Re: Type of wire for phase wires

Higher frequency favours multi strand wires. So the more strands the better for mid drive. Usually multi strand wires are softer.

Re: switching to a new 4 prong battery from 2 prong?

More connectors are usually put for better power transfer. Load better spread = lower temperature.

Both sides of the connector have to have 4 for it to matter. So 4 on one side + 2 on the other = 2 connectors.


In short, NOTHING CHANGES.

Re: switching to a new 4 prong battery from 2 prong?

It depends on the connector, it's capacity, and the system power.

It will probably be ok with a 250w motor, but most 250w motors aren't actually 250w.

If you want a real refund, either contact paypal or if you paid by credit card contact your bank and file a chargeback claim.
You will need to supply evidence on you sending the package back and the seller recieving it.

Argh. I was looking at alternative to spot welding. To use the epoxy to hold contacts in place. I've found a few more older threads about it but none cover the connections. They're all SW.

Yes it is spot weld like any other. BMS goes in and gets filled in too.

If you are making it for someone else, make sure it is either rain proof, or that they understand it isn't.

Re: Covering 18650 cells with epoxy resin

No need, epoxy is already insulating, in motors they use it in addition to motor varnish.

Guy in UK already does them to order.

Re: Charge bike with gasoline generator While driving?

Yes you can string 3 SLA 12v batteries to get 36v. They charge slowly though. Good for 30km.
300km a day if you can't afford $250 is a fairy tale though.

Re: phaserunner xt60

You are not supposed to plug and unplug the controller every ride. Use the ignition switch or display on/off, or battery on/off switch. All of these are low power switches and will not degrade after hundreds of cycles. You can use the battery switch to depower too if you take it off for charging.

Don't go centrelock. They are a lot more expensive and no cheap alternatives. I would easily choose a different hub if I had to, proprietary standards suck.

Re: samsung 40t 21700

For 12.5A per cell peak you don't need high drainage cells, you would be fine with high energy cells too, like 50e. The 40t can do 25a cont and a bit above it peak.

If you are going to go trough the trouble of replacing it, DNM is not much better, not worth it.
If you are replacing it get a used rockshox boxxer, marzocchi bomber 380 or fox 40 on pinkbike.

If you already have it, it is a done deal, the GNG drive has most of the cyclone kit's bugs fixed, so it is as good as you can get otherwise.
