Hydrogen outgassing, electrical consumption and the myriad code requirements much venting over the need for ventilation
In other words, if a 48 volt ( 24 cell) battery experiences one shorted cell, the float voltage is then ‘seen’ across 23 cells and not the shorted one. HVAC systems with fresh air economizers generally provide enough fresh air ventilation that exhaust is not needed. Neither the International Fire Code (IFC) nor NFPA 1 require that battery spaces have exhaust fans or ducts , however many AHJs insist upon them.
