Will this get too hot or...??

[Zbugsii]

I have found a plastic water proof box that I plan to mount my OverKill BMS within. It is a 7.9 x 4.7 x 2.2 inch box and I will be using glands to run the cables through, thus no air circulation and such.

My configuration will be two banks of 280aH batteries with two Overkill BMS, each in parallel. My load will be less than 100amps at 12vdc.

These will be installed in a covered battery box on the front of my RV, but not completely water proof. I have limited room and have to put the BMS horizontal on top of batteries.

So, will it get too hot? Should I try to make some ventilation? Or do something completely different?

Any thoughts in this regard are welcome.

At 50 A each, assuming they share, maybe OK. Why not run a test and see how hot they
they get, the app reports the BMS temperature. My test of a single BMS at 100 amps for 2 hours showed a 9 deg C rise (with the BMS on the bench)
