Re: weird motor noise after changing hall sensors.

Im not sure what you mean "at the controller PCB itself." I've tested the halls at the black/red leads vs the other colors for the halls hand spun and the readings range from 0 to 4.** just fine :S

Re: Making a bulk charger.

Your charger sounds very interesting so how much is it going to cost you to build it all, do you have any pics? Build cost is about 20-30 dollars in fets (could be done for 10 dollars - but with significant heat production and ~10% efficiency loss), 5 dollar mcu,, 4 dollar current IC sensor, 5 doll...

Re: Making a bulk charger.

I'm working on such a charger atm. The only problem is it will be rather unefficient at 110vAC, mine is designed and works at 220-240vAC. It's a simple, yet very efficient charger. It uses a AVR to sense ZVS (AC directly into mcu is cool :twisted: ), and use either of the two mosfets to chop the AC...

Re: Making a bulk charger.

Alright so I want to confirm these settings to make sure I put the right values before ordering. So I have a 30S2P each pack is 6cells at 22.2 Volts. With a full charge at 25.2 Volts. (ZIPPY Flightmax 5000mAh 6S1P 25C http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=8586 ) Battery ...

Re: weird motor noise after changing hall sensors.

Im pretty sure I did that already and got a range of 10k ohms to 20k ohms depending on how long I keep the leads on there. Does high side mean the right wires and low side mean the black wire?

Re: Making a bulk charger.

Im a fast learner. I have a decent amount of skill with electronics. I was looking for something that was more potable to the meanwells in series isn't an option I guess. I prefer to have one unit.

Re: weird motor noise after changing hall sensors.

xD is there a guide anywhere on how to use the tester, Im still a noob at this lol. I checked the resistance from black and red to the phase wires all are okay its resistance starts at about 10k and goes up to like 20k. So not sure what the problem is, I tested my hall sensors before I put the motor...

Re: weird motor noise after changing hall sensors.

Hey, so would you suggest that it has something to do with the controller? I wonder if a new controller would help.

Recommend me a bike

Im looking for a fast e-bike. I've read many post on here but still a little confused. My budget would start off with about $500 not including the battery. 1) Do you care whether the bike is technically legal or not (in terms of power)? No, but would like to know what the limits are in Winnipeg. 2) ...
