LIPO battery 14AWG wire connector, will this melt the wire?

So I was hoping that someone could clear up some confusion on my end... So I've got a controller that will draw max 30A...

For a cheap experiment, I could wire 2 of these together right?

Re: E-bikes kit installation

I just looked it up. Boston to Brattleboro is a 2 hour drive. It might be worth the drive if he has good prices? I think he charges whatever dillenger charges for the kit and then just some $ to install it for you. Burrows Specialized Sports Address: 105 Main St, Brattleboro, VT 05301 Phone:(802) 2...

Re: New to eBikes! Appreciate comments on this configurati

OK, here's what I'd get. Then strip the motor out of the 26" wheel and lace it into a decent 20" rim. And not one of those weak narrow rims, but one that's 32mm wide inside. That way you have all the other parts you need, The controller that comes with this kit will be either 26A or 30A m...

No, the BMS should be permanently attached to the battery, the only time you should disconnect it is if you are going to put the battery into long term storage. So that is monterous lifepo4 pack?

Re: Video of 48v20ah Lifepo4 battery, 3 pieces?

It looks like the "computer" is the BMS which stands for "battery management system". Basically the BMS makes sure the cells within the battery remain balanced, there is a wire from each cell (or group of parallel cells) to the BMS so it can monitor the voltage of each cell in t...

Re: New to eBikes! Appreciate comments on this configurati

Normally 1200 watts is considered a lot to put through a fork but we have (at least I) have no idea what your recumbent bike frame looks like. The other thing I noticed too is that the controller that comes with the motor only has a 20A controller. So if i use a 52V battery, I'm at most going to ge...

Re: New to eBikes! Appreciate comments on this configurati

30 amps max, and 20 amps continuous spec battery will work with that kit. Of course, a larger battery would be better, because with more ah, it can dish out more amps. Again, cruising full speed will likely be 12-15 amps. Cool, you've tried that motor... Just to clarify you mean this one I said in ...
