EV on eBay

not as easy as it is to convert an ice one to electric.
some of the EV Ravs on ebay are converts rather than OEM.

The adapter plate of the US version is the same as over here.

Electric Yamaha FZR-E Conversion

yes, hydrogen has many properties that arent friendly towards engines. Its less stable (much much lower octane, around 40) so its far more prone to predetonation...its on par with putting diesel in your fuel tank. Of course this problem can be overcome with correct tuning/modifications. Hydrogen als...

i dont know of any motor between the etek 15hp peak units and the 6.7" series wound 72hp peak. If you go for a smaller motor your efficiency will suffer, as will your continuous output. The continuous output of the 6.7" is 16hp, if you go to a smaller motor you may run into heat problems. Heres a li...

The lithium cobalts do handle deep discharges alot better yes, come to think of it. the service life of a lead pack is approx 3-500 cycles @80% dod, and lithium cobalt is suposed to 500 cycles to 80%. LiFePO4 is 2000 cycles to 80%. I think you will find Ni-MH is more expensive than lithum nowadays. ...

Ah the universal requirement "But it has to go like hell! That part is not negotiable!" lol That motor is a series wound DC motor.

Hi derek, If your getting lithium, dont worry about power limiting, they way you describe it, your setup couldnt even approach their limits. regarding LiPo packs, their service life isnt much better than lead, but they arent that much more expensive for such a small pack. a LiPo pack for you applica...

as far as doing it healthy, i would say so, rod dilkes pulls 450A out of his 90AH (also 5C) pretty regularly in his conversion. his pack is now a year old and going strong. Most i have pulled out of my pack is 250A (just over 6C) and it sagged to 2vpc. The thundersky batteries seem to be pretty cons...

re thunderskys,
I use thundersky lfp40 on my bike (48v pack), and they meet specification.
their voltage under load is closer to 3vpc though, so if your looking for 72 under load instead of 72v nominal, you need 24cells.

Hi Andrew, how far do you normally ride each day? Could you use extra range? are you riding the scooter until low voltage cut off? are you leaving the batteries in a partial state of charge for more than 3hrs? its strange that the batteries are failing after just 750km. If your doing any of the abov...

yes i had (have) a similar experience with my budget, i too started with $25k, but now ive had to push that out to $33k. at least if you start out with lead, you will know what the car will handle like with lots of weight, and how usable it will be with just 2 seats. lol you could probably then upgr...

yes, staying below $25k will be a challenge, and impossible if this includes the cost of the donor vehicle. to get 100km range you will need around 20kwh of battery capacity for a car of that size. have a look at http://www.waeva.asn.au/batrun_tutorial.htm in particular, look for a link "spreadsheet...

ah, yes for that, a higher ratio would be better.
looks like a good conversion.
your 0-100 in 16sec target is very achievable.
btw, what kind of budget are you looking at?
what kind of batteries were you thinking of using?
your conversion is starting to sound better and better.

Hi Priit, The warp9 motors aren't meant to be run at 9000rpm. from what i read 6000rpm is about their safe continuous limit. However, with that kind of setup, you wont be able to get to 130kmh anyway. The max voltage you can put across the armature windings without causing significant arcing is 170v...

TESLA not so expensive

in principal i would agree, but im not sure a camry is such a good conversion vehicle. ideally you would pick a vehicle where you could mount the batteries under neath and centrally. you also need something with either a heavy drive train (any iron block v8, a prius, an insight, etc) or decent paylo...

another thing you need to condisder is the difference between gvm and kerb weights. the kerb weight of an mr2 is 1050kg vs 1310kg for its gvm. this means i can add 110kg withou needing to upgrade anything at all. not sure what the stats are for he x1/9, but for most stuff ive found drive.com and red...

whats the greatest mass you can put on a quad? and 6.7" x91 and 144v curtis directly driving a diff would do what your looking for. however the x91 weighs 40kg. make sure you get an x91, not a L91, as the x91 has smaller windings, which are more efficient at lower currents than the L91. Also it can ...

yeh x1/9s are a good conversion car, especially since the engineering in the engine department wasn't all that flash. all x1/9s are late 70's early 80s. If you want something newer try an aw11 mr2. similar sort of deal but mid to late 80s, and toyota, and they tend not to rust. theres another mid-mo...
