Guys, you are both right and wrong. We have these facts: Aluminium (pure) Resistivity: 0.028 ohms*mm2/m Density: 2.7 kg/dm3 Copper Resistivity: 0.0172 ohms*mm2/m Density: 8.96 kg/dm3 So, if we compare two wires of equal cross-section (mm2), copper beats aluminium. But, with the same weight...

I think another reason for the clutch is that they are using a sensorless controller.

Well, yes, it would work and basically this is in a way how simple BMSes are designed but if you read my post again you realize I was trying to argue against balancing during end-of-charge. Or balancing voltage only at a certain state, without taking into account the capacity of each cell...

OK, I am slowly beginning to realise the extent of the confusion. I think you are trying to solve a problem that doesn't need a solution. So the simple answer is: don't. In a series connected string of batteries, cells participation in the current flow can not be limited. Some...

I'm also not sure what safe is trying to establish, but I can confirm a few of his assumptions and ideas. 1. The internal discharge rate of litium cells is very low, which means that balancing can be done either very slowly, seldomly, or even manually/occasionally. If a pack is balanced (or...
