Most likely a great charger, but only 3 of the 4 charging positions worked on the first one I ordered. BG refunded the purchase price and I ordered another one (as I figured the chance of receiving a second brand new unit was next to zero) but this time I received a repaired unit with a scratched up LCD screen and, again, with only 3 of the 4 charging positions working. (4th position always showed 10 mOhm resistance. Opening up the unit showed an IC had been replaced and that one component was not soldered back in correctly after (most likely) being removed during testing. Waiting to see if BG will refund me as quickly for this one as they did for the first one and will then order another from somewhere else to hopefully finally get a good one.

The 3A is not available for NiMH which remain limited to 0.5A. It's not enough for C or D format NiMH which can reach 6000mAh. The SQ4 had a noisy fan, here there is no noise, and probably no fan, as the VC4 weights 25g less than former version. The internal resistance is measured at the beginning of charging process and is not updated. It should be because it varies during the charge. I recommend to press firmly the contacts when inserting a battery in order to obtain a realistic resistance measurement. In conclusion, I highly recommend this charger, but it can still be improved!
