Open source controller

Hi Woody, Yes you are right one of our OZ group had blown two of the OZ controllers I don't know what caused his to blow. Apart from him I have blown two through my own fault and AVOLT has blown one through a mistake so it seems that if you want a good digital controller at a good price you have to ...

I have tried a amp hour test today, I drove normally ( not aggressively) at a little over 80kmh on country roads, then repeated the test on the same road driving conservatively up to 60kmh, for the 80 kmh the result was 1.495AH per Km and for the 60 kmh test it was 0.98AH per Km. So allowing for my ...

I will post the temperature results when I have done a good test over the weekend, so far I can see no problem with open source. My Curtis blew up after it ran out of warranty.

Anyone interested in building a controller, I have just received 100 mosfets that I had to wait almost three months for to get a good price, I still have 70 to spare. You require 10 per controller. They cost me $7.00 landed.

Jim I don't know of anyone in Brisbane with Li-ion batteries. If you contact Ian of ZEVA in W.A. they seem to be the main importers for Australia. We are still working on the cheap controller, I will email everyone who has enquired when it is up to the stage of ordering. I have found someone who wil...

Jim
Have a good look at the size of the Li-Ion batteries, they are fairly small and quite light compared to Lead acid. You may not need to lose the back seat of your Barina.

For anyone interested in Li-ion batteries I did a test today on a run to our local shop. 18 km round trip used 22.83AH therefore my 90AH pack should go 70.96KM , in the summer I was working it out at 75KM, I don't know if the drop in Kms is due to the batteries being one year old or the colder weath...

Re generator size. I opted for the simple and safe way, that is I fed the 240V AC into my chargers therefore I could only get 18 AMPS. Probably my 13 hp. 5.5 kva would keep you driving. If you put the 240V through a bridge rectifier to convert it to DC then the battery pack should accept this as wha...
