The point being that once you go past 4.2x, or give it a severe shock/impact, you're holding a grenade in your hand, the pin is pulled, you just haven't released the yet. But the the detonator is not under your -control-, it's a chemical reaction that will light up sooner or later.
Ok, i'm scared now!!
So by this, tell me what's the best way to charge a lipo battery.
I've followed this topic: Battery charger - General Electronics - Arduino Forum
Do you think i'm ok with that?
cjdelphi:
I ended up building my own lithium ion charger circuit using simply 5v, arduino powered.
It looks scary for me 
do you have a schematic and the source that you can share with this community?
It would be awesome.
Also tell me, can you charge any kind of lipo battery (i have an idea that each mA need a different situation)?
polymorph:
I think there was a misunderstanding and the OP connected his meter set on Amps directly across the battery.
Well, yeh
