    Has anyone used this type of Lithium Ion Battery Charger Li-ion Li-Po

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

    https://www.ebay.com/itm/Lithium-Ion...53.m2749.l2649

    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

    https://www.ebay.com/itm/Lithium-Ion...53.m2749.l2649

    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?
