    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

    Pros:

    Capacity rather normal, low price, but only under condition of full functionality. The test has shown the return

    Cons:

    Been purchased batteries UltraFire Protected 18650 3.7V 2400mAh Lithium Batteries (2-Pack Grey) SKU 19624. These batteries are equipped with pay protection against deep discharge. I performed a test (for confidence in the future) of the two batteries. None of the batteries are not made unlocking the chain at position 2,7 V. I brought the voltage to 2.4, but the battery went to work. Circuit protection did not work. Voltage drop below 2,7 V is considered to be fatal to the battery. Declared "Protected" are not as!!!!!!Testing tank showed that the real capacity of 1950-2050 mA. Tests were run on 4 batteries

    OtherThoughts:

    Bottomline:

    I do not recommend
