I seem to have overcharged the NiMH battery on the Erlerover to ~8.7V. I have read that the PowerModule has got a maximum input voltage of 18V and outputs 5.2V to the ErleBrain 3.
1. Is it dangerous to connect the NiMH battery to the Power Module on the Erlerover at 8.7V?
2. My Lipos (3S) do have a higher voltage at around 12V (~4V each cell), can I nevertheless connect them to the Power Module?
