  • FAST charger for Li-Ion

    Involvement:General (knows how to use it) - Ownership:1 week to 1 month

    Pros:

    FAST charger.
    It has a charge current of +-1.5A
    It can charge Li-Ion(4.2V selector) and LiFePo4 (3V selector)

    Cons:

    It gets pretty hot when charging.
    No 12V input.

    OtherThoughts:

    Fast charger! measured a current of 1.7A when charging a 26650 4000mAh.

    Be aware what cells you charge on this. Small size (small capacity) Li-Ion can't be charged, as it will charge TOO fast for them.
    At a 1.5A rated current, I would only charge on this batteries that have almost real 1500mAh.

    Bottomline:

    A fast charger for high capacity Li-Ion batteries.
    Charging a good 26650 on a WF139 or similar took too much time. With this charger it only took 3 hours and a few minutes to go from 3.0V to 4.21V.
