Dear Group, My company is working with the orignal designers of the batteries here in Australia. If you need to more detail information about the batteries I can email more technical informaton about them as I do'nt want to flood the group with to many Files. I don't know about Canada but here in Australia the smallest unit that they are producing is a 10kw/h system that will retail for about $25,000 australian. The maxium power that can be drawn is 5kw for 2 hours or any part of that. The system has a round trip efficency of about 80% and can be charged and discharged at a rate of 5kw/h.
