    Batt Magnets, good enough?

    I'm considering a small mod and I'm jealous of every mm3 used.
    My question is for those people that have used magnets to hold the battery connection in place, is the connection good enough to reliably draw a few amps from the battery?

    16340 or 18350 in mind here.

    I have a 4nine clone that uses a magnet to contact the battery to the switch and I use a small washer as a spacer. This mod seams to be the best hitting out of any mech I have tried but I haven't checked volt drop.

    Cheers

    If your using the magnet as clamping mechanism to hold the contact to the battery it will work fine.
    You can even insulate the magnet if you want to eliminate the magnet from the circuit.
    If your using the magnet as the actual contact then there is a chance the current will demagnetize the magnet quicker than it would normally.

    I have used magnets in a few of my Heath Robinson setups and they work well. For a while in the early days magnets were the go for extending the length of many cells to get them to work in a few bastard size mods. The main issue is when soldering to the magnet, it will lose a whole bunch of its magnetic magic. The work around for me is to solder to a thin magnet, then piggy back another thin magnet to the soldered one. Nufin wrong with abusing magnets.

    Epoxy the magnet to some thin copper strip maybe?

    I was thinking, battery connection, copper contact, glue, magnet. Pretty much as described here.
