Hi W
The MiniBMS bypass resistor is a 5w/4.7ohm power resistor (cement type with
axial leads). SMD (surface mount device) was probably meant to describe the
other devices on the board. The large resistor on the MiniBMS (the version
I've worked with only has one) gets hot in use, so spraying a coati

The miniBMS units have two large SMD resistors that dissipate up to 0.5 amps of
current while top ballancing, and get quite hot to the touch when doing so. No
heat sinks on them however, so I don't know if that would be "too hot" or not.
4v at 0.5a is 2 watts; that's a
