    hi!

    I have two power supplies 13.2v 4A to charge some Lipo Batteries from some light spots.

    I started to charge two batteries, each with one power supply, and they got unussually hot for my taste. Is it somehow possible that because I have them really close to each other, on top of each other fastened with tape, there is a kind of coil effect or something like this that could have provoked they getting hotter than ussual?

    you cannot just connect any ol psu across some lipo batteries !!

    The psu needs to be specifically designed to charge LiPO's

    At worst the batteries will explode, and set the surroundings on fire

    Do some googling on LiPO charger circuits

    Just which is it you are concerned about, battery or power supply.?
    Show the battery and power supply units and any links to specs you may have.

    which you didn't state in your OP

    so, make and model of the PSU's any links you have to where there may be info for them would also be really helpful
