Lithium Ion Battery Charger Li-ion Li-Po 3.6V 3.7V 4.2V 3A

I have one that is 8.4 volts and it works pretty good it does let you know when it is done charging
These battery charging switching power supply almost always use the cheapest no brand name capacitors they can find really give me a break

I bought this charger because I have a lot of batteries that I just bought I want an easy way to fast charge them after I have slow charge them a few times frist and yes I will be using a BSM board on them

Here is the way I cycle them

I frist charge them slow
Second I load them at 1.5 amps unit the BSM board cuts them off
Keep repeating this until I get the same running time results

Then put them on a battery charging analyster amperage hour reading

Here is the inside of this switching power supply

The voltage with no load 4.21 with a 860 mill amp 3.98 volts
The switching power supply will start with a 12 volt 20 watt light bulb hook to it

Of coarse it had no name brand caps inside of it

How well would you say this switching power supply is made

What is the P/N of the charger controller IC on the cold side, if it is charger controller?

M358 this is what I can make out

I am thinking it is a LM358
