Could you please suggest wich controllers to buy for 48v 500watt dual hub ebike?

Hi, do you know about some bldc controller that can select forward / reverse direction with a switch? Thanks!

I have a scooter with dual motor, there is a button that controls whether I choose to use one motor or dual motor. The scooter was taken to a repair man to change lights but ever since the button no longer switches between one motor or dual it is stuck on dual. How do i set up the wires on the button so that i'm able to select to run on one motor or two?

This only works if you have a single battery pack powering both controllers and hub motors.

But what if you had a separate battery pack for each hub motor? simply sharing the signal wire to both controllers wont work. So I wonder, since it is a bad idea to run two separate LiFePO4 battery packs in parallel considering both packs have their own BMS ... could you share just the ground wire between the two batteries?

Since each battery's positive is ran to its own controller & hub motor, the shared ground path should serve as the connection between the two controllers on the shared signal wire... Right?

If I am right, I have no idea if I am... Is there going to be any issues with current feedback or oscillations? And, will the shared ground path interfere with the BMS on each battery?

Can you tell me how to connect the remote control to the motor drive

[larrymacdonald]

Personally, I just split all 3 wires to each controller, one +, one -, one signal wire, usually red, black and it's only a 5v @ 0.1 amps so it's not like your going to fry the throttle by connecting two sets of 5v leads, I've been doing it for years....8 or 9 years, besides, if one motor fails, you dont have to rewire to get the other motor to work on the side of the road !!! you can just continue with only one motor until you get home, been there... done that...dead hall sensor

Thanks! Building etrike with 3 hub motors.

Do the 2 controllers and motors need to be identical?

[squidlings]

So it's only the difference from the pot which the second controller needs. Awesome! Thx!

[von]

how about the display? how you connect 1 display ung 2 controllers, and does the speed gears work or not?

i want to know if i can connect two batterys 48 v. thru a spliter then put a y connector to both 48 v. controlers. then i can get more amp hours from my batterys. i use 2 different throttles.

Other question: If two lcd are display controlert want a lcd/to a gas throttle to set, it how is needed?

[ryyanbennet]

How many times can the signal be split amongst escs?

[rlmqlvf]

do you need the hall wires to do this or would it work with out it as well

[andreiyutube]

The hub motors must be the same power or can they be different ? For example a hub motor 48V 800W on rear wheel and a 48V 500W on the front wheel ?

hey hello I could solve a doubt, how could I use the engine brake on both engines and with a single brake lever I place them parallel or how I should make the brake connection thanks and greetings from Spain

[oplkfdhgk]

Can you do this with brake lever too? 1 brake lever but 2 controllers.

[messor]

Another question: how do I connect two controllers to an LCD display throttle lever?

[shamellsanchez]

regards! Is it possible to know what type of controllers I need for 2 hoverboard motors, a battery and an accelerator? I would like to know why I am undecided which controllers to buy for this project?

[madmaxx]

please help. im running two batteries, two motors, two controllers how to put switch between both controllers? thx
