Hi, Robbert! Nice to see you here! Actually, we are in need of new pleo batteries already, at least for the Ugobes which are the older model pleos. Any other alternitive to searching out batteries on EBay would be awesome.
I own both Pleos and Aibos and I think your project is awesome. I am especially impressed with your ERS 110 and 111 batteries as they are in such short supply right now. Unfortunately I can't help financially because I'm saving to move at the moment.
