    Electra Straight 8 Brake Options

    Would something like this work on the front hub. I guess I would probably have to re-lace my front wheel onto a hub that would be compatible with this right?

    Electra Straight 8 Brake Options

    I just purchase a used Electra Straight 8 to convert to electric. I love the look of this bike. I want to put a bafang BBSHD mid drive system on the bike. I noticed however that the bike only has coaster brakes on the rear wheel, the kind that stop you when you pedal backwards. It has no...

    A123 to be acquired by Wanxiang Group

    Two Questions: 1. Do you think we (the diy hobbyists) will now be able to buy A123 cells directly from the company? 2. Will GM still use A123 cells in their Chevy Spark EV?

    LIPO Cycling Questions

    I'm sure this has probably been covered on this forum ad nauseum, however I cannot seem to find any real conclusive information on the subject. My question is, is it necessary to cycle your LIPO batteries on a monthly basis? I was watching some videos on the Maxamps website, and the guy in the...

    Concerns over A123's viability

    I came across this headline while searching for news on battery technology. I would be totally bummed, now that we seem to be getting some access to these cells. Jerry A123 sees "going concern" risk due to steep losses (Reuters) - Lithium-ion battery maker A123 Systems Inc (AONE.O) said on...

    Sources for Custom Aluminum Cases

Currently I have 6 - 5000maH turnigy batteries for a total of 48V and 15aH. I would like to attach it to my bike utilizing the holes in...

    Bulk Charging Lipo Battery Question

    Thanks for all the helpful ideas... The charger is definitely set the "charge" not "store". When it cuts out, the hyperion does not play the "charge completed" tune, it simply exits out of charge mode. I am using an Alinco DM-330MV power supply capable of providing 32Amps, so I don't believe...

    Bulk Charging Lipo Battery Question

    Thanks for all the replies... I am still having the problem where midway through the charge cycle, my charger just aborts the charge process. It does not give me any indication as to why. Initially, the charger would quit charging and give me a "capacity end" message. I think that is because...

    Bulk Charging Lipo Battery Question

    I have a dumb question... I was hoping some of you experts on the Forum could help me out... I have 6 - 5000Mah 6s 1p Turnigy Lipo batteries that I have been charging individually using a Hyperion EOS1420inet3 charger. Everything works great. I have now connected the batteries in Parallel in...

    Oatnet, Where in SoCal are you located? Some of the Pics looks like Corona Del Mar... That's cool that you have a Vectrix too... Have you posted any Vids of it? I would love to see some pics or vids... Did you lace your own rim on your BMC motor? I'm not sure I would trust myself doing...

    Headway Cell at 1.000 Volts

    I just received my charger from Voltphreaks. I attached one of my Headway batteries that was reading .631 volts. At first when I plugged it in, the read light on the charger was flashing. After about 1/2 hour it turned to a solid red light. It took about 6 hours, but the light on the charger...

    Headway Cell at 1.000 Volts

    I was wondering if there is any way to bring a Headway 10Ah cell back to life if it is registering 1.00 volts. Any help would be appreciated... I was also wondering if the Turnigy (Lipo) packs require a separate BMS when discharging. Thanks! Jer

    Battery/Controller Cutting out

    Thanks for the helpful input guys... I am really starting to think that the BMS is tripping. The bike that is cutting out has a 35Amp controller. Today, I hooked up the battery to my other bike which has a 20Amp controller. I rode the bike for about 7 miles full throttle and did not have any...

    Battery/Controller Cutting out

    I was hoping you guys might have some suggestions regarding this: While I was out riding today, it felt like the controller kept cutting out, and I would lose all power. I tried turning the controller off and then back on, but that did not help. What I finally ended up doing was to turn off...

    Single Cell Chargers - Any Suggestions?

    I just got my headway cells from the group buy. I just want to make sure that I don't let the cells drain too much while they are on the shelf waiting to be built into packs. Does anyone have any recommendations for a good charger that I could buy to charge the single cells individually in the...
