You would be surprised at how little hydrogen is required for a flammable mixture. Our forklift charging areas have hydrogen sensors that activate exhaust fans and sounds alarms. Fans speed up at 1% and the alarms go at 2%. My motor home has 4 golf cart and two engine starting batteries in a compartment completely outside the living space. When the 100 amp charger gets those batteries into the off gassing stage the Propane detector inside goes off.
So charge you batteries with a 4 stage charger while sleeping with everything closed and light your stove first thing in morning for coffee.
Yes, I'm being a wise guy but there are reasons that things have to done a certain way.

Jeepers. You guys think I'm a worrywart. No one is going to accumulate enough hydrogen in their van to cause a fire or explosion. Our charging currents aren't high enough, our batteries are too small. That stuff will float out of the van like a ladyfart in a breeze at a picnic.
