Re: BionX R320/R420 RIDE+ | over-voltage/temperature

The only thing I can find that is really broken is one really small resistor (SOT-323?) with the marking 1P5. It's probably a transistor. But...it's tough to find the actual part used just by the number on it, because the same code can mean several different devices. :( This *might* help, but it do...

Re: Sabvoton MXUS 3k V3 3T Top Speed issues

How fast does the wheel spin off ground? If it's exactly the same as the on-road speed, then the controller is limiting it. THat's the most likely given the description. If it is faster, by 10-20% or so, then it may be limited by the motor's top speed at the voltage you're at, or by the power availa...

How quickly does it have to accelerate to what speed? WHat kind of terrain will it be used on? (hills, etc) What kind of weather (...

Re: 1st ebike. Yescomusa battery/controller options

Definitely the battery is the heart of the system. A good one will perform better (be capable of higher discharge with lower voltage sag (so you get more power out of it) and less heat generated, etc.), last longer lifespan, and stay balanced better (so you don't have to charge as long). More expens...

Re: Chinese Tuk Tuk, need some hive wisdom

If you want to know for sure what voltage that wire hooks up to, you can open the controller and trace where the wire goes. If it's like most, that are powered off the batteryvoltage, they connect to the input of the LVPS (low voltage power supply) that generates the 12v / 5v to power the controller...

Re: Testing a 10S 36 Volt BMS

Is the BMS cutting off the pack? That means there is no voltage output at all, and if you have an LCD or other display or li...

Re: Testing a 10S 36 Volt BMS

During a ride and discharge, how does the BMS keep each cell at the same level? It doesn't. It only does it at end of charge. All it does during a ride is to shut off the output if one of the cells drops below the cell-level LVC for that BMS, which is usually right at the lowest voltage the cell sp...

Re: Testing a 10S 36 Volt BMS

how do I get the cells to be all balanced at 4.2V? Do I use a charger that balances the cells? I gave you a method to do that already, via the BMS, but you have to have a 42v charger. You can also use a 4.2v CC/CV supply to individually charge each cell to 4.2v. then the BMS will keep the cells bal...

I was thinking that with that one I would just have to isolate the 10V and the ground and that I could maybe just leave the other 3 wires cut but not insulated?

it is always good to use the gear puller hooks on the stator instead of just the side plate as it could crack. You can't use the gear puller hooks on teh stator, because the center of the gear puller has to push on teh axle which is part of the stator. You have to use them on the cover edges to pul...
