How much battery life are you guys getting with NiMH? I cheaped out and am paying the price with crappy battery life.

I got slightly over 30 hours with my Maximal 8.4 volt Li-ion batteries.

^^^Wow thats really really good. I haven't actually measured but I think Im getting less than 4 hours on low gain.

You may have a bad battery.  Which brand are you currently using right now?

Ouch... I'm getting roughly 20 hours with the 9.6V
 
I'll report back after I test a fresh charged pair. 

 
Anything above 20 hours are plenty enough IMO.

Does Justin have the black in stock? I thought he only had the grey...
 
If so, I may order another one for a friend. The wait will be quite awhile, since a fresh batch just released last week, so be prepared for that.

Okay so the battery actually lasts a lot longer than I thought, measured yesterday at around 13 hours. I think I wasn't charging the batteries correctly or something.
I also have a question, the red LED turned off yesterday but the amp still had battery life (about 1.5 hours after the light went out the batteries died). Is that supposed to be the low battery warning? It turned back on with fresh batteries.

the LED will turn off when the batteries dip below 12v or about 6v per cell
 
and 13 hour battery life would indicate a battery capacity of about 190mah, which is probably average for cheap NiMH batteries but there are ones available with much higher capacity
