Re: Field trip to powervelocity a.k.a. Vad's house.

Update: Running the controller at 4kw peak on a 18s pack and it's very quick. much faster response from this than my adappto which is weird. when adappto is set to 6kw peak, and this one set to 4kw, PowerVelocity's controller is more powerful. Which would seem to indicate it's more efficient. also m...

Field trip to powervelocity a.k.a. Vad's house.

Hi all, I like vector and really enjoy my vector/adaptto bike, but I was intrigued by powervelocity's inexpensive Bluetooth enabled sine wave controllers. And as luck would have it he lives near my dad in Sacramento California so I stopped by to say hello, and take his controller (and entire bike)fo...

Re: Vector e-bike Frame 599$ /Adaptto/Parts WORLDWIDE

Hey Arthur,
I noticed people seem to be either sold out or have very limited quantity. why is that? is adappto not making a bunch or are they being sold inside Russia?

just curious.

Re: Need help to choose my new controller

For any motor more VoLTs 2"will give a higher top speed assuming unlimited amps. More amps will give faster acceleration, same top speed for the same voltage. I don't know that scooter, but the first thing i did is ditch sla for lithium. Lighter is faster Also less voltage sag is faster. When you pu...

Re: Salvage "older" 18650 cells from laptops.

No, don't get them.
Used mixed cells will go out of balance quick and be a pita to charge. Also laptop cells are not high c rated so you'd have a big low output pack. I got 40 laptop and tried it. Huge amount of work for little reward, not worth. It even for free imo.

recomendation for a 75v-->12v buck converter?

hi all,
I stepped up my voltage from 48v to 66-75v and need a good buck(step down) converter to get the voltage down to useable levels-12ish volts.

All the pre-made modules I can find top out at 60v, anyone know a good one that can handle higher input voltages?

seconded on checking cell balance. is the pack sealed up or can you read the per cell voltage? if you can check per cell, ensure that they are all the same. mine are 4.21 4.20 4.19 4.20, etc, when i'm done charging, and 3.44 3.45 3.43 3.44 etc when I'm done. This is a pretty good sign that your not ...

Re: Adaptto Mini-E/Max-E Owner's Thread

Artur is helping me via PM. looks like red/green are power, but I accidentally hit the chassis. as you said, keep them isolated, as it's just a loop to provide power to the brains of the unit. I'll follow up once I get things more figured out.

EBK got so tired of fat guys wanting warranty replacement of that motor when running it at 48v, that we put a 200 pound weight limit on it, and only warranted it for 800w (36v). I'm not saying you are fat, just that the motor can get overloaded by a 200+ pound dude riding hard on steep hills. Now w...

too much trouble, my neighbor has a oil cooled motor, but I really just want to get home on the lightest possibly bike, I'd rather add a thermo-control unit to kill power when it over heats. I dont' NEED to be going that fast. I just have self control issues.

Sounds like a nice little gearmotor. I was recommended to keep my BMC under 1500W for long life, is this motor a bit smaller even? I've ran my bmc v2t at 2500 for about 3000 miles now, I did cook a HAL at 60 amps, 100v when I was playing with it. These days I'd prefer not to get killed. 50amps 48v ...

Have you all been doing this by hand? or do you have CAD files for it? I'm thinking of trying out E-machineshop, and this looks like a great project to start with. if anyone has cad files they'd be willing to share that would be awesome.

Re: My price / benefit comparisons of lipo vs lifepo4

Started lead acid. Garbage. Then 48v 10ah lifepo pack. It was lighter and faster, but still big and wanted more speed. Upped amps on controller and lifepo sagged horribly at 40a. Then, after 50-100 cycles, wear and tear on battery started. Bms buggy, so pulled it, charger broke, replaced, a cell die...
