I could deal with custom leads, but wasn't sure about timer. I looked at a few of the welding machines on the bay and zon. Reviews are all over on the cheap Chinese machines, and unsure about battery operated ones.

Do the LI-Po cells charge the same or do they need a completely different charger? (In other words are they swapable with Lithium Ion?)

I am trying to keep tool buying to a minimum since I have quite a collection already. But it would not hurt to rebuild some battery packs. I have a $100 pack that has bit the dust and always like to fix things. Guessing it uses 5 cells and it is a 2.0 AH.

Glad to see you are still around !!!
