The SoundDevices MixPre6 is a great audio recorder, but it’s fairly power hungry and on the journey to find the best power solution for me I bought a TalentCell battery from Amazon here: TalentCell battery (yep, that’s an affiliate link).
The battery was less than $40, and with the addition of a Cable Techniques Hirose connector from B & H, it was ready to use after some charging.
First unpleasant discovery was yesterday, when the recorder just shut off. This was disturbing because when using the regular AA battery sled I get plenty of beepy warnings that I’m about to run out of power.
The abrupt end makes sense though, considering that the recorder was still getting more voltage than it would from AA’s when the battery itself decided to shut off.
So hence the test today to see how much recording time I can get before it dies.
Over 2 hours so far, but I expect at least double or triple that.
UPDATE: I got a total of 495min and 7sec before the battery shut things down. The ending was abrupt as it was last time, and a bit disturbing because there were clearly two lights out of five on when the battery died, same as last time. So, when I use this battery I’ll need to keep an eye on the record time, or just treat two lights as a signal to charge.
