I don't know the details of what you are using but I have an Adafruit Powerboost and that controls the charge current to a LiPo so that it doesn't damage the battery. There are other battery charging boards that do the same thing.

That's a great idea, I have a few of those boards laying around but most came with very small batteries, so just kind of set them aside.
I'll head to graffiti and look at the specific one you mentioned. My battery was custom rolled for second is 20000mAh.
like STeve, I to am working on a portable solution, but mine is a tablet 1st laptop second.
unfortunately i didnt have access to an awesome case like he found, but im working on it.
until then i discovered a quandry. I have been so focused on battery power, and learned a great deal, that i didnt consider 'mains'.
so i have a great lipo batter setup, and even a way to recharge it. however, what if i wanted to strictly work from ac?
I know in current laptoops, usually you have 1 solution that charges the battery and runs the pc, unfortunately as folk have discovered, leave that plugged in too long and you dramatically shorten your battery life.
what I see in my head, is 1 jack exiting the device, and right now that runs straight to my battery and power circuit, what i would like to do is provide a "slider" switch, that goes from the Jack to the slider then half of it goes to the current circuit, and the other way leads to a straight AC power circuit.
When ac is plugged in you put it in position A, when its not position B and the battery is in line.
anyone know how to wire such a critter or is there one i can buy? ive learned a lot, i just dont want to fry the whole thing.
