Battery Box

Tromboman · Feb 16, 2020

Any suggestions on how to seal the holes where cables enter the battery box? Other than my current idea of a crap load of silicone sealant, of course. With all the huge puddles around at the minute, I'm slightly cautious of any water making it's way in there.

Isn't there a drain hole? Water in the battery box shouldn't be an issue. Unless there's other electronics in there too?

Just make sure the drain holes / slots are working in the bottonm and you should be fine, Mine is often submerged in mud and water.If it gets muck in there you can always hose it out.

I've used glands and plastic conduit on mine and I also used them on the underseat drivers box (110, no fuel tank) cos I've got leccy stuff there too.

Got a secondary fuseboard in there + relays for spotlights etc... so I'd rather prevent anything getting in there

Pretty sure battery boxes shouldn't be sealed because of the risk of gas building up.
Maybe a deflector shield is the better way to prevent water ingress?

You fit a breather, much like an axle breather but it runs downwards from the floor of the battery box. A lot of sealed batteries have a vent tube too.

OP, just make sure all your electronics are weather sealed as best you can, the battery box will get wet no matter what you do unless you strip it all out and seal it all properly.

Never understood why battery vents are always at the low point, when hydrogen is lighter than air

I dont know either, perhaps Im getting confused with gas cylinders!

but hydrogen is not toxic (unless it’s all your breathing) and let’s face it the defender is hardly air tight that you could fill it.

I guess you could blow yourself up though

where as H2S from an overcharging battery is hugly toxic. (That’s heavier than air)

maybe
