Hi all...
just thought id post this.
Edirol tells me that with 1850mAh AA cells, the R4 will record for 4 hours continuously. i'm sure that is at 16/44 though. I just bought a shitload of 2300mAh AA cells from batteryspace.com ($29 for 24 cells!). And will do all sorts of recording tests with these at various resolutions.
Wouldnt it be the shit to get a solid 2.5 hours from the internal AAs at 24bit ? I think so.
I would probably never carry an external pack.
but...just in case, there are KILLER deals on eBay right now for 9.6v RC packs. I am about to buy 3 2000mAh RC packs for $25 or something rediculous like that. Add custom cable, and there is a 6amp pack for under $30. pretty sweet.
