Baking Li-Ion batteries or Fahrenheit vs CentigradeAnother thread was talking about lithium ion batteries and overheating. This example wasn't meant to perform a test on the batteries but is what happens when you misread centigrade for Fahrenheit on your temperature chamber. You get two very distorted batteries and singed fingers. One of the engineers Monday, misread the readout while testing two devices at 140 degrees. He didn't realize the error until he picked up the devices and scorched some finger tips. 140 C of course is 284 F. To widespread surprise, the units still worked and so did the batteries, though now they don't fit in the battery compartment very well. We also now know that the LCD gets very fuzzy at 284 F. Now you know what we mean by half baked designs. Best Regards, Larry Fisher Lectrosonics
Np 1 lithium testingHi I´ve been testing Np 1 Lithium Li-ion Ultimate NPLU-84. 14.8 V 84 Wh from Pink Noise. New battery and fully charge with my old IDX KL-4 charger. The test was Sound Devices 664 with 2 mic. phantom power ( Schoeps MK 41 and Sennheiser MKH 70). And power for two Audio Limit 2040. At 8.15 AM I arm four tracks and hit the recorder button . I was recording constantly and stop for lunch12.30 PM where I power down the lot. At 13.10 PM I power up everything and was recording again constantly. At 17:00 PM I have my first warning for low power. I keep on recording and at 18.20 the SD 664 stop. Warning low power not able to record. The SD 664 keep the files intact. Very nice. Note I was recording indoor, 20 Celsius ( 68 F ) I was recording 9 hours and 25 min with one NP1 , two phantom power mic ( 48 V ) and power for two Audio Limit 2040 receiver. I do find this very good, and looking forward to try them outside in the cold winter time here in Denmark. ms
