D Lithium rechgeable 3.7v 7500mah-Feeler...

I'd be in for 2 so long as they are protected.

 

[jimjones3630]

At that price range...at least 5.

 

[Argon]

I would be in for three if protected.

Be good to know the brand and if they have a credible set of run time curves at various amp loads. When it sounds too good to be true (compared to the ones JimmyM was looking at)....it might still be true. That's more than twice as expensive as Emoli or A123's...but if that mAh is right, it's actually a good deal.

If they are in the UK I don't mind doing some discharge curves on a CBA-II...

I'm in for two to start off with.
I was kinda hoping that AW would come up with some D size Li-ions since he mentioned that he would have a D size soft start but so far no mention?

 

[frogs3]

Depending on reliability, I would be in for 4, esp. if JimmyM could be persuaded to build a few extra mosfets.

Just think of the hotwires that would have decent runtimes!

[ergotelis]

Me too for 3-4 batteries, great price!

 

[flex76italy]

Any chances to see the spec from the web?

 

[plasmaman]

I expect to have a few samples for testing in the next couple of days, so I will post more info then.

Can someone propose a meaningful and useful test programme I could run on these cells to produce a helpful runtime/discharge graph? I have a good DMM, and lots of hosts/bulbs.

One should be sent to someone who has the CBA-II like Tom uses for all his battery shootout profiles at various amps....so we can see how it behaves under various amp loads, and get printouts.

If Tom (Silverfox) would do it, everyone would really appreciate his opinion. DMM readings are nearly worthless without under load tests, and doing a custom lamp load test will not have the standardization that the CBA-II provides.

I bought one of those units, but am not as experienced with it yet. They are damn sweet though.

Has our dollar fallen below the 2:1 ratio? My God, what things have come to.
Soon it'll be like the old Peso.
Waiter: Can I help you?
Customer: A small Coke, please.
Waiter: That will be $67,000

20GBP, which is a touch over 40 bucks.

Still want 10 though.

Don't worry, the US $ is still worth a bit more than the Zimbabwe $.

1.00 UK Pound = 2.03 US Dollars (when I last checked)... great for the UK buying from the US but much more difficult if we are trying to export!

With UK taxes and the exchange rate - things are almost 1/2 price now when bought in US dollars.​

Bump...

 

[elnino]

I would be interested in a few depending on the price.

I may be in for 3...(I need more details)
which charger do you suggest?

 

[benyosh]

At least three for me.

I'd highly recommend a balancing charger. I use the Bantam BC-8. It's expensive, but has built-in balancing of up to 8 cells.
There's a 4 cell balance-charger on all-battery.com

How does this sound for a possible application: 4 cells in a 4D Mag with an Osram 64623. At 14.8 volts nominal, it should outshine a 12-cell NiMH setup, depending on how well these cells stand up to the load. Runtime might be around 40 to 45 minutes... Better bring your oven mitts!

Or maybe 5 cells in a 5D Mag with the Osram 64458? Might be "underdriving" it a bit, but again it would last around 40 minutes. I wonder if it would be possible to actually melt the head? Nah...
