Or Keeppower saves the premium circuit for the premium brands and the little less (but still very) good ones for budget brands like IO.
I guess you are gonna receive the one from IO? A comparison with the unprotected one would be really cool though.

That theory does not fit.
I will call the performance of these two batteries virtual identical.
The lowest trace (i.e. the 5A) is the best to see differences in protection.

Yes, the 5A trace is different but the capacity is the same. So that would be a different PCB. Why doesnt my theory fit then?

The 5A track is the same for the two batteries, except at the start and that has nothing to do with the protection.

Okay. So there is a difference in the cell?

That dip at the start might be due to temperature (The cell need to heat up a bit, to get full performance), my testing lab does not have a tightly controlled temperature, it will vary a few degrees.

Any known fav lights that these positively won’t fit in? I know Hi-Max’s won’t fit in 501Bs, but I’ve not seen too many batteries that are so big that they don’t work in most lights.

The diameter is to large, but they do fit in length.

I would expect there are many light, but I have not tested.

I think fasttech has them in stock though. I ordered a set a week and half ago and just got them. Got another set coming in.
Again. I. Advance I apologize but if I had to pick between the keeppower black 3400 maH protected or these Panasonic 3400 maH protected which is a better performer?

I have these Batteries, they are a tight fit, but they fit both the TN30 and TN31.
