Been looking at getting my spot welder sorted out. Powering it being the challenge.
I came across a battery booster pack which I bought for about $75, which I thought wasn't bad. Turned out I rocked up the first day it was being sold and the price was wrong. Next day it was $100. OK, that's a win. Has a built in torch and can be used as a USB power brick.

My interest, however, was in the high current connector between the battery pack and the control module with the clips. Did some poking around and found the pin geometry matched the XT90 connector, so I bought some. Tried the male on the control module - and it was firm, silky smooth and PERFECT!!! It felt soooo good. I don't think I've ever been so impressed with a plug and socket connector before. I have every confidence it will handle the current required.

BUT I need to use the female connector to connect to the battery pack - and it has to fit into a receptacle which has some physical constraints....

The yellow connector has to fit into a receptacle that the blue connector does.
Sigh. Could be worse.
