Yeah I think a whole meeting with Tuarn devoted to setting up AC systems would be the go. No no you NEED the gearbox to do the wheelies! Highly wrong to unbalance a car - would be a cool show car at the drag races - maybe in a couple of conversion I might give it a go! What car you putting this in? ...

Noisey controllers

Had a P plater pull up along side me in his ute the other day he had farm animal noises coming from under his bonnet. I guess it was a cheap way to get those extra horses under the bonnet. I happened to have a cd in my car with a song on it called "the wild life" so I put it on and turned it up. I g...

TS lithium is around USD$2.00/Ah. The smaller ones and bigger ones cost a bit more but not by much. Try not to compare kW for motors as it can be a bit misleading. It is not really a direct comparison as to the performance you will get. It is better to look at the Torque specification of the car. Th...

Yeah I suggested someone should make up some catchy stickers for eV's. "Someone stole my exaust system" "Sorry I'm out of petrol too" etc .... Thanks for the info. I had brief visions that is was root 2 times 2. That'd be alot of batteries! I kind of suspected though when reading through the control...

Hi Guys, Paul I see your interested in the AC systems. Pls post up prices and details if you find out about the Blade systems. Also I doubt you will need the 160Ah battery though. Remember a typical car would only consume 150Wh/km@80km/hr. So 100*3.2V*160Ah=51200Wh. With 80%DOD this is 40960Wh. 4096...

Would probably work well with the "CAT" bus system in Perth. They have a short set route around the cities. They could use the fast charge technique on electric busses. btw electric busses are already made and are running in other contries. Would just need to be modified for a fast charge system. On...

EV wiring help

Hmmm. The problem is that every model car is different and every person uses different eV parts so almost all conversions are different. So there would be no one guide that could give a step by step instruction to help a novice complete thier conversion. As I/others suggested in your other post cons...

72 volt motor choice?

Umm I'd be more concerned about buying a motor where they don't even publish the full specs. Are you buying it just because it has regen? I haven't done the calcs but 72V with that motor maybe pushing to get 100km/hr. The torque seems on par. You would probably need more than 72V for the speed what ...

Yeah that'll go good! Don't forget to take lots of photos. If you can't read schematics well enough to do it yourself I would also recommend the help of an auto-electrician.

Heating for a 72V conversion

Yeah don't run you a/c backwards! Nichrome/cuprothal too much of a fire hazard so don't use that either. Although if a bug makes it that far in the vent it deserves to fry! If you are concerned that a 1500W heater will only give you 600W and is not enough why not use 2? Heating the existing core sou...

Heating for a 72V conversion

could always run your aircon pump backwards!
2nd thoughts better not do that - unless you know its gunna work.

Air heaters are just nichrome wire - you can buy it at tricky dickies!
Turn you A/C button into a toggle switch AC ON - BOTH OFF - HEATER ON.

Most batteries are rated to how many cycles they expect over thier life. SLA are rated around 500-1000 cycles. So if you used it 5 times a week 52 weeks a year it would last 2-4 years. How far you can go depends on how big the pack is. If you want a 30km round trip then you buy the pack size to suit...

Don't think so. We could look at it from another perspective. Lets say he could get 185Nm at the back wheel continuous up to 100km/hr. This is a force of just over 600N at the wheel. Taking into account the bike + rider this is an acceleration of 2.63m/s^2. So to get to 100km/hr this would be about ...

I agree it is a nice setup you have planned. However I was just reading your blog. What "250cc performance" do you think you will get? I was looking at a Ninja250 which does over 600Nm at the wheels in first gear. So a Mars@300A is about 33Nm so a gear ratio of 18.2:1 gives you the same performance....
