So as some people know, Kelly has as set of eBike specific controllers (KLS-S). I've been looking at them, as well as other controllers to get a specific set of features. Anyways, I was going through the options that Kelly offers for these models, and one of the options was waterproofing. Awesome I thought, I figured they would seal all the joints and connectors with a silicone sealent, like RTV or something.... Nope.
Kelly Waterproofing is .... "We will fill the controller with silica gel to get waterproof. The material is V-0 rating for silica gel"
Now, far be it from me to be an expert on waterproofing something, but silica gel is a dessicant. It's essentially meant to prevent moisture in the air from condensing onto things, by trapping it before it has the chance to condense. It isn't meant to be used to waterproof anything, it isn't meant for anything beyond humidity in the air.
I thought this was funny, in a sad sorta way, thought I'd share.

It got me thinking though, has anyone ever sealed their controller and then filled it with a non conductive fluid, like mineral oil or PDMS (silicone transformer oil), for both cooling and ingress protection?
