Re: Soldering Battery Connections
I have done like you with partally filling the fitting but the fitting needs to be checked so it is not too large. You want a tight fit but not too tight or too loose. If it has a lot of air between the outside diamter of the wire and the inside diameter of the fitting then the solder could be used to fill it but I would not want it that way. Most items on a circuit board that the leads pass through fit the leads and are just slightly oversized so there is minimal solder bridging the gap. The reason I prefer crimping then soldering is the voids or airspace is minimized for in my mind anyway, better transfer of power.
I prefer crimping then soldering then either heat shrink tubing covering the joint or the push on rubber boots. I have used a propane gas torch before but switched to a Mapp gas one but normally on the ring terminal ends I'm heating up the end of the ring enough to where the crimped area gets hot enough for solder to flow into the joint and out the other end where the insulation almost butts up against the crimp connector. I have to watch how hot I get it. Hot enough for the solder to flow into the joint, not hot enough to do damage to the insulation (but it does become softer and hardens back up after it cools), and not hot enough to discolor or melt the copper strand wires.
If you ever want to see if your solder connection or work is fully filled do a wire and fitting as a test and then cut it apart for inspection.
Soldering takes practice just like other things. When I was learning to weld I cut many a joint apart to see how well I did.
