Hi

I have built many battery packs up tx and rx packs.

You need a big iron that can solder the wires on quickly but with lots of heat, i use a 65 watt with a large bit.

Rouphen up the terminals with a file.

glue the cells together in whtever configouration you require with a hot glue gun

i use small lengths of 25 amp car wire for the links, make up a short bridge stripping the sleeve off each end and hold the bit of sleeve thats in middle with long nose pliers tin the battery terminal and both ends of the wire. solder one end on while gripping with the pliers then push flat with the pliers while soldering the other end in both cases make sure the wire dosn't move while the solder sets. if it does take off and do again but let the batteries cool first.

once done solder a lead on and cover with heat shrink.

I like to use clear heat shrink as you don't need to take the heat shrink off unless there is a problem ,and not if you think there may be.

Inbetween soldering a particular battery let it cool ie don't do one end then the other straight after. all the pack i have built have been fine except one which ended up with 2 faulty cells this was a aaa pack weather i overheated it or they were just faulty i'm not sure.
