3.7v 2600mAh Rechargeable Lithium-ion Battery Replacement for Digital Amplifier

Just received the battery from Amazon, and realized I have no way of telling if this has a protection circuit added to it or not. With so many lithium-ion battery cells now available with a protection circuit already added to it it's becoming critical for manufacturers to specifically note on each model of their batteries whether or not it has protection circuitry or not. Hate having to send something back that I never would've ordered if I knew it were what I'm looking for.

I cant give an honest review yet because the order hasn’t arrived. It has been 8 days since i ordered this and today i see its still in SLC,Utah so it will probably take 10 days to finally receive this. I can say that if you need this in a hurry you probably need to discuss different shipping methods or purchase it somewhere else.
