Hi all, new to the forum and am hoping maybe there is a cool way to do this. I’ll give a little background to my project. I’m in the process of finishing a ‘from the ground up’ rebuild of a 150cc scooter. The scooter originally used AC voltage directly from the stator/magneto to power the lights and the AC powered CDI(capacitor discharge ignition) but, I have changed that and am now running a setup where everything is powered from an 8ah powersports battery. So, new and fewer LED lights and a DC CDI. So, here is where my interest for an efficient phone charger comes into play. I plan on using this scooter for food delivery as well as a bit of travel where I’ll be using Google maps constantly on my phone. Because I’ll need my phone constantly charged and working all the time for deliveries, I’d prefer to use the 2 amp charging current available in the 5v cigarette port chargers and the likes.
Now, Im only half crazy and the other part reasonable and I’d not like the crazy part to ruin a longer trip by killing my battery in the middle of nowhere by just winging it and seeing what happens. I would use a bigger battery but, Im trying to keep the weight down being Im already over 200lbs and some of the larger batteries are over 15 lbs (cost more) and then there’s all my gear, tools, delivery items, constant starting etc.
What Im wondering is - is there some form of buck converter setup or a way to take a tiny current from my battery and boost it up to a higher voltage/current? Am I just dreaming? I have no idea how those cigarette chargers drop 12v to 5v and whether that would be better or worse for my electricity needs but, I’m all for learning. The one mysterious component of my setup is the DC CDI. I just can’t find info on the net anywhere for how much current it draws throughout the rpm range. I’ve heard someone say 2 or more amps and others say no where near that. But, that plus a phone charger, starting and all my lights means I might have to step up the battery which I’m trying to avoid. I will however step up the battery if I have too. Any help would be greatly appreciated.
