OK, so is anyone having issues with batteries that are not freshly recharged? The third time I've used batteries that have been charged to ~2700mAh each about two to four weeks before using and the 660 lost power before the 3.5 hour mark.
I'm sure it is not the 660 but the power supply.
I have had this problem as well, but well before 3.5 hour mark. The shitty part too was that when it died, I lost the recording. This is the only time I had lost power, and it could have been a one time event in terms of losing the recording. But I always re-charge the night before the show now.
a fresh set of lithium e2s will run a 660 for a freakin' long time. longer than you'll need outside of a festival.
Agreed....I started out running these before I got my rechargables, and I remember adding up the sets and I think it came out to around 8-10 hours but I am not sure. Since having the power issue above, I like to rely on the e2's for shows that I can't live without.
