So I noticed that RCT tank has the same air hole down at the bottom of the battery connector like most other 510 tanks and carts for auto battery’s sake. Now that I’m on the eGo, this serves little to no purpose for me, but it does leak a tiny bit. Though this leak doesn’t interfere with the current passing through, it does corrode the threads of the tank’s connector and just annoys me enough to try and plug it.
And I did so via a small circle of aluminum tape.
This displaced the 2 little air holes a tiny bit and blocked off the main one, so the draw is a bit harder, but it seems to conduct better without that drop of liquid being in between contacts and there’s definitely no more corrosion going on.
