    Where to find the right hub motor for me

    Ok so, I have an approximately 45mm wide cassette and a 135mm dropout. 5mm too much ? No motor are slim enough to accept a 45mm cassette ? What is the difference between rear and front motor ? Also I just need "pedal assist" that's why I target low power motor. Like this one ...

    Where to find the right hub motor for me

    It's just because it's what I have so there is nothing to buy other than the motor. Also I'm sure it is compatible with my shifter. I'll measure the space it takes.

    48V Charger

    Yeah cycle satiator would be the best but a bit overpriced for me. Is there an open source diy design of charger based on mosfet and microcontroller ? Anyway I think I'll order from em3ev it seems to be the best price/functionnality charger. Thanks everyone.

    48V Charger

    Hey and thanks for the reply I have mesured the output voltage without charge its 57,6V, I don't think there is a pot somewhere I think it's based on voltage divider and opamp with fixed value resistor. My BMS Should cut power when 4,2V per cell and it needs trickle charge to balance the cell...

    48V Charger

    Hi ! I'm converting my scooter to lithium (1 of my 4 Acid Battery died) and I need a new charger. I already have a 48V lead acid charger, it says on the back : "output 59VDC 1.7A" Can I mod it to output 58,8V to charge my 14S5P Samsung ICR18650-26f battery ? I have a BMS with 16A charge max...

    Emmo Urban lithium upgrade

    The cells are Samsung ICR18650-26F not the best but its what I have now, so 3,7V * 16 = 59.2V and 67.2V Fully charged but the problem is that : I don't think this DC-DC will be ok with 60V but with 51,4 (14S) should be good, what do you think? This is the inside of the controller how can I...

    Emmo Urban lithium upgrade

    Yes I understand but my acid has maybe 12Ah left and is only 48V so 576Wh of energy and a 16S lifepo4 with 10ah has 512Wh so, in theory with regenerative braking, I have more than 30km and I need 25. Its good but what I want more is performance and I dont know how many amps my acid can put but...

    Emmo Urban lithium upgrade

    Hello, I own a 1 year old e-scooter "Dyad E500 or Emmo Urban ..." with 48V 14Ah lead acid battery. I mainly use it with two passengers, and when I climb hill it's very difficult for the scooter I think the limiting thing is the battery so I want to change it but I don't know what is the best...
