Follow the example in the pictures.

Make sure the B+ and B- go to the LiPos obviously and the Out+ and Out- go ... well out to the equipment obviously. The Out wires in my photos are the fatter brown (B+) and blue (B-) wires, which I soldered to the reds (+) and blacks (-) of the battery holders respecively.

Parallel up all of your battery holders, connect them to B+ (all the red wires from the battery holders) and B- (all the black wires from the battery holders).

Use tape, hot snot (aka hot glue) and heatshrink tubing to keep it all neat and tidy, and minimise the risk of shorting things out. Add an inline fuse and a switch if you want to be a little more sensible. I didn't bother, relying instead on the protection offered by the charging board. I like to live life on the edge... although I must admit I charge the things on the tiles in my fire hearth just in case of unexpected smoke.

Just to confuse you I also have red and black wires going out to the equipment connectors. Just dont get them mixed up or something will go fazoosh!!

Once you have double checked everything, plug in the USB connector and your cells will begin to charge. Keep an eye on them watch out for smoke, flames, singularity events or other dangerous problems.

Once charged, disconnect from the USB cable and plug in to your camera or whatever. Be aware that some of these usb charger boards have a nasty habit of deliverying the full +5V to the equipment when the batteries are fully charged, so i would suggest charging with the equipment disconnected if you are at all uncertain how well behaved your board is. Some 3.6V items might not appreciate +5V.

One final warning. When fitting the cells prior to charging for the first time, ensure all of your cells are within a few tens of milivolts of each other. Parallelling up an unprotected fully charged and fully discharged Lipo can be a *very* bad experience. Things get hot, fast.. very fast... things go pop... don't say I didn't warn you.

Also take care not to fit any cells the wrong way round, this will also make for an interesting time and lots of strong language when previosuly cool safe looking cylinders weld themselves instantly in to place and start to hiss like a bunch of hot demented vipers.

There is a reason why LiPos use charge protection circuits.

On a more positive note (pun intended), once you have charged up a bunch of cells in parallel for the first time, they will always stay at the same voltage as each other, so you shouldn't experience any major issues after the first charging cycle.
