I have no idea...as I just replaced the TRF turnbuckles with Lunsford ones.
Try the HotBoddies website for the manual in PDF, find the part number, find a shop - google is your friend. Flea-bay might have them too.
You need to get at least two more packs of cells too - which is probably more important right now.
I noticed you repeaked the same pack 4 times on Sunday and you did it at 8A!!! This is really really bad - you're asking for trouble, especially with those IB4200 (which have been known to explode causing a lot of damage!!!)
.
If you carry on like that it will end in tears for sure. Ever seen an exploded pack of IBs? Not good and very dangerous!

The manufacturers recommend charging at 4A max, most people do 5A, but at 8A you're actually quite lucky to have not suffered a problem yet. At best your cells won't last very long charging at 8A and you'll need new ones sooner, which can get expensive.
Keep an eye on the for sale section on oOple, someone will be getting rid of some that should be in reasonable condition. Or you could post a wanted add.
