Ok...Once again I've confused myself thouroughly...I'm wanting to make a 2s2p 18650 li ion pack with this PCB: http://www.batteryspace.com/pcbfor74vli-ion1865018500batterypacks7alimit2round.aspx
and a 3 wire JST style balance lead. I want to make a standard flat pack with the batteries side by side. I've looked at this site http://scriptasylum.com/rc_speed/_lipo.html and understand it but I'm having a mental block on how to wire everything with the batteries side by side instead of end to end. A simple diagram would be awesome!! Thanks

i used that exact pcb before, 1 advice, be very careful when soldering, all components are tiny and surface mounted, if you overheat the board some may desolder, but you wont see it, it might be just 1 leg of ic come loose but it still be kept attached by other 5, yet the board will not be working, try to limit the time you heat the contact plates to as short as possible, and use as little solder as possible.

Thanks!! Now when I figure out where to hook the 3 balance leads in I will be good to go!

it is on the drawing, staring right at you.
2 wires that are marked charger load are not those.
 
Ohh...Ok...So could I hook the balance tap leads directly to the PCB at B-, B+, and Com or would I be better off just hooking into the wiring at the right spots to keep the chances of ruining the PCB down? Thanks again!
