Looks like an interesting and reasonably economical board. Unfortunately limited to 500ma and some of the things I run need two amps. Be good to be all in one. The Kendrick I use is good for heater straps and fans but limits the output so not much good for coolers .
I have tried a Jaycar voltage converter so the 12v can be throttled to 10v to save battery power but it requires a big heat sink . Perhaps the heat sink can act as a dew heater using the waste heat and a fan.
