I’m concerned enough about the 2-3 reported fires here on the forum that I’m considering adding a pressure sensor to my 16-cell LiFePO4 battery pack.
I’ve already got my single-line of cells in a 300kgf clamping fixture which I’m setting to ~12psi @ 50% by counting turns on my 8 calibrated springs so adding a pressure sensor should be straightforward and inexpensive: https://www.amazon.com/dp/B07S9YJH8C
I’ll probably just do this and monitor the pressure range I measure under ‘normal’ operation before deciding what I want to do with this pressure signal and how to use it for an extra level of protection.
Has anyone else done anything like this?
Once I know what the max pressure is at 100% SOC, I’m thinking I’ll run the pressure signal into a threshold circuit controlling an alarm and perhaps eventually a fire extinguisher / preventer.
Any thoughts & advice appreciated…
