Re: Power issue and crackling noise

That's a very good point and very helpful, I will try wiggling the wires to see if anything noticeable happens with the connection. I'm using a Hailong 3 battery pack. I think that would be the shark style you mentioned? Its very starange how it crackles though, however that only occurrs when the sp...

Re: Power issue and crackling noise

Thanks for the advice. Maybe next time reduce the levels of sarcasm. Not all people find that acceptable. Helping minus the sarcasm would be great and be a much more positive step towards people's communication with you. I have found better help on this subject from other forums with more profession...

Re: Power issue and crackling noise

Ok I've been over all wires and connections extremely thoroughly and I cannot find any loose connections. I have however noticed that when I switch the battery on at its switch there is no crackling, the cracking only starts at the point I switch on the esc? Any thoughts?

Hi all, I am new to the ebike world, I bought an ebike at Christmas and all has been going fine until yesterday! In a nutshell... I was riding along and all of a sudden I lost power for around 10 seconds and the display was showing the voltage going up and down, literally from full to empty, full to...

Re: Electric scooter Overheating Issue

If the outside of the motor is that hot, the insides will be a lot hotter. Too hot and the winding insulation will fail or the magnets can get demagnetized. 60C is about as high as you want it to go. Motor heating is mostly a function of motor current and air flow. Either you reduce the current (no...

Re: Motorino XPs

It's odd how it's only happening on your return journey though. It doesn't make any sense.
I think you can pick the controllers up pretty cheap. I'd personally replace it. Has the bike done alot of milage or quite old?

Re: Motorino XPs

I've recently replaced the batteries and bought a new charger. Replaced a couple of bad positive/negative battery wires, looked over the wires and their connections, and checked the two fuses. All looks good. While riding to work (7 km.), everything runs well. When it's time to come home...it's a d...

Re: Will upgrade Razor E300 to 24V 500W brushed motor be effective?

Ok, Make sure you change the speed controller also, it will need to be a variable speed controller. Just in case you wasn't aware. Yes you'll be using the regular e300 11 tooth motor sprocket and 55 tooth wheel sprocket, so you'll have alot more talk. Much better for gradients. Just make sure the b...

Re: Razor

The biggest worry would be the amount of torque produced from the 500w motor. Assuming you're keeping the gearing the same you will have a much greater amount of torque so it could throw a small child off.

Re: I'm looking for recommendations for a scooter...

Have you thought about buying a cheap razor e300 and putting a 36v 500w motor and speed controller on it with a lithium battery on it. It's a cheap way of getting the speeds you want.
