Re: Replace dead controller for a 8fun hub motor

I have already a kt-lcd5 72v, do you know if it's compatible with 36v battery? (I dont found this INFO in the manual) A 72V controller will cut off at 60 volts, give or take. Most KT displays allows you to change this value by a volt or two either way, but not more than that. I speak about the disp...

Re: Hub Motor vibrates but does not turn; works with different controller

almost all of the issues i seen with lishui controller tends to be the controller not working. hardly ever do i see anything where the hub motor is burnt, even when pushed hard. seems like the motor can stay cool but the controller overheats when pushed hard and gets slightly bricked. i would say, h...

Re: $195 48v 19.2ah lg18650mh1 cells

picked up batteries yesterday and tested out to be better than expected. sag on ebike stock was about 5-6v on full throttle stock and now it's only at most 2V. so completely happy with battery and better range. pictures for your enjoyment.

Re: Replace dead controller for a 8fun hub motor

Thank you for the first feedback. I search for controller but I don't know if all controller is compatible with all display. I'm not sure how to choose. For reminder, it's ok to replace controller and display together. Concerning the old controller, I removed them from the bike and check the cable ...

Re: Puzzling battery issues with a Luna Wolf battery pack

What would be the objective of such a test, how would the result be useful? ? What chemistry? What temperature? Link to the datasheet, look at the min temp rating. If not **used** while "frozen" like that, should have little impact. But with a lithium pack, **charging** it that cold may r...

All,
I got my package today. It took a while but he delivered what was described in his ad.
BMS in this battery has a common port type. You don't need a separate charge port. The discharge port can be used for charging. This will simplify the layout.
can you show pictures of this please?

So I currently have a Bafang 48v/500w rear hub motor and the controller for it is 20a max. I am considering upgrading to a KT controller (25A) to get a little more power out of the motor. It seems no one really makes a controller over about 20-22 amps that is a direct swap for the type of controlle...

within 0.1V per S-count is a decent rule of thumb

So for 13S, 1.3V max difference when paralleling
