it has a solder tabs option when you buy it, im going to use the tabs.
they also have the balancing lead http://www.all-battery.com/jst-xhv23...2cellpack.aspx
if you dont know how to hook them up, the red / black goes to the positive and negitive (of course) the white one goes on the solder connection that connects the batteries in series
they also have plugs and shrink wrap to finish it up

a few other things i found at all-battery.com that can be very useful
3 plug switches (the standard rc switch) for 1.50, i bought 5 of em to see if they are any good, if they arnt ill use them in noncritical applications http://www.all-battery.com/receiver-switch80183.aspx
and a dc-dc regulator w/ adjustable voltage so if my glow ignitor dies i can use it to drop my voltage down from a 12v (or 14.4v starter battery)
i can also use the thing to convert battery power directly to a laptop/cellphone/charger/ect without useing an inverter.

its only 20 bucks so i figured id give it a try, their are so many applications for it.
ill let you know how each one worked out, if the life and/or switch workes as intended that could mean some good savings.
