Can an MN27 alkaline battery power my 12 V, 0.16 A motor?
I have two motors in parallel rated for 12 V at 0.16 A.
They generate a small 14.4 pounds (64 N) of force combined at a slow speed of 30 mm/s.
The motors open and close a door for this project.
The ...

Two 14S Lithium-Ion batteries have different charging speeds: the smallest is slower than the higher capacity one
Long story short: I built one 14S battery last year, using Molicell P42A cells. 6 cells in parallel for every series. So, around 58.8V total voltage on the battery.
Recently I made another battery ...

Nominal voltage of supercap
Is it possible to replace a supercap e.g. an FCS0V224ZFTBR24 which is a 3.5 V type by its equivalent with a higher voltage (5.5 V), the FCS0H224ZFTBR24? The datasheet of both types is here.
What will ...
