air inlet at walls
(OP)
I have a battery room with 500 L/s exhaust fan. This room is cooled by decorative split unit. The thing is, there is no make up air provided for the exhaust. I cannot put air handlers as there is no space for it within the building / room. Can I just put air inlet (sand trap louver with filter) at the external wall of the room and additional split unit to cool the additional load of the entering hot air? The outside design temp is 50 degC.

if you have lead-acid batteries, NEC and other codes are concerned about hydrogen. Other type of batteris amy have other issues and can explode/combust. so this may require some more thinking than just the air intake.
for batteries, you don't want them to get cold as they lose capacity. Depends on your climate.
You din't provide a lot of information.

At some point the EA fan isn't strong enough and you can't meet your 500 l/s. then you need to create large opening to adjacent spaces, or provide Make-up air.

Also 50 deg C ambient conditions is very high! I would consider an air to air heat exchanger to reduce your AC unit load.
