dont be scared of the "only" 2450 mAh capacity
they do was well as any "2600" or "2700" , and more importantly they are built to keep capacity a long time
i am not exaggerating when i say i would expect them, with a good charger, to easily last 5+ years in 'critical use' before being relegated to remotes, toys,flashlights etc.
i dug some old abandoned eneloops out a drawer. had to be 10-15 years old. tested at 90% of rated capacity when tested on the powerex
the #1 advantage of the maha wizard charger is testing capacity. i write the number right on the side with a sharpie, and then i have 'matched sets' of batteries. i dont mind having 550 maH AAAs, i just use them all together in my headlamp, and keep the 800-900s together as well. And of course the usefulness of matching cells for a taping application is obvious. Weeding out a single weak cell could be that extra hour you need to make the show happen
i get that you might want an 8-bank charger for your mixpre, i had one as well when i had a mixpre as i used the 8-cell sled. personally id rather have the super dope 4-bank charger and keep an extra full set of 4 cells. so if youre doing shows night after night you can get by with only charging 4 overnight and have 8 ready to go, if that makes sense
