Is it safe to use IMR cells in low current applications?

[Brian321]

I have did alot of reseacr but cant find a answer to this specefic question.

Is it safe to use AW IMR in all low current applications?

I want to buy some more rechargables but not sure if i should stick with RCR's or not( I would rather not).

I will be using the IMR's for jetbeam 3m, Dereelight MCE/XPG drop ins, Surefire with KL1 Head, Jetbeam RRT-0

Thanks,
Brian

It is safe to use IMR cells in low-current applications, but it is more advantageous to use protected regular LiCo instead?

The whole reason for the LiMn chemistry to exist is to provide more current at a cost of capacity (measured at lower currents).

To be fair, IMR cells also have the advantages of a safer chemistry and (IIRC) more charging cycles over the useful life of the cell compared to Lithium Cobalt cells. Extra current is only one of the advantages of IMR cells.

One concern would be that if you don't have a protection circuit you could discharge it pretty low (in a low drain application) without knowing it, and damage the cell.

They should be fine so long as you don't over-discharge them. In a highC application you will see visible signs of dimming. In a lowC, low output application it will not be as visible.

If you plan on running the cells till' they poop in a battery vampire, I would stick with primaries or protected 16340s.
