Aftermarket 5Ah Li-Ion Battery packs for DeWalt, Milwaukee, Makita power-tools | A look at the BMS 

Hey Guys! These aftermarket battery packs are all brand new, just out of the box - fully-charged.
I'm sure many of you have the same question that I have. That is: Are the aftermarket packs safe to use? Do they have a proper BMS inside the pack? Are they reliable?
In this video I opened up 2 packs from different suppliers for the Makita cordless power tools.
It's hard to tell by just looking at the advertisements and/or the given description or pictures because they don't talk of the BMS at all.
