Quick question about chargers. I have the 30D with a few batteries and will be traveling next week. My buddy has an old Digital Rebel. Now as I recall sense I'm the one that sold it to him I thought it had a different BP511. One was NiCad and the other was something else. I'm just wondering if there will be a problem with me borrowing his charger and charging the BP511's from my 30D with it.
