group. I've worked with obtaining and distributing A123 cells from other successful group buys and can be verified as a real person (not a sock...

    La Free E-Bike Trouble shooting

    For my bike, in the end we removed all the fancy electronics. We replaced them with a used throttle and motor controller and tied directly to the motor. Way less complex and easier to troubleshoot.

    La Free E-Bike Trouble shooting

    I own a similar-ish bike that LaFree made called the Ford Think Bike. As part of my research on the Ford Think I ran into lots of LaFree stuff on the web. I made a google site about all the stuff I found, and on there I have links to some LaFree resources...

    A123 20AHr Pouch Cell Battery Build & Info Thread

    Butt splices you linked to are not the same as the one in teklektik's post. Cost is much different. I notice that even on the butt splices there is a 500 piece minimum order and they do not stock them.

    A123 20AHr Pouch Cell Battery Build & Info Thread

    I've been down the termifoil path guys, and they require a minimum 2,000 piece order. Price to the consumer would be about $1.25-$1.50 per connector. Also there is a 12-14 week lead time. I'd do it, but I'm not sure I'd ever be able to recoup the money. Anyone wanna' go in on it with me? (Half...

    Purchasing from ShenZhen Victpower Technology

    Can you elaborate more on this? Are you using wire transfer or Payal? Are they saying there was a spelling error or anything like that? Any sort for timeline of events would help clarify.

    CellLog 8 hacking

    First, thank you so much for the pdf. I knew it must be possible, but didn't know how. If you do come across the pcb design someday, I'd love to see it. Great work and thanks again for sharing!

    CellLog 8 hacking

    I am very interested in this circuit. Was the schematic posted somewhere? I actually need it for 7, 12v cells in series, but hopefully there would be a way to adapt whatever you have already done. Thanks in advance.

    Dr.Bass Steveo found 7s3p Module! Awesome Price!!

    So here is the type of usage I'm considering for buying these packs http://www.roperld.com/science/SunRoperTrips.htm You can see in the third graphic down, that there can be some high-current draws. (290a, 250a, 225a, etc) I'm not sure three 7s3p packs will be able to handle the load. The...

    I thought these cells had a resting voltage of about 3.3v?

    Dr.Bass Steveo found 7s3p Module! Awesome Price!!

    The problem we have is when someone outside forums like ES blindly buys these packs without doing any research. They expect 100% error free, brand new cells, and as we all know that is not necessarily the case. Perhaps the price could be lowered even more if we chose to accept them "As Is"...

    Dr.Bass Steveo found 7s3p Module! Awesome Price!!

    For those keeping score at home who plan to try to take apart the packs ... this works out to about $26.45 per cell. A bit more than the last group buy ($24.57)( http://endless-sphere.com/forums/viewtopic.php?f=14&t=37955 ), but possibly more work to take everything apart. This works out to...

    Dr.Bass Steveo found 7s3p Module! Awesome Price!!

    I'll be watching this thread closely. I'm looking at this for hybrid car or small EV applications. It would be helpful to know some of the dimensions, especially the 42s3p. To provide more flexibility of configuration, it might be easier to be easier to do six of the 7s3p instead. (But would...

    ford think bike

    Well, I brought the voltage on the battery up beyond 24 V. Now up to ~25.8V, and guess what.... 3 LED lights show up on the power meter and the bike runs as it should. After speaking with a great electric bike shop he told me over the phone that he's seen these bike's batteries be up in the 28...

    O.k. already have a dumb question. Anyone know how to remove the pedal crank so that I can get the plastic side panels off? EDIT: Google turned up this... http://myweb.tiscali.co.uk/flecc/motorunit1.html Looks like I need a crank extractor tool. Great. This is a bike similar to the Ford...

    ford think bike

    I have spoken to an owner who had a local electric bike shop that wired up a generic throttle/potentiometer and bypassed the stock monitor and now he is able to ride his bike without even using pedal assist. I hope to find out enough information about his set up to do the same thing. I am...
