Came across these batteries on Ebay. There made from a reputable company (For some). It seem like a good deal. These are claimed as protected too.
I really want to see some battery guro's test and review these before i buy them.
You don't normally find IMR cells that are protected. The protection circuit would severely limit the current that the cell could provide without the circuit tripping, which would somewhat defeat the object of using IMR cells in the first place. You would be losing capacity in comparison to an ICR cell of the same size, and the more stable nature of the IMR chemistry is something of a moot point when you have a protection circuit installed. So you would be getting the disadvantage of the IMR's lower capacity, but not getting the advantage of the IMR's higher current handling capabilities.
Looking at the picture, it doesn't look like a protection circuit is installed anyway.
Thanks for the info. Good point, I agree they dont look to have PCB.
4800 mAh seems a bit on a high side even for ICR cells, and even more so for IMR. Looks like hugely overrated.
Yes, that was something else I meant to mention, and then forgot after all the talk about protection circuits - my memory is rubbish, and I quickly loose track of my thoughts! 
The stated capacity is high, even for an ICR as stated, so an IMR cell seems unlikely. You would either either be getting an IMR cell, but with considerably less capacity than stated, or an ICR cell with a little less capacity, but without the protection circuit that you would then want to have.
Either way, you're not going to get quite what they say you are.
imr=?
IMR = LiMn chemistry
ICR = LiCo chemistry
Not always true, but broadly speaking, you would expect an IMR cell to exhibit lower voltage sag at any given current draw than an ICR cell, and to handle a higher current draw than would really be safe for an ICR cell. They are also generally safer to handle than an ICR cell without a protection circuit.
The downside is that size for size, the IMR cell will normally have a lower capacity than an ICR cell. However, in the high current uses at which IMR cells excel, this may not actually be an issue. The voltage sag on an ICR cell at high current draw would cause a protection circuit to trip early - before the cell was fully discharged - so you may not get an opportunity to use the additional capacity of the ICR cell. The IMR cell on the other hand will maintain it's voltage better, and run until 'empty', and so you get to utilise the full capacity of the cell. As such, depending on the exact current draw required, and just how much voltage sag the ICR cell suffers, there may be no disadvantage to the IMR cells lower capacity.
