    Battery dilemma - Voltage

    Hi, i have a dual motor DD hub bike that runs on 72v but at top speed it's amp consumption drops to mid 30's. Now, i intend to build a battery, but it occured to me that i could increase it's voltage, by option is between: 20S8P - 160 Cells - 72v - 16.8Ah - 240A Max Continuous Discharge or...

    BMS connection doubt

    I did, no answer yet, thought that one of the gurus here could have encountered this already.

    BMS connection doubt

    Hi, i have a doubt connecting this bms, my issue is the 2 red wires next to each other. I assume i should start with the black wire to the "common" negative and then connect each wire to each parallel, but those 2 red ones are confusing me. If they just go all to a parallel connection they...

    Chinese pack + new cells

    I see, there's just no way to increase C rate besides a totally new battery. Gonna put 30 of those sanyo's and 130 25R's. Thanks.

    Chinese pack + new cells

    What do i have to make sure, when connecting two packs, each with it's own bms? Im thinking about charging too, do i charge them isolated or in parallel too? Also, i assume the discharge current adds up as it does with any parallel setup, right?

    Chinese pack + new cells

    So...packs in parallel are ok, even if with different capacities? Wouldn't one charge the other in reverse? About the regen, what is the issue with it?

    Chinese pack + new cells

    Ok, thanks, one last question if i may, can i mix: https://www.imrbatteries.com/sanyo-ur18650nsx-2600mah-20a-flat-top-battery/ with https://www.imrbatteries.com/samsung-25r-18650-rechargeable-battery/ The issue was i ordered 30 sanyo, and now they're discontinued, the seller went out of stock...

    Chinese pack + new cells

    I see, they will try to equalize the voltages when connected in parallel. But would it work safely, despite the discharge rate difference? And im struggling with trying to understand the @MadRhino's remark about the weakest link in a chain. From my understanding of it, since i would connect...

    Chinese pack + new cells

    Hi, i've been reading about mixing cells in a pack and i understand that the series string cannot vary in voltage, for example. But im confused about this particular problem. My idea was to add 1 or 2 parallels to my current pack, which is a 20S7P with chinese generic 2.6Ah cells. These cells...

    Controller plugs doubt

    It's with great pleasure that i inform i managed to install and test the brake regen, all left to test is with full battery, from what i read, it's not supposed to work over a certain voltage in the battery.

    Controller plugs doubt

    Interestingly, or not, found another picture in the seller item page, and this time i noticed the "regen braking" plug. I'll try attaching and see if it does work.

    Controller plugs doubt

    Hey there, im back, got an issue regarding Low brake, i was under the impression that using it would not only cut off the throttle, but also apply a moderate braking. It does cut off the throttle, but i feel nothing slowing me down, apart from the lack of throttle. This L-Brake has only 2 wires...

    Many thanks for the answers. Best regards.

    Controller plugs doubt

    Sure, but would the higher value give more top speed or is it only a question of more amps?

    Controller plugs doubt

    "If you want to just leave it on speed 3 all the time, you can just connect two of the wires." If i understood correctly, one of the wires is a ground, the other two is either the 50% or the 110% or whatever. I do find it weird how it can give more than 100%, since there's no more volts to put...

    Controller plugs doubt

    Hi, i have a controller that i got working, but im curious about the plugs "3-speed" and PAS. What do they do, and how do i connect them? Also a doubt as to how i should connect the brake plugs, the Low brake is supposedly the regen and the H brake the e-ABS, is this assumption correct?
