I have an Elan 7N and the 33V equivalent. They take CR123 batteries. Does anyone know if I could use the rechargeable RCR123 batteries? The CR123 show 3 volts and the RCR123, being li-po, show 3.7 volts. If it were just one battery and a difference of 0.7 volts I wouldn't worry, but it takes 2 for a difference of 1.4 volts. They are both really sweet little shooters and I would hate to let the smoke out of them.
