I don't Harry, though someone who has opened their case may know
.
To be honest though, I can't see that performance would be (much) different from the existing Li ezee batteries, and at 4.5kg its quite heavy and not as cost-effective or reliable as NiMH, which weighs only fractionally more.
Another quote from the manufacturer in an email reply to an enquiry about discharge rate and voltage sag for a 24V 10Ah battery:
Quote:
The 10AH pack for your 250W motor is enough.
The standard discharge rate is 1C = 10A
You test 22.5V at 15A is normal.
But we do not suggest to have too high rate discharge , since that may reduce the lifecycles.
We can make 12V pack, but 12V pack is not so popular , we have 24V, 36V, 48V pack .
The capacity can be 10AH , 12AH, 20AH .

So its a battery rated for low power use: 'standard' discharge meets less than 2/3 of e.g. a Torq's peak power output, and only half that for an f-series bike.
I wonder if other LiFe batteries are any better (why does it seem that powertools use decent quality Lithium batteries, but they're not available for ebikes??), but at the sorts of prices & weights these ones are, it just really doesn't seem worth paying any more for them than NiMH, especially given the uncertainty about performance & lifetime.
