Battery Banks in fablab

Does anyone have any information on the battery cells in the fab lab. I’m in talks with some friends to start a project that would require some large batteries.

Does anyone know who the current or previous owner is. And/Or the nature of these batteries. I have been trying to look up the specs of the packs themselves, but I can’t find anything from the limited information printed on them.

Are those the ones from Power series racing? Can you post a picture of them? Because I’m not sure what you are talking about.
