    Hi,

    I'm wondering if it is harmfull/ or in any other way not advisable to discharge rechargable batteries at a high rate. I'm thinking about using 6 of them in series to power a 5 ohm coil (PWM). So expecting to draw about 1.5A

    Thanks,

    It all depends upon the type of battery(chemistry) and the AH(ampere hour)rating of the battery.

    The batteries I have are Ni-MH; 1,2 Volt 900 mAh (AAA)
    It is also mentioned on the battery that the charging time is 15h at 90 mA

    According to the Energiser NiMH Application Manual (search for Energiser datasheets) the maximum discharge rate is 4C so you should be fine.
