Re: Battery connections
Thanks everyone for all the suggestions. My team has decided to use a compression lug (bluedie374) COVERED WITH heatshrink tubing. The full pole connection will have to be isolated. Then we'll validate the electrical resistance (should not exceed milliohms), and then we'll do a pull strength test. The tool used for compression is taken from HomeDepot.

Re: Battery connections
I've used this crimper with good results. The dies are not perfect and their sizes are weird and it flattens the hex a little and puts "wings" on the sides of the crimp, but it goes make a good solid connection.

Re: Battery connections
Crimp, solder with a blowtorch, repeat.

Re: Battery connections
A proper crimp does not need solder; indeed, the 'right' crimp is made worse with solder.
That being said, a 'pretyty close' crimp can be improved with solder. We have used the crimping die on these pliers with great success. Two students squeeze it shut, it does take some effort. |

Re: Battery connections
I use a very small screwdriver or awl from the "contact" side of the connector to push/pull the spring out of the way, then pull the wire and pin out the other side. It's easy. I even used a paper clip once.
