Ever wondered what is inside a Victron Smart Lithium Battery? Here is an inside photo to show a bit about what is going on. This particular battery had an unfortunate accident involving a dock cart and a dog. The terminals got damaged and have been removed. Fortunately nobody was injured.
This is a 160 Amp Hour battery and you can see that there are eight cells total in a series parallel arrangement to give a nominal 12.8 volts. The electronics you can see comprises the cell balancing circuits, the bluetooth circuits and the BMS interface.
We recommend that you don't try this at home.
