    I have SparkFun 6000 mAh 1S 3.7V LiPo battery. It is made of 3 pc of 2000 mAh batteries.

    Should i balance it?

    I think with LIPO batteries in general, a balance charger such as the IMAX B6 must be used.

    It would appear they are in parallel so I don't think balancing is required.

    Do you have a balancing charger which is capable of doing 3 cells?
    If so then just always plug in the balancing plug when charging .

    If you don't then use your voltmeter to check the individual cells on the balancing plug of the battery.
    It's recommended that the cells be no further than 10mV apart . The less the better .
    Concerning cells in parallel : Slight voltage difference between cells probably won't be an issue if you are trying to pull small amounts of current but if you try to pull currents close to max rated currents then you might be overloading some cells more than others because lipos have a low ESR which means that the cells with higher voltages would have to already be discharging alot of current before their voltage drops to the voltage of the lower voltage cells .
    What this basically means is that you will be overloading the higher voltage cell/cells and overloading cells in lipos doesn't usually end well.

    Please correct me if i'm wrong.

    In general it's just better to keep lipo cell voltages as close as possible

    I think you only need to worry when the cells are in series (multiple of 3.7 volts) where one can be 4.4 volts and another 4.0 volts when the charger turns off. So one is over charged and the other not completely charged. Since his cells are in parallel both (or all 3) will always be the same voltage.

    My quote in first post is from:

    I don't have any balancer right now.
