i thought the ICR didnt need protection because of the different chemistry just like the IMR (also known as High Drain) and the specs ive seen show the ICR and IMR to have similar energy densities and perform much better then the regular li-ion batts.
i cut open a dead IMR and no circuits. i have not cut open an ICR that i have but mine are identical to the IMR so not gonna be any chips there either. but there are so many kinds of batteries out there now its hard to be sure whats what.
