Re: BMS problems

Re: BMS problems

I almost forgot to ask but my bms has a B- and a C- port so would the wiring still be the same?

also what rating resistor should i get (watts) or does only the resistance amount matter?

Re: BMS problems

thanks that helps. first, is it fine if its a switch? like on/off switch.

2nd, out of curiosity why is there a resistor? to keep the connection from shorting out through small power getting through of something?

Re: BMS problems

im not to keen on wiring and many electrical things just the basics. if you could maybe provide a diagram or describe how I would wire that it would be of great help.

Re: BMS problems

Re: Building a Powerful Ebike

I see, I didnt realise that it takes THAT much more power just to go a few miles faster. So then by that I would be guessing upgrading the motor to one on leafmotor is almost pointless. So i guess the only thing I really would need is a battery upgrade in the future also is there a chart or somethin...

Lol 18miles on a 20Ah battery? That battery is definitely not 20Ah
I thinks the motor just isn't efficient or that I weight a lot and the bike with everything on it also weighs around 80lbs and I blast full speed all the time

Re: Building a Powerful Ebike

The kit info states it's capable of 34 mph @ 48V, but is restricted to 24 for street use, and should be capable of more @ 52V especially with the cells you're using. Have you removed the restriction in which case they're information is faulty? I ask because my YESCOM kit goes 33+ mph with a 30 amp ...

Re: Building a Powerful Ebike

Re: Building a Powerful Ebike

thanks. now I have an idea on what to look for. I did find some other bikes But only front suspension. I have 3 Questions. 1. is there a limit to smaller tire sizes on a bike made for 27.5 like putting 26" or 20" rims on it? 2. With the frame shown before and the thread with the battery box. what wo...

Re: Help with bikes

also could I use a fat bike with something like the Luna Lander Fat Suspension Fork? since the fat tires would also provide some rear cushioning to make up for no full suspension

Re: Help with bikes

sorry about that, I'll stop. also I saw this thread https://endless-sphere.com/forums/viewt ... =1&t=85489

and thought maybe this might work with this frame https://www.ebay.com/itm/303003706585?ul_noapp=true what do you think? or would it be a bad idea because it would hit the front tire?

The reason I did not want to get any of those dirt bike looking frames is because I will be using it to get around everywhere at not always for around 90% of the time go more than 30.

Re: Building a Powerful Ebike

In that case Would 3000w be enough? The kit I posted says 150nm but is it? or more closely to this one in terms of torque: https://www.ebay.com/itm/26-1500W-Rear-Wheel-48V-Electric-Bicycle-Bike-Motor-Conversion-Kit-Hub-Cycling/322269304808?epid=1286064734&hash=item4b08bf57e8:g:34AAAOSwXF5cEfR7:rk:1:...
