  1. A123 module charging question

    Batteries and Charging
    Hey everyone! I am currently working on a conversion and spotted these packs for sale on eBay. Now I know the dollar per kilowatt isn't that great on these, but I am trying to keep the costs low, so I plan to start out with a few of these for a proof of concept and then upgrade down the road...

    Parts Vendors
    Hello! I am in China and have a friend who is looking for clients to export batteries to. Any potential buyers here? Next year, I will be buying some a123 20Ah pouches myself for an electric motorcycle project. PM me if you are interested! We can negotiate prices later.

  4. CAUTION about ShenZhen Victpower Technology Co.

    Batteries and Charging
    CAUTION about ShenZhen Victpower Technology Co. The bottom line is that they sent whatever they had on hand, including some totally junk/reject cells, and any guarantee they claim to offer is worthless. I knew I was taking a risk and can accept the ~10% loss but I would caution anyone...
  5. East Coast A123 Pouch Cell Group Buy

    Batteries and Charging
    Can the A123 AMP20 Prismatic Pouch AMP20M1HD-A cells be charged with 4C? The A123 page contains very little information: Nowhere I can find a datasheet of them, can someone point me to one? I only found a page of a German...

    New Member Introductions
    Hi all, I was chasing some internet links around the other day and stumbled upon A123's Developer Kit: If I am reading this correctly you get 6 battery cells, each at 3.3v (for a total of 19.8v) for $129. For $220 you can double that to 12 cells to get...
