Negative Positive
Title: Flawed and hazardous
Review: I tested these batteries after buying two of them and the Thermistor that should be giving the charger the battery temperature for safety has been replaced with a ~10k resistor.(Check your packs yourself, touch a multimeter set to measure ohms to the - and the T terminals, it should be 15k if the battery is freezing and down to 5k if the battery is hot)I consider this hazardous. I do not recommend these to anyone.(The grip however is probably fine, this review is simply about the batteries)
Is the review positive or negative?
