How Can I connect This battery

[NeoMetalSonic999]

I have these 2 3.7v batteries, and connected to a protection circuit.
Bottom (blurry, sorry )

with wire

What is the white wire for? And I'd need to see your charger and charging port before I could show you how to wire it, but the negative on it goes to negative on the battery, and positive to postive.

I have the same bc on my battery. I'm not sure what it's for, but it is important.

I think I'm changing my plan, (I don't want to open another post)Instead I am going to solder it to The dvd player, It has thw switch and charger.

So how would I make it go to The N64 too (I have done projects before, but this is my first one on a game console)

Never mind...I Tried it, and the dvd player broke

I am going back with the Ps1 screen, I am using the charger from the screen.
I still need to know how to put on a power switch to the battery.

I don't want to open too many threads,(I saw your N64 project) so what cable do I use to relocate the cart slot.

Cable? I just used computer IDE/ribbon cable. As for wiring up the psone charging port, the metal parts on the side are ground, and the pin in the middle is positive.

It doesn't really matter, it's just wire. Keeping it small though is good to do.

That white wire is battery common (get it? BC?). It goes between the two cells on your battery, so yes it's important for that protection circuit to work properly.

I am unable to tell because the picture is so blurry, but it looks like Load+ and Load- is somewhere on the back of that board.

Ah so it's the ground for everything. When I removed it from mine I only got 3.7 volts out of my 7.4 volt battery

[eurddrue]

OMG! No wonder my protection circuit isn't working *facepalms himself until he gets a nosebleed*

[Erlex]

Well no, its not ground. 7.4v batteries are made up of two 3.7v cells. Essentially two batteries. Check out this ever so awesome paint diagram to see what I am talking about.

That IS awesome.

Oh I see, common makes me think of common ground. I guess in this case it just means common battery connection.
