How hard is it to build a lipo pack from individual cells?

As jhautx said!

If you get cells with al tabs be very careful with them as they break easily. You also need zinc solder and the appropriate paste flux to make the solder stick properly. You can get that from cheapbatterypacks.com.

Just have to be careful and patient, and make sure that the solder joints are good! Not too difficult!

where can you buy the slotted boards that the tabs solder to. I have 2 3s packs with a bad cell, and would like to make 1 4s. They seem easy enough to put together if you have the board.
