Thank you Womblebat...... Are the CR2's 3.0 V or 3.6 volts ??????? Thank you in advance....... Imeo is coming out with a 5.0 V battery ????????
Anytime abhowe, cr2's are 3.0v (little green ones)
It's not actually a battery ab, it's a device that is the same size and shape as a cr123 battery, i believe it sits behind your 3.7v battery and increases the output of your battery to 5v
