No recorders I know of have have a setting to calibrate the battery meter for lithiums. You'll never know when they need to be replaced. With most recorders, the meter will show battery full until very shortly before it goes dead.
While this is probably true, I don't really see it as a big deal. The number of bars on our meters is just an indication of the battery voltage. New lithiums spec out at the same voltage as new rechargeables, so I'd think you could get a good general indication of the amount of juice left if you just choose a battery type that has a comparable starting voltage as your lithium.
As far as the manner in which the bars disappear, that also is just a function of the fact that voltage drops fast as the battery depletes itself...which is no different between a rechargeable and a lithium if you check the battery discharge curves in the spec sheets.
i run nothing but lithiums
i get 60+ hrs of recording time
for instance i put new ones in on march 8th 2012. have recorded at least 40 hrs since then.
and i just finished up 20hrs of recording at a festie this past weekend and still have full bars.
i always have 2 fresh lithiums on hand and can swap them out in less than a minute.
i won't run anything else in my m-10
Damn, 60+ hours
Thats INSANE buddy
But youve only recorded 40hrs since that moe. show? Slacker
J/K Kev
I have recorded around 200+ hours this summer at 3 Phish shows and Summer Camp/Electric Forest/All Good/Rootwire
Recording all that shit has KILLED me tho. I wont be done uploading those HOURS of recordings til next May probably
Just in time for Summer Camp
Thats why I sold my Busman BSC2 rig. Recording 2 stages at big festies just isnt for me
Its just TOO damn much work
