@Nailseayts and @johnny_469
I saw in the doc provided by samsung.
http://www.datasheet4u.com/pdf/839321/Samsung/INR18650-25R.html

Charge Current:
Standard current (A) 1.25
Max. current (A) 4.0

I am a bit confused...

@johnny_469
I will keep that in mind and charge them when they are 3.2
Also, should I charge in low or normal mode?
