    Bulk charging via digital DC-DC boost Minghe BST-900W

    Has anyone here had an issue where the controller unit is driving the boost converter at a 15kHz switching frequency, instead of 150kHz? The two units I ordered off "factoryfloorsweepings.com" last year were running at that in DCM boost mode, which made it incredibly annoying as my ears can...

    Shengyi X1 maximum phase current

    Heyo, The concern with the higher phase currents on the ShengYi motors is related to the possibility of stripping the nylon planetary gears inside the motor. We actually had to tone down the phase currents on our Grinfineon 25A controllers because of this specific issue on the Bafang G-Series...

    Jet bike!

    Well, If Im going to put the money into building a crazy ebike, I cant do it alone... Also I do need to go quite fast, at least highway speeds :) I really enjoy speed and acceleration.

    Jet bike!

    Can EBikes even go 90kmh with out a ridiculous amount of wattage, battery, and practically no range?(not saying the jet will have alot of range but, you get the point.)

    Jet bike!

    Edf's are crazy, but not as good as jets.

    Jet bike!

    yeah, that is the main reason why I want to do it, You will keep accelerating until the wind resistance and other factors overcome the thrust, with a electric motor you loose its thrust with speed.

    Jet bike!

    I could just use direct power from the jet, giving me about 15kw or around 20hp each instead of just direct jet. 40hp is really crazy.

    Jet bike!

    Jebus, that video above is crazy... As for the area, I have a very long road that no one ever uses. with 130 pounds it would spool up pretty fast... fast enough for a holy shit moment... 500lbs would be fun tho, because you would have trouble holding on to the handrails :P

    Jet bike!

    Jet bike!

    Hey peoples, So im planning on build a jet bike with some JetCat jet motors. Im planning on buying two p300's which produce 300 newtons of force, or around 67 pounds. It should go super fast. Anyone have any suggestions or cautions about this project? Would love to know. Cheers

    Puffy lipo

    The discharged lipo that i have, Do they gain pressure even if they are not in use?

    Puffy lipo

    Forgot to say in last post, I know not to try to charge dead lipos.

    Puffy lipo

    Little update. Accdently left the controller on with that battery :(, It now feels like a peice of warm butter.

    Puffy lipo

    Thanks, Just to be on the safe side, I think I am just going to let if be for now, The puffing is not very severe, as I said before.

    Puffy lipo

    The cell is nice and stiff, But it is a bit puffed, Its preformance is fine tho, what you would expect of a 8c 5.8 amp hour battery. Are there any major dangers of a puffed lipo?

    Puffy lipo

    Ive heared storys of people pricking lipos and them instantly turning into a blowtorch. What should I do?

    Puffy lipo

    Hey guys It seem that I am dealing with a puffy lipo, I have an 8cell Zippy lipo, which seems to have the puffs. Each side of the cell is ballooning partially, but not very significantly. What do you think I should do? The battery it self is healthy, Each cell is at 3.8 volts.

    Hello!!!

    It also sounds like it would be a pain ordering form 4 different sources.

    Hello!!!

    I wanted to order just from BMS battery, For now i think I will order the Kit with the 350 watt, And put a 48 volt on it. I was thinking of trying out the torque simulation thing too.
  23. meepmeep22

    Hello!!!

    Okay, I would like to create a bike that can go at least 20 mph, are able to ride if the battery dies on you, Able to charge other devices, has enough torque to do a decent amount of mountain biking, and can go up hills with out crapping out. I would use it 50-50 on the road and off...

    Hello!!!

    Once i get back to my place, il give you the specs. Are you saying that if i want any climbing ability, i would need to use a 500 watt?
