Re: DC-DC converter from 48V to 6V for E-bike light?

I use the 6v to activate a solid state relay that can activate with anything from 3-32 volts. http://a.co/8KvbrY2 That way you don't need another switch on your bike and use the built in headlight feature. https://images-na.ssl-images-amazon.com/images/I/41viIpmRjcL.jpg I ended up using it on a lig...

So, what solution is better?

Something like this:

DC-DC converter from 48V to 6V for E-bike light?

I got a Bafang BBSHD motor, which has a light cable output of 6V 0.5A = 3W which isn't enough for any decent light. I bought a really great e-bike light 6V that requires 12W, so 2A output instead of 0.5A. For this reason I think to connect it directly to my 48V battery using a DC-DC converter. The t...

Re: How To, 50A BBSHD Controller Mod

Sorry for the interference, but isn't "Ludicrous" version just a Luna internal name for a controller where they switched out the shunt (and maybe also replaced aluminum case IIRC)?

Headlight problem on my BAFANG BBSHD

Hello, I bought a headlight for my BAFANG BBSHD, I connected it to the light cable but it keeps blinking all the time. Manufacturer claims there are 3 modes: daily (1.6W), nightly (12W) and auto with ambient light sensor. But even if I try to switch, it keeps blinking! Is it possible there is someth...

Re: Sur-Ron - New Mid drive Bike

The most recent batch of bikes we have imported all have Fastace forks, but no longer with the air chambers. The new Fastace fork is spring only, and the factory will no longer supply Fastace air forks. They are now also offering DNM USD-8S as an option, alongside the RST Killah and Fastace ALX13RC...
