OK, first batch of 50 charged.
I have changed my setup a bit. I spaced them out so much because it made it much easier to put together, the magnets are so strong that it is constantly tying to turn itself into a big ball of firey mess.
The downside of this is that I cant pass much current through the nickel strip and I dont have enough to layer t up over that distance.
The strip was hitting about 50 deg C at about 15A. So I spent some extra time and done this:

This lets me put lots of layers of nickel strip to handle the current.
This has halved the temperature of the nickel strip:

Now I'm being held back by the croc clips. they get very hot above 15A and this charger is capable of 40A so I will try and do something about it so I can reduce my charge time. These amperage levels are nothing for the cells, they are all rated at about a 1C charge rate, meaning that this lot of cells can be charged at about 130-140A, so charging at 15A or even 40A is absolutely nothing to them.
These also turned up this morning:

Not so hopeful about these, but they were cheap and I have plenty of good cells now.
:edit: Changed all the croc clips to soldered on 10AWG wire, now changing at 25A, stip is at about 30 deg C. ____________________ Current Bikes:Honda 929RR Fireblade, Honda CD200 Benly (Project), Stomp Z2 140

I like the trick new oversize disc!
Need to get a bigger disc on my Giant, as it's only a 160mm, which is a bit lacking at speed really. |

The bigger disc will definitely help but it's that Avid brake that is the main problem. I have 3 Avid brakes and they're all a bit rubbish once you really get going. For the kind of speeds you're going you should really be upgrading the brake as a whole. I'd look at something like a Shimano Saint or a Hope Tech 3. Yes they're expensive but I'd much rather have something like that on a bike that you'll be zipping around on at 40mph. ____________________ Now: '00 Kawasaki ZRX1100R - Past: '84 Yamaha DT125, '89 Kawasaki KLR600, '97 Yamaha XJ600N

The actual braking force is fine, can still stoppie at most speeds (which I think is quite good considering all that weight at the back). It just has a ridiculous amount of fade.
I'm gonna give these a clean and a good bleed and see how things go. If not will have to upgrade. Cheers for the suggestions. ____________________ Current Bikes:Honda 929RR Fireblade, Honda CD200 Benly (Project), Stomp Z2 140

If you wanted cheap, you could consider some sliding pin pit bike brakes - but chunky and you'd need to make a bracket etc.
But then, keeping adding more weight and you'll need more power. Which will need strong components. And... then you've got a pit bike, basically . |
