Parallel Batteries - Why is that a short

I don’t understand why it says that the voltage source is shorted. In reality, I should be able to connect batteries like that, or would I need something like a diode in front of each battery?

The ideal voltage source has zero resistance. In the real world all batteries will have some resistance, but in the simulation just add a few ohms (or miliohms) in series with each voltage source.

@guillian, thanks for answering this. I tested by adding two resistors on each battery and it works.

This seems to be a common question. (https://everycircuit.com/circuit/5398362129694720 https://everycircuit.com/circuit/5264000260767744 https://everycircuit.com/circuit/4851389028368384 I would please add that it's not recommended to attach batteries in parallel in practice, too. If you do, make sure to add series diodes so current cannot flow backward through a battery and cause problems. Good luck.
