LVC/LVA for a 1 Cell LiPo?

[rawfuls]

Oh, okay, so it'd just be like a standard 2s lipo.

As in, I have one set of wires (let's say JST for now, smaller ones), that go to the USB charger.
then I have another set of wires, to plug into my charger to recharge?

Would there be any way to keep one set of wires, since it'd take less room in the little Altoids tin I'm keeping everything in.

If not, I guess I could go with two sets.

You have the battery going into B+ and B- then you have the P+ and P- connected to the JST plug, which you plug into the MintyBoost, and also use to charge the lipo, you only need the one JST plug.

Look at your RC lipo packs, you have a deans, bullets, etc. on there and use it to charge and discharge the pack. Same thing here.

AHHHH
Now I think I've got it!

So, pretty much, this:

[suicideneil]

The load is the item you are charging ( charger side of the circuit ), the battery will be the power supply ( a single lipo cell to power the charger ).

Seems like alot of extra complication when you can just buy plug-in usb chargers that take a 9v battery for example, or a lithium cell built into the case for an iPhone to extend its air-time...

Ahh, but what's the fun in that!?

Don't take me wrong, I have about 2 or 3 iPod/iPhone chargers, prebuilt, it just seems... too easy...

I mean, I like easy, but making stuff makes me take pride in it!
Besides, people are buying my chargers off me like a fat kid and cake.

EDIT: but anyways, the diagram is correct...right?
Of course, I'm gonna try making the simple way (board and AA's), then order the PCB, and another lipo w/ one built in, and switch off..
Hehe, looks kinda like a bomb in class.

I am pretty sure you have it wired wrong there Chadworkz. I might be reading which contacts are for which labels, but I think the batt and load have a common ground or negative.

[rawfuls]

God, now I am so confused.

Isn't that exactly the same as the diagram above though?
It has the same common ground, just that circle load is.. uh..

Chadworkz diagram is correct, the one zeropointbug drew is the same but drawn a bit differently. They are both right.

[rawfuls]

Chadworkz diagram is the websites diagram-

So, just making sure, for the umpteenth time, the diagram I drew is fine?
Just thinking everything in my head on how I'm gonna do it. :X

[simplechamp]

No the diagram you drew is wrong, the JST connector needs to be across the 2 left-most pads, the battery connection is correct though.

Across, as in both of them? So over P+ and B+?

[simplechamp]

Look at the original diagram from the site, the one Chadworkz posted. The battery goes to the far left and far right pads, and the JST plug goes to the 2 left-most pads. You just need to make sure the polarity is correct, and they are labelled on the board.

The original diagram is drawn exactly as you need to wire it. The symbol on the top represents a voltage source (in this case a 3.7V lipo) and the bottom says load/charge, which is where you have the JST plug to connect to the charging circuit and also use it to charge the lipo.

[zeropointbug]

That labeling is horrible. Which diagrams are each person talking about? One is flipped around the other way.

The manufacturers diagram don't line up with the labels IMO. The big one is batt +, the one next to it is load +, and the far one is common ground... that's just the way I am reading it.

[rawfuls]

Would it be this way then?

Ding ding ding! We have a winner!
