Is anyone using a hydrogen detection device to turn on a vent fan in their battery room? My batteries and electronics are in an 8'x12' well house. The well house is close to air tight. I will usually open the door during the absorption stage but I am not always home to do so. I have 16 Trojan 370AH batteries charged by 3KW of solar.
The cost of a hydrogen detector is steep at around $1000. I'm looking at the 'SBS-H2' and 'HGD-2000'.
Any other ideas to control hydrogen would be appreciated.
