I'm onto it - thanks for the heads up. If this is as good as you say this removes any justification to update to the Line 6 versions.
I have heard great things about enerloop rechargables but unfortunately they don't do 9v batteries.
I gig pretty much every weekend, and one full charge will almost do two 4 hour gigs, so I started charging them after every gig... I also thought about getting the G90, as one of my guitarists and several friends in my area are using the G50s with excellent results, but with the Li-Ion 9v rechargeables, I don't see the need...
I currently have 2 batteries, a charger, a total of 3 transmitters, an XDR-95 receiver, an XDS-PLUS receiver, and several spare trans cables - all of which are working quite well... So, I've decided to keep using that stuff until there's a compelling reason not to - after all, I'm currently running great sounding wireless at zero operating expense - what's not to love about that...
I've been using the Hi-Tech 9v rechargeables for well over 6 months now, and only recently "used up" the 1st battery - so, besides being "green", they've saved me a fair amount of money and trips to the store... I was paying around $2.50 each for Duracells, one of which would cover a 10-2 gig for me... One Hi-Tech 9v and charger cost me around $30 shipped, so I figured that after 15-16 shows, I'd be at the "break even" point for Duracells vs Hi-Tech... I ended up getting around 50 shows out of the 1st battery, with zero issues - so they were definitely worth it to me... Since I actually bought 3 batteries and a charger, the overall savings will be even better than that: I'm figuring 1.5-2 years of gigging around 75x per year, and have $56 total invested... I'm actually thinking about buying another battery or two, and a 2nd charger - because my X2/Line6 stuff will probably go atleast another couple of years, given my experiences thus far...
I looked into the Hi-Tech batteries for over 6 moths before jumping in - and it's proven to be a good decision...
