Wow! You have 5300mAh and 6000mAh 18650 cells? It might say that on the label, but if I had such batteries, I’d dump them.

Agreed, no such thing. Typically there are no 18650's above 3400 mAh. I'd only trust cells made by Panasonic, Samsung, and LG. Stay away from Chinese crap. They may end up setting your house on fire.. As far as Chargers, Xtar's are excellent. I personally own several including the VP2.

For the money the LiitoKala 260 and 300 are the best availible, no fan noise, cheap and they have a resistance function so we can gauge how used a laptop pull really is.

PERIOD

for the first step:
MrChip should read a bit about LiIon cells to understand their dangers!

3,7V IS the nomilal voltage of the cells
charged fully is 4,2 Volts / empty around 3V

then read about fakes (mostly “whatsoever”fire with a ridiculus value of capacity)
