Waterproof a lipo pack???

[RCvolt]

Got a couple of lipo that got wet. Stripped the wrap, patted them dry, sat them under a fan overnight and had them sitting exposed for a week. They are as dry as they are going to get and the heat shrinks arrived today. Can I use plasti dip (pictured) to cover the ends after the shrink wrap has been applied? Is waterproofing advisable? Should I be worried about possible moisture retention?Thanks!

I think we had a thread about it here somewhere and it basically was saying that "sealing" the packs is not advisable because water WILL FIND A WAY IN and it'll not dry, creating rust and potentially a broken tab or a short somewhere...
so my advise to you is, seal the hull well not the battery packs.
I personally sunk many batteries in the water, made sure to dry it out nicely and they worked just fine, you'll find that many people have done the same.

Got it I'm glad I got 5 feet of heat shrink


Thanks!

Rust? You mean oxidation right. :)

insulate & seal'em

Hi Mate ,

with my 32' Cat i have insulated the 2x 4s parallel wired & sealed the packs with silicone where the wires protrude through . Considering the amps i run does not allow for over heating , i find this to be a most effective measure in maintaining battery intregity . Works for me anyway .....

All the best in R/C Boating
