Hi all,
I've spent a few years piecing this electric cafe racer together. It is (was) a Honda XR100 kids dirtbike. Took 3 degrees out of the headtube, KX100 forks, '78 Yamaha RD350 tank, '76 Honda CR750 superbike tail, SV1000 handlebars, ZX-7 rearsets/footpegs. Registered and insured in Louisiana, then converted to electric. Currently running 4 Zippy 5Ah cell packs in a 2s2p config so 48v and 10Ah (getting 5 miles range, 52 mph top speed). Have been planning on using 6 or 8 of the 8Ah cell packs for 48v, 24/32Ah.
I am not the smartest man and have flushed a lot of cash down the drain buying, and destroying, Lipo's for it and other projects. Noticed Hobby King has these big 8.4ah Lifepo4's:

1. These are rated at 30c which is way over what I thought that chemistry is good for.
2. These are much lighter than other Lifepo4 batterys.
3. They are way cheaper per Ah than all other Lifepo4's. (this one is understandable, the HobbyKing effect i'm guessing)
So, anyone have any experience with these? Anyone have any thought or comments on using these?
I'm pulling 300amps max, using a ME0708 motor and a Kelly KDZ48401 controller.
Cheers - Travis
