Hi everyone Thought I'd ask here first since I don't necessarily want us to be the first to try something like this... Last year we bought a full set of BA2015's for our EW100 G3 sets. I didn't mind paying a little extra as I thought the charging control mechanisms built-in to the BA2015 packs would maintain a longer useful life. Predictably, less than a year on from purchase and deployment I've just got word of the first "live" failure of one of these packs. Showed green light when the mic was in the charger, full 3-bars when turned on, and died about 30mins into the gig. On the one hand, I could send the dud back for warranty replacement, but it got me thinking... has anyone had success with: 1) Using the L2015 base-station chargers to charge standard NIMH AA's in the mics 2) Swapping out the cells in the BA2015 packs with standard NIMH cells? Boss is suggesting calling Sennheiser. Having no desire to sit through yet another semi-automated call-handling system, I'm guessing that the first word of the response will begin with "N" and end with "O". And it won't be "Nando". :) So - anyone done any hacking on these?
