That looks absolutely horrible. I would get all my money back and then some. Shoulda went with konions My Cammy_CC battery is still ok. Im not doing any big discharge rates on mine so its fine for the scooter I have.

I just got some konions in the mail from an ebay bosch fatpack. I havent picked up a charger yet but I was wondering if it would be hard to make a single or double cell charger for these konions? Do they sell double cell chargers for 18650 konions?

SHOW US A TOP SPEED VIDEO!!! IM DYING TO KNOW HOW FAST THIS THING GOES!!!

might as well buy a ping pack I dont know if you noticed but pico1 looks like our friend from Falcon-EV. He's uploaded the same graph that our buddy has on his website. Maybe pico1 is taking a peek at our forums. :) EDIT ADD: Pico's graph at 3C is no where close to Dr.Bass' graph at 3C. Im going wi...

The same Kart was later re-done to eliminate the clutch, and run direct drive. It was much faster, much more efficient, and smokes the tires from a start rather than smokeing the clutch. RC motor speed controllers seem to be shockingly good at starting a motor from a stop, even under load. Don't as...

It all makes sense now. My only concern now is I have no idea how I would mount this to the bike. Can you buy this as a whole kit? When do you expect this to be completely finished?

Can you have a 12mm because 1/2 inch is about .7mm too big for my turnigy motor? Please. :D :mrgreen: The adapters are not for the motor shafts, but for the output shaft of the drive, which is 1/2". It is not too hard to get pulleys for 12mm motor shafts. Plus, you can drill these out pretty easily...

Yup, 1/2 inch.

Hi, The drive itself is aluminum. Steel tabs would need to be welded to the frame to bolt to. Simple enough. Matt I believe the Xtracycle frame is aluminum so I think Matt means aluminum tabs. It is a collar that set screws to the shaft with threads for the freewheel. Piece of cake. Matt So do I ne...

So do I need to get both the FW adaptor and crankset?

I will post pics sometime tonight.

I am very impressed with the quality of these!

How do these FW adaptors work? Do you need to have an axle cup welded to it?

I was thinking of doing the exact same thing for my ebike. The reason that he uses the clutch is because of the high amp draw to get the go kart (or bike) moving. Once the go kart or bike is moving, I dont think that there is a problem. The main reason that the clutch has been overlooked is because ...

Right at about 0:40 when I say "I hate that!" I'm referring to the giant spark that occurs when the batteries are connected to the ESC. What do you guys do to prevent this from happening? I feel like that could wear out connectors quite prematurely. :? http://endless-sphere.com/forums/viewtopic.php...

Anyone ever compare the new Headway cells to the equilivent capacity TS cells? For exampl 4P of new Headways to a TS-40 ah ? The published ratings look similar at 3c. The going rate for Headways looks to be around $20 each, Elite wants $68 for a single TS-40. Headways all the way. The Thundersky ce...

I wired one of Jonathan's shells up to a pack that is 4 18v LXTs in parallel. I just soldered a wire to the each of the terminals on the PCB in the shell. However the charger flashes that the battery is bad after about two minutes. Do I need to somehow disable the BMS board to get this to work? Tha...

This charger will not work for you because they do not have a 36V option.

Can anybody verify the 2ah rating, it seems I read somewhere that it was closer to 1.8? The VT cell is rated for 1.1ah and the Bosch fatpacks are 2p so 2.2ah max in theory. I got a couple used VTs and before I fried my CBA I saw just shy of 1ah under heavy load (at like ~8C... was ~30w discharge if...

Dimitri, So we save a total of $25 each? Minus cost of shipping to whomever does the footwork, sounds pretty good. Are these being fazed out by Bosch, or are they keeping the 36 volt line? I wonder if the price will keep going down. I wanted two chargers so that I could parallel the chargers to get...

The Grand Conclusion This is where you really see the big difference. Check out the heat created: Heat.gif ...and the total heat: HeatTotal.gif The bottom line is that the RC motor just blows away the competition . This should put the final nail in the coffin of the hub motor and makes me want to a...

I was looking on ebay and I saw some Bosch 36 volts going for $59 for the Fatpack which is 2 ah I believe. If you buy 4 and get 2 chargers that should come in around $300. I'm thinking of doing it myself. I was thinking the exact same thing. Im was quoted $50 per pack if I buy 10 packs. Ill take 5 ...

Li-MN for so high discharge rate is not very safe. WoW, 90A constant current, 30AH high rate LiFePo4 can hold it, constant 3C. :D I dont need 90A continous :lol: What Im looking for is something that will give my rc motor a little juice when I go up a really steep hill for a couple of seconds. I wi...

The problem that Im having is making something that will charge quickly enough for my new rc setup so that I can travel to school, charge the battery pack, and travel back. The other problem is money. LiMn is so far the cheapest way to get LiFePo4 and I dont even need a BMS!! Headway cells would be ...

Since $.55 p/wh is not practical, Im thinking about going with a 36V 10ah lithium manganese. I should easily be able to do that with the Bosch fat packs.

Yea I totally missed that.

The life cycle compared to the konions is really bad. Only 250 cycles!!! They must have really been discharging the batteries at currents for their testing.
