    the motor M820 have two vesions, 36V/ 43V, so the main battery also have two vesion: BT F100 36V 360wh and BT F014 410wh, and extended battery we find one is 36V 360wh, can not find any one with 43V, Display you can choose DP E180/181, DP C262/263, and DP C244/245 is also ok,

    yes, M820 have 36V, but the main battery is BT F014 410wh, it's 43V, that's the problem, To keep the main battery and the motor consistent, it is best to use 43V,

    This is the size of the box of range-extending battery, the battery manufacturer give me that. It can only be installed with a 10*2 cell arrangement, 36V*10AH. What we want to try is a 12*2 arrangement, that is, 43V*10AH. and some problem is till no solved

    you are right, The biggest problem now is that the main battery is Bafang BT F014, 43V, so the motor also uses M820 43v, and the range-extending battery is 36V, the battery manufacturer is still thinking about it,
