Great for Flashes!

At last I've found the right source of energy for my photo-flashes: They can be forever carry around in the camera bag and when you need them then, they allow pleasantly short recycling times in my (not representativen) Direct.

Recycling times Metz MZ40-3i at maximum flash power and fully charged batteries:
3.8 sec: Sanyo Eneloop 2000mAh (R = 0.18 Ohm)
3.8 sec: SONY 2500mAh (R = 0.18 Ohm, rapid capacity loss during storage)
4.0s: PANASONIC Infinium 2000mAh (R = 0.18 Ohm, now have a 2100mAh)
4.5s: SONY 2000mAh Cycle Energy (R = 0.19 Ohm)
5,6s: GP 2700mAh (R = 0.23 Ohm, rapid capacity loss during storage)
