    How to rebalance a 4S5P LiOn battery

    Thanks Actually it did eventually balance on the B6 - took probably 60-70 hours. I thought it would cut out after 180 minutes because of the safety timer but I think in balance mode it just keeps trickle charging until the cell is full. The cells are now within a couple of hundredths of a volt...

    How to rebalance a 4S5P LiOn battery

    I have a 160Wh V-lock battery that has somehow got out of balance (the manufacturer is claiming it is the PAG charger I used - don't ask me how, but I guess it's possible that he charger simply isn't compatible with the protection board installed. I do have a sep V-Lock charger that I purchased...

    JP spot welder

    You do realise that is only a 1.5 amp hour pack. You need 10 in parallel to make a 15Ah pack

    Gear derailleur issue

    Thanks Zoot It does have a hanger, in fact it is nearly identical in construction to the orignal derailleur (itisn't a removable hanger). I guess on the bike it came off it attached to the frame lower than the axle. The original derailleur did have a longer hanger and actually bolted into the...

    Gear derailleur issue

    So it is part of an eBike, but I guess this is a more genral request for help on a rear deralleur system. I know a lot of folks here areactually good bike mechanics as well :D I've "modifed" an old Altus derailleur of a Trek to fit my old steel framed bike. It shifts quite well on the stand...

    Bosch Fat packs, Headway, or A123 pack for 36v BMC bike?

    It's the BMS that limits this - I've spoke to EV Components and they suggest 2 packs in parallel (20Ah to get around this..). The cells inside are the same but solder tab raather than screw on type. To the best of my knowledge these are all the new gen cells. The BMS in mine is limited to 20...

    Do you ride your ebike at night?

    Personally, I don't care how obnoxious the monkey electric things are. If they help visibility from motorists at night they have my vote.. BTW - you can program these things - perhaps it should just say "don't hit me!". I emember reading somewhere when they did a safety study side on collisions...

    48v ~ 99volts, green time controller 4110

    Good luck Kentlim - thanks for your help so far on my Cyclone build. Sorry to hear about your problems with the controller. My 900W controller which is rate at 36V 35AMPS actually looks a little beefier than your 1000W model. Note the two x 5W ceramic resistors - I don't know if this is...

    Need help with CA throttle override

    Hi all - I'm trying to setup the throttle override wth the Cyclone motor controller. I'm trying to determine where the resistor that is in series with the throttle might sit. I've taken a photo of the relevant connector inside the controller. I can see one SMT resistor and one normal one. I'm...

    Chainless DD ebike - this system any good?

    Sure - my post wasn't really about price, I was just interested in the driveshaft system. As I pointed out earlier in the thread you can get a quality Trek Soho with exactly the system you describe and electrify that (and they've designed the belt material from the ground up out of some carbon...

    Chainless DD ebike - this system any good?

    Yeah aren't eBay ads wonderful examples of language slaughter.. Originally I emailed this guy because the ad said "free shipping" in the copy, but there was a $US200+ postage fee in the item. His response was to change the ad and send me an email saying "Hello There They are one shipping cost...

    Chainless DD ebike - this system any good?

    Mles is right - this is a front hub motor design :) So I imagine the inefficiency comes from being some kind of worm gear design? Thanks for the clarification. So cleaner and quieter, but heavier and less efiicent than a chain. I'm not a huge fan of front hub motors so it probably isn't for...

    Chainless DD ebike - this system any good?

    Hi - ran across this ad on ebay.. http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWAX:IT&item=260427301258 Looks interesting although the seller has a pretty ordinary reputation. I'd not seen this system on a bike before (eBike or not). The gears are limited but I imagine...

    Aluminium battery enclosures

    Hi all, Been building my own eBike and I eventually settled on the cyclone 900W 3 chainring kit - it's been slow cause I'm rebuilding an old bike and a lot of things are non standard. Anyway - I'll post some vids and pics when I'm finished, but I'm just wondering if anyone has a source for the...
