Using these on Shure body packs at a local live theatre. Also using the AA batteries and chargers on Shure body packs
Total of 26 systems live at one time. These are great. Have tried other rechargeables without success. These really work. We easily ran through 1000.00 worth of disposable alkaline in rehearsals and a 11 day show run . Other bad thing about the disposable batteries is they would always last through 1 show but never through 2 shows so we had to throw them out after every performance even though they would still last for another 2 hours. These recharables eliminate our waste.
