all components have already arrived, so this should progress fairly quickly.



components list:

Excellent product list,wheres the battery going?

 

[ridethelightning]

well, i was first going to use a pelicase on the front, but as the cells were in cell holders, i couldnt easilly fit all 200 in there, so i scrapped that idea.
also was not keen on the affects of the huge weight on the front when negotiating traffic at low speeds for instance.

so its to be 200x200x~70mm blocks saddling over toptube behind the steerer, in leather cases.

its not that stealthy or smooth but at least the weight is in the right place(ish), and fairly compact.

here is a pic of a similar build in russia, also gt idrive

I'm not going to tell you that the Pelican on the fork is the right option, but it definitely worked out well for me with an identical battery configuration. I negotiate slow traffic constantly every day and after the initial learning curve the steering is very controllable. That being said my next bike (more like motorcycle at this point) will have a centralised battery position. If you can achieve it, it's probably going to be better.

i like the peli for the waterproofness and good protection, but with the way my cells were welded in 10p strips, they just wernt going to fit in a 1300.
i considered teslanv's kilowatt bag, but it wasnt idealy shaped for the purpose and shipping was a killer from u.s.(im down in kangaroo land here)
so this what i came up with-

and heres a few more..

I like the top tube panniers they look snug and it will keep the batteries from getting jostled,easy removal is a great option,unless your a thief .

bike is nearly finished now, will post more shots soon.
im now learning the ropes of doing phase wire and temp sensor mods in cromotor
here im using 8awg turnigy silicone wires, black gasket rtv silicone and the kty83 temp sensor that came with adaptto.

this is actually another cro i had lying around with the longer axle im using to practice on, then ill do the one on this bike.

 

[ridethelightning]

so im not too sure if the high temp wrap is necessary at the joint to the windings. i havnt got any so i might use fibreglass cloth and rtv silicone there..
other suggestions welcome!

i actually just cut the wires for the other set of halls, so as not to clutter up space in the axle. i can always get in there and replace the broken hall at some stage and re-join the wires.

oh, and i noticed that although ther are 2 set sof 0v and +5 wires, they are actually wired together in the motor, i guess so you can just swap them if one of the wires breaks somewhere...
