If you have been using Li-ion batteries long enough more than likely you've ran across batteries that a low profile flat top that won't make a connection with a second battery when both are placed in a laser host....

In the past the fix has been to buy small thin neo magnets and place them on one of the batteries in-between the two batteries that won't make a connection, Well I have what I think is a better solution to the problem !
Simply flow a little bit of solder on the surface of the positive pole on each battery and problem solved for good !

No more magnets to buy and get stuck to everything but the battery, No muss no fuss !
BUT there is a catch ! To do this correctly requires a very powerful soldering gun ! I'm talking at minimum a 260 watt Weller soldering gun !

The reason for this is you want the least amount of heat being soaked into the battery or you could damage the cell, The trick to doing this correctly is a ton of constant heat focused to the surface to where the solder will flow for just a few second and done and gone !
It's just that simple and you will never have to mess around with that battery again !
Now if your at all concerned with the electrical contact surface of the slightly rounded surface of the solder and would like a more broad contact surface simple drag the solider surface across a sheet of sandpaper a few time and your done !
Now let the barrage of criticism begin ! lol
