How would the bike fair in wet weather?

[ajovideo]

It wouldn't fair!

And at the TT the scruitinears asked the team to cover the batteries and associated electronics for safety reasons. They used gaffa tape and plastic board.

At that speed on the highway.. how much power did you measured (amp and volt )?

and how many Wh / km?

thanks

For this test, only 2 battery packs were attached. (1/4 of the final number)

1st run, the motor was drawing too much current from battery. It caused a very high discharge rate of 8C continuous. LifeBatt cells are rated at 5C, so the cell voltage dropped below its critical point and the battery management system shut down the bike to protect the cells.

for the 2nd run we reduced the avaiable power to the motor. Average 100A, 68V, 6.8Kw for 12km. Pack had 40% left when we

returned.

weird i thought they were 12 c? rated

this is from there website

LifeBATT modules are rated for continuous discharge at 12C. The pulse rating is 14C and peak rating is 20C !

[ajovideo]

Speaking to Paul today, he said that LifeBATT do several versions of battery, and some of them do have a rate of 20C, but on this bike they chose to use ones with a lower discharge rate.

[rainstormaeroponics]

thanks mate i did wonder

cos li-po batts can do 30c

and are lighter

but i guess lifebatt are your sponsor with lifepo4

there a little behind lipos at the moment

Great video and a wonderful bike.Looks strange with so many things missing and it moving so quickly down the road. Change the title of this video and you'll get alot more exposure to your worthwhile project.

[ajovideo]

thanks for the feedback. Good idea to change the title, will do that shortly...
