batteries - What is a good melting point for a lithium battery contact fuse?


Tesla uses a fuse on every battery for their cars, and many fusible alloys melt from 50 to 90 degrees.


because the fuse is welded onto the battery it wouldn't matter what the fuse current was, you could have a large wire capable of high currents which would melt only when the battery rises over a certain temperature.


What would be better, a lithium battery welded fuse that melts at high currents, or at high temperatures?



What would be ideal fusing temperatures for both scenarios?

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
