CALB Buy - Closed

Fair Enough, I will take you at your word. People should still consider some things before they enter into bulk buy agreements: - CALB does't offer a factory warranty. In my business I have to take that on. - CALB has a significant lead time on orders at present due to large orders from Chinese EV m...

CALB Buy - Closed

For those of you interested it is worth contacting me also as I have a bulk order currently in process and have been importing CALB batteries for some time now. This is deja vu for me as the same thing happened when I started importing Thundersky, a bunch of non-profit (or rather loss-leader) vendor...

Will NiZn be better option for EVers?

Nickel Zinc batteries have been around for a while. There used to be a company making large format 12V NiZn batteries for marine applications. Don't recall the name. I think the issue with them is the cycle life is about the same as lead acid 300-500 cycles or so. Also the energy density is not up t...

Home grown BMS ideas !

Tuarn, The circuit is irrelevant. There are a hundred circuits to achieve the same method. The fact is it is not your original BMS idea or method and you know it. Though given your love of endless circular discussion I don't expect you ever to admit it. Another fact is you came looking to purchase L...

Home grown BMS ideas !

The fact is Tuarn, it was not your idea or original method and you know it. I had done more than a years worth of R&D before I spoke of it at that meeting in 2008. I faced criticism that the system would not work and friendly advice that there were many better systems just around the corner. However...

EV Driving Styles

Congrats Barry. It is good to see another EV on the road. 1) Pulse and go is the go. ie get the vehicle up to speed then coast as much as possible. 2) Next to nothing. 3) Charge LFP batteries at every opportunity. They don't have a memory but the results of over-discharge can be very bad indeed so i...

Hello All, Believe it or not I have only just read this post. I had no idea Tuarn Brown (acmotor) publicized my emails to him about my patent. It does explain a few things about this forum to me. The patent was a costly experiment on my part just to give me some time to develop and comercialise the ...

AC Proton Jumbuck

Thanks Woody.



Unfortunately the motor/controller was a sample order from a big company, Unite Motor. The price was very reasonable, about the same as a good DC system. However their MOQ is 100 units, a bit beyond my financial capabilities.

A123(alike) 20ah pouches

Just for good measure here is a graph of nanophos at 1C and 7C (not 8C as on the graph). FYI 7C = dead flat in 8.5mins. Not many applications require this.
Methinks I'm doing you a big favor Cell Man!

A123(alike) 20ah pouches

I have done an independent test on these cells comparing them to Thundersky and Sky Energy cells. All the cells were fully charged before testing. For the purpose of comparison I put two of the 20Ah nanophosphate cells in parallel to make 40Ah and compared to SE40AHA and LFP40AHA cells at 3C or 120A...
