It sounds like they sold you defective cells. I thought Headway destroyed and recycled the 25% of cells they manufacture which are faulty / don't meet spec. But I suspect they onsell many of the poor cells in the hope the customer is "none the wiser".

The question is if they are new cells why did you receive them "new" and only measuring 1.5V?

It is a custom made product made to the requirements of the end user. We will supply it in component form since some people may not require all of the components that make up the entire system. For example some people may decide to use lead acid batteries to start with and upgrade to lithium at a la...

We are launching our new product in the next few weeks (as soon as I have the first unit finished). This product is our new “lithium self contained off grid solar/wind power battery cabinet”. This is the first unit which has been made and is the prototype unit. We will be manufacturing these for off...

That's a real e-chopper!

It still looks ok. It triped the fuse and earth leakage detector. Now it just makes a click from one of its relays no other signs of life. It is a Kingpan KP14410KL. Kingpan refuse to supply any circuit diagrams(trade secret!). Not at all happy with it. If the charger is less than 12 months old you...

Saturday was the first test run of the electric boat "Juana" on Sydney Harbour. Juana is a classic sailing boat built from Tassie Huon pine. It was out with the dirty diesel and in with the quiet, eco-friendly AC electric motor. The motor is a 48V 7.5kW Bellman/Mastervolt AC motor drive and is power...

They do show a discharge graph plotting cell voltage vs capacity @ 10C. Take it with a grain of salt but on the graph the cell voltage maintains around 2.9V. Yeah I did see that but 1.5mR does seem over zealous. So are you anti-Headway Rich? What do you consider the overall quality of the cell to b...

For a charger, Brusa is the best IMHO but also very expensive. You can get them from metricmind.com - the NLG513-SX is US$4,396 (price just went up). Apparently LiFeTech is also bringing out a charger shortly - don't have details myself. Yes correct, the Brusa charger is acknowledged as being the w...

That is quite normal and to be expected if the cell are from a Chinese battery manufacturer/company. Are they a reputable brand or a no name cell? You have to be very careful when buying cells from China. I received a few 26650 "A123 cells" which I was absolutely, positively guaranteed they were gen...

....he said this will double the acceleration or range I might be inclined to agree, but not both as "and" implies. I agree. It might increase his range but not nearly double. Considering it has no bodywork, glass etc - so is really light - extra batteries will substantially increase his weight so ...

We also have a Prius PHEV conversion kit. Our kit provides up to 100km range in battery mode with our 9kWh pack. We have supplied dozens and dozens of these kits to customers in the USA and I might be bringing a few to Oz soon since lately I am receiving some enquiries from councils.

In the meantime, yes I meant Ford EV's on sale in Australia and the US. The Focus is in pre-production with demonstrators now scheduled for release in August. in the US, Ford also build the Ford EV Transit Connect Van, and a variety of specialist commercial vehicles. Ford also built an EV Ranger an...

Really now...are you sure about this? How much would you like to bet on this?

Marcopolo, I am not here to tell lies. Everything I say is the truth and you will see this over the coming months as this information comes to light. It is frustrating not being able to talk in detail about some of these fascinating projects since I am sure many forum members would be extremely inte...

I commend them in trying to break into the big boy territory, but until they are producing their own designs and body panels, I’m sorry but I still see it as a conversion. I wish them well in trying to crack it in the big time. Just curious but what is the car manufactured as a Blade or a Hyundai o...

A large part of the car is Australian product since all of the steel Hyundai uses to make their cars comes from 100% iron ore mined in Australia.

That still does not answer my question about my Sachs power assisted pedal bike. This is designed as a proper pedal bicycle with a ICE motor rated at 197W. It is a very high quality bike designed and built in Germany and would last a lifetime if properly maintained. It is not some cheap bike made in...

From the way I read section 2.12.1 you can use your little DC converter modules to charge a separate 12V battery which is supplied power from the traction pack.

Looks like your project is coming along nicely there. I can't see where you fit the 12V battery to run the auxiliary low voltage circuits? I assume you have a hidden battery compartment for this which can't be seen in the photos? I don't have one - scroll up and you will see the power supply I made...

OK fair enough. But we are in Oz and not Obama Land so we need to go by the Oz regulations.

It was very roughly equally divided, with a slight majority switching their DC/DC, some running it continuously, and the minority not using a 12 V battery at all (and hence running the DC/DC all the time also). So it's not unheard of. Personally, I'd switch the DC/DC, but that's just a preference. ...
