Battery Vehicle Society

Hey Tim, I stand by what I said that it is misleading and an annoyance but if nothing else it has sparked a debate. I would reply that this site is (batteryvehiclesociety.org) not (sustainable energy.org). There are plenty of sites that are available for sustainable energy but I have never seen a be...

In the General forum there is a topic "Do sheep dream of electric cars" or someting similar. I read the post as it is a fairly witty paraphrase of Philip K. Dicks' novel. I wasted my time checking the link and it has nothing to do with battery vehicles. It is very misleading and in my opin...

Thanks for that Jeremy, you just saved me a lot of money. The motor I was actually looking at before I got sidetracked looking at pence per watt is the Scorpion S-5525-170Kv. I haven't got an UK price for it but from the manufacturer it is $210. This motor is rated as 2k3W. The reason I am asking if...

It's good to see your making progress. How much power do you need from your motor? I am going to be testing the Scorpion HK-4025-630KV. 4 of them should give me about 10kW. These motors are rated as 2k7 W continuous power. They also have a 4035 model rated as 3k5 W cont. http://www.micronradiocontro...

Has anyone got experience of these motors?

I am seriously thinking about trying the HK-4025-630KV. 4 of these should give me about 13bhp which would be enough power for a low performance city quad which is the project that I am working on.

Already thought of import etc, but I didn't have the costs. I can have IR ship to a friend in the states then have my friend post them here. I dont mind having up to 2 times as many FET's as I need because I may end up having 3 or 4 motors in the quad and back of a fag packet calc for the cabin crui...

Hi Jeremy, The best price for the IRFB3077PBF that I could find was based on an order of 150 (they come in packs of 50) from International Rectifiers themselves. There's a surprise. US$2.4 each 150 for $360 Shipping to UK $50.20 Total $410.20 That is not too shabby at all. I was ordering as a guest ...

I would be perfectly happy using the FETs as yourself. When do you need them? I cannot afford to buy the FET's and the controllers at the same time but I am perfectly happy getting the FETs first. Ging to the dealer with an order of 140 FETs has got be worth a reasonable discount. I am glad that you...

Jeremy, Thanks for all that I have had a couple of days making decisions. For the controller I am going with the 18 FET one you mentioned and just as you did they will be unpopulated so I can fit my own choice of FETs. I will order 4 of these as I definitely need 2 for my project and my next project...

Hi Jeremy, I am so honoured to rx my first post on the forum from yourself. I have read quite a few of your posts and I like your style. What you said is interesting can you post links. I am thinking about controller: http://uk.rs-online.com/web/search/searchBrowseAction.html?method=getProduct&R...
