    New Triangle Battery "Box" Design

    They do make UV fiberglass but sorry I meant to say bondo is what I used on top of the reg. fiberglass. iirc a can this size was about $20. I got it at Canadian Tire, it shouldn't be too hard to find elsewhere...

    New Triangle Battery "Box" Design

    If you want some flex to the design, or shapely inside to your box check out UV fiberglass. Spread it out in the shade then drag it into the sun to cure. Just like reg. fiberglass it has a sweet spot in it's curing time to sand then sets up really hard but remains flexible. It might be smart to...

    New Triangle Battery "Box" Design

    For fiberglassing over cloth I've always just used old t-shirts. But I only buy the cloth and matt and use a super-hard 1:1 marine expoxy for resign. Get a roll of shrink wrap for wrapping skids and do the whole area on the bike you want to glass. Stretch the tshirts over and secure them. Cut...

    Ebay A123s

    I ordered some of those for replacement cells and got verification that they are the same cells Cammy-c V-Power has been using who has mixed reviews with rarely anyone getting full capacity in a prebuilt pack with bms. Hobby King is selling them with tabs attached which is nice but more $...

    Shorted a cell in multi-cell LifePO4

    New cells arrived yesterday!! Has anyone used conductive epoxy for a job like this? I searched and JB weld won't do it but I'm trying to source an epoxy like this today; http://www.directindustry.com/prod/master-bond/electrically-conductive-epoxy-adhesive-17407-198093.html Any draw backs. I...

    Shorted a cell in multi-cell LifePO4

    I already thought so but they look like the same cells to me. Looks can be deceiving though :?: F is the only marking on them.

    Shorted a cell in multi-cell LifePO4

    Ebay seller was more than resonable and made a special buy it now option with my ebay name right in the title. They are on route. I found an online how to on soldering these together. I've also found numerous quotes saying not to solder the ones without tabs. I'll have 2 extra to mess up, wish...

    Shorted a cell in multi-cell LifePO4

    Got 2 replies from CammyCC He confirmed that they are the same cells offered from US seller that they've always used. He did offer to replace "the bad cell" Here's what I don't get is he asked if I could charge the battery without the bms? I didn't think it would be possible to revive a cell...

    Mighty Volt sure when I pull them out. I'll take some better close up pics and measure them but that sure looks similar to me.

    Shorted a cell in multi-cell LifePO4

    I wouldn't expect him to replace them without charge, since it was my own fault here. Ebay seller above got them from CammyCC VPower and offered a price of under $60 for 15 and could I have them in days. I never thought for a minute they were A123, that's a US based company with nice cells I...

    Shorted a cell in multi-cell LifePO4

    All cells in this pack are 3.1-3.2 volts but the last row (where the black ground wire is attached) which is showing 0V on all cells in that row. There doesn't appear to be damage to it or the bms (no smells, burned wire...). I haven't tried to recharge it yet, just short initial top up when...

    BIG PROBLEM: Poor wire size and China products

    In China consumers generally don't demand quality items. They want the latest greatest thing and then junk it for the next one. This attitude is slowly changing as the middle class grows. So if an American company contracts production in China to thier specs you will get higher quality from the...

    Controller Wiring question

    After a few strong but short rides I am also having this problem. I have good reason to believe I have a bad cell but keeping the faith and testing it on a scooter this weekend. Question though I adjusted my controller to 40% output for only about 15A and brought top speed setting to 80% and...

    Watt meter placement

    Ditch my advise on the top bar. I'm moving mine because I've hit it twice with my leg gettting on and off in the few short rides I've done since putting it there. It's worth the few more inches to get it onto the bars, ride and learn I guess.

    Build your own CD battery tab welder for about $100.00+-

    It was my understanding that was to bring the esr down, but yeah I'd rather have a little one explode if anything. So I fig a 6F cap with good esr rating wouldn't stress. None the less HLabs claims they have regular customers on the .5F but still have 70 units. They will sell 4+ @ $30 ea plus...

    Ordered from CammyC on ebay - was labeled with V-Power sticker 48V 15Ah model. Got mine for $325 incl. expedited shipping (at extra $50). Shipping was more than battery closing at $132.50. Not pretty up in there, indeed. I used the same black duct tape (Home Hardware) but I'm worried now...
