Ventilate a LiFePO4 battery space on a boat?


 

I think I know the answer, but just in case I’m missing something, would it be advisable to provide ventilation to a LiFePO4 battery space on a boat? Active, passive? I know they are designed not to vent gasses, but the question came up and I don’t have a definitive answer.


 

The only reason for ventilation I'm aware of is for temperatures.? Passive (or even none) might be enough, depending of battery capacity, expected charge/discharge rates, and what else might be in the same space.? Short answer is that LFP cells won't 'outgas' except in extraordinary conditions.? Similar to an SLA battery in that regard.
