    Exactly: just marketing buzz. Just ignore it.

    Seems contradicting to me.

    Thanks! Or it's time to clean the terminals, or to check with more serious tool... Example from my records: five LG B1 cells (datasheet claims ≤ 70 mΩ) checked with 4-wire Kelvin circuit and with unmodified MC3000: 59.5 == 191 59.2 == 337 58.2 == 198 58.4 == 249 58.3 == 138 It's nice to have...

    Thank you! Main intention was, to minimize voltage errors on discharge. IR measurement in MC3000 is a joke anyway: four-wire scheme is needed to do it properly. But after modding, the deviation of displayed IR values on several subsequent "measurements" was greatly reduced as well, as expected.

    Ok, it's not my business of course - just looks illogical to me. But I do agree the plastic used for MC3000 case is a garbage.

    Throw away $100 charger because of snapped pin?!? Unbelievable...

    I'd like to share my modification of MC3000: maybe it will be useful for some users. Main problem was overheating: simultaneous testing of four 18650 cells at 1A discharge rate was impossible. I've added two 30mm Sunon fans to the rear wall, one of them mounted in opposite direction - so...

    Thoraldus, I've viewed the previous page carefully: the picture you've attached explicitly shows the wires soldered to the rails. What makes you believe there's a version of MC3000 with different design?

    Wait, are you certain about that? Maybe they've updated the hardware, but in my sample (bought shortly after initial release), the wires are soldered to the rails. It was one of reasons for me to do relatively heavy modding, including addition of the wires to bypass that unstable sliding contacts...

    That's interesting! Seems like quality control failure to me. Of course you'll need to lubricate it then.

    Silicone grease is typically considered not optimal for metal-metal friction pairs, but still can be used. Are you sure factory-supplied grease is not sufficient? In my case, there's no need to add or replace it.

    Yes, I see.

    I beliveve it's thick enough to outlast the rest of charger's components. :)

    Half-second reduction of bending force, followed by several hours of spring-loaded state?

    Are you sure negative contact knows whether it was pulled by finger or by battery? :-)
