Is this for the E-5 or the E-M5? (I ask because the BLN-1 is the E-M5, but the E-5 is in the subject).
If you're looking for the BLN-1 for the E-M5, I've had good success with the Wasabi Power generics. They've worked very well for me, and I picked up two along with the charger for about $30.
Agree on the Wasabis. I picked them up for, I think, $23 or so on Amazon. You get a direct wall plug charger (very useful given the odd choice of Olympus to give a corded-only charger) and two batteries. I find that the 2 Wasabi batteries don't last as long as the OEM battery, but since you get two back-ups, it is still a pretty good option.
