Pink sections on the right are for vbus connections and 1 thermal resistor. They are like that because get when I was doing the routing in Eagle, it was throwing up Earnest airwire errors for the GND's and at the time this was the o my workaround I could think of whilst working single sided. In the 2nd version I've tidied it up as working on both sides for component placement

Funny thing is I didn't auto route it. I actually routed that myself. And as its my 1st time doing this sort of thing I suspected it wouldn't be all that good. Plus it was only single sided. The 2nd version I'm going at it double sided and @PeterBennett I already move my components for neater routing although granted the section here isn't all that good.

there are 2 vbat signals that meet at the circled via, 1 comes from T1 & R31 via U5 and the other comes from C9, C6, L1, R14, R22, U6 & U5 The via is just there acting as the pin out for vbat which would be on adafruit's powerboost 1000c board. The 2 via's via C9 is due to an airwire for GND that Eagle pointed out so I made that change to fix the airwire error.

@Jsotola woops didn't mean to mention that :-D should of proof read that part. Regarding the LED1 stuff I've already removed that in the next version as I don't require the leds.

@Jsotola, I don't think they are, where did you get that idea from? Regarding the wiring diagram on the board I was merely pointing out the the VBAT pin (circled Orange) all of the copper trails from the components that require Vbat link up in that one spot. My intentions as you mentioned is determining which components and lines from U6 actually require a connection to vbat to recharge, power and check battery level. I know about the line length in schematic diagram is not indication to copper length else my board design would look alot like the schematic design if that were the case.

^ Sorry that's probably a better rephrasing of it. Still lacking in that department regarding knowledge as you can clearly see. :-)

Oh let me rephrase that wording. what I'm meaning to say is when I look at the schematic that adafruit has supplied for their powerboost 1000c it seems there's alot of lines going to vbat. What I want to find out is which ones are actually what I need in my design such as: The battery providing power to the board, the usb micro providing power to recharge the battery and the ability to check the battery percentile level. And what ones I don't require to make the above work.

@MartinF in regards to charging it I will work that out at a later date I plan to probably follow the approach of the likes of anker allowing super fast charging Which should be able to lower the charging time. Also as this is a prototype the biggest reason why I have 20Ah is cause I have a Cree LED involved in the design at the moment which uses 3000mah plus 1100mah from the other components in my later version I end up removing this. Meaning I have roughly only 1100mah to worry about.

@MartinF It was exactly as you said the polarity of the cables was the opposite way around. With a little care managed to pop out the connectors and switch opposite way and that worked. Cheers for sticking it out to the end with me over this.

@MartinF I will give your edit a check and get back to you on how it goes.

Sure give me a sec. Will upload the schematic section for the part of the board that was smoking.
