I don't normally do this, but last night I just jumped in and ordered the Wasabi BLN-1 substitute battery kit for my EM-5. The reviews of the kit (2 batteries and charger which has to be used with these batteries) are positive, and the price is much better than the OEM Oly battery. Is anyone else using these batteries in their OMD? Hopefully you are not experiencing any problem. I have my fingers crossed.
