Can discharged Headways be saved?

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".

Can discharged Headways be saved?

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

Solar Power and Batteries

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...

144 volt charger needed

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...

That EV grin happens on the water too!

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...

Alternative to Headway cells

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...

Charging a 450V battery pack

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...

Considering it has no bodywork, glass etc - so is really light - extra batteries will substantially increase his weight so ...

Plug-in conversion kit for Prius - NilCO2 kit?

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.

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.

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?

DC-DC Converter Charging

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. ...
