Don't use magnets with li-ion cells! Dead-short danger!
I've been seeing an alarming number of posts talking about using magnets with flat top li-ion cells to make contact.
add dab of solder to circuit board to solve contact issues. don't solder to li-ion cell, unless you really know what you are doing.
Don't use magnets with li-ion cells! extreme danger of creating a dead-short!
side impact will cause magnet to shift and possibly bridge to ground causing a dead short. a very bad thing to do with a li-ion cell. this could lead to venting with flames!
here's pic showing magnet shifting with polaris' battery carrier. second pic show damage to NMH cell.
only using these shots to illustrate magnet dead-shorting. if this had been a li-ion grounding out, results might have been different.
this warning also goes for Firefly 1 & 2 and CNC 123 owners using li-ion cells. sandwich is held in with metal circlip, which could dead-short to R123 with wider nipple. remove circlip and use Oring to secure sammie.
