Safty or Crazy

I did post this earlier on another form in here. I apologize I cannot figure out how to delete that one. Anyway this is what I have at this point. Hopefully next month I will be purchasing my rear 1000w. System and a 20 amp hour lithium battery pack. I am integrating a 12-volt motorcycle battery in the middle of the frame which still allows me to Pedal. This will run my LED headlights blinkers brake lights and parking lights. I have already installed the blinkers I used a 3-way toggle switch for the controller. For the brakes I simply added a returnable toggle switch at the disc brake arm. I will also be adding a headlight to the front fenders that I am building right now. I will be installing smooth head bolts so it doesn't look so tacky and also painting it to match the bike

Hi David.

If you will have a 48 volt, 20 amp hour lithium-ion battery, why not wire in something like a 48v to 12v step down converter?

That one is a quality waterproof unit, but there are others available, some smaller, depends on the power needs to run your accessories. It would be a lot lighter than a motorcycle battery and having one battery to charge would make life with your ebike easier.

@J.R. you are always helpful, thank you for that. I have tested the electric system with the 12v and it will need to be charged probably every 3 months. The LED system I have on it takes very little wattage. And as you know I'm still learning how to do all this stuff. But I'm enjoying it as I go. I've already got all my wires ran and everything set up, I did that later today. As always thank you for you're knowledge!

Be careful about drilling random holes in bicycle components. You defeat the engineering of the part and introduce a stress area that can now crack.
