it doesn'thurt to be to careful , but I am trying to determine the difference from his battery sitting where it is sitting and the fuel tank in a gasser sitting on the CG next to the servos ?
CAP.
PS I would say ventilaton would be a must
Since you asked, these are my thoughts:
A lead acid cell produces hydrogen when charged, which can explode if ignited. NiCd and NiMH do not.
A lead acid cell can produce a lot of current if shorted. The wiring might get hot enough to melt a jug and ignite the fuel.
Several gallons of fuel is a lot of fuel.
Field boxes are usually stored inside the house with fuel in the jugs.
Still, with a little care it should be no problem.
