waterproof lipos

[tundrafan01]

Hey guy's was wanting to know if there were any brand's of lipos that are waterproof. i want to ruin them in my emaxx so 2cell is as big as they can be thanks guy's tundrafan.

[oscodawave]

why do you want to ruin them?

i think max amps are the only waterproof lipos

they all have to be waterproof to be air tight, cause venting to atmosphere = FIRE.... combustible when exposed to oxygen.

Ya, but the plugs and and all the contacts need to be waterproofed too. Each individual cell is waterproof, but they are connected to each other by exposed tabs, and natural water/rain water/etc is conducting, so it will short out the cells.

If you buy some big heat shrink, you could remove the existing heat shrink, cover all the contacts with hot glue or silicone sealant or something, and then put new heat shrink on. You could probably make any pack waterproof by doing this.

Whether they do this from the factory already, I don't know.

A dip in plasti dip will waterproof the ends. Normal lipos are waterproof naturally, and the only problems are the cell interconnects. Although I wouldn't really consider it an issue. Only the highest mineral content water would conduct anything between cells, and it would be a very small amount of current.

I was wondering the same thing, that's good information to know.

I have a related question. What plugs are the most waterproof or resistant? I hear the traxxas ends are pretty good but is there anything better or anything I can do to improve them? I normally use deans or XT60 connectors for minimal resistance but would rather waterproof for my Slash.

Or is this pointless for some reason I'm overlooking?

Plugs aren't really waterproof unless they are sealed, and no hobby ones are sealed. What you would want is the most distance between contact points that have the largest voltage difference- the main power plug. Traxxas plugs may have a bigger distance between contacts as opposed to deans. I never had problems with deans in the water though.

could use liquid electrical tape also but plastic deep seems more durable.

There is no such thing as water proff with batteries. Doesn't exist. Some manufacturers advertise it, but it's a sham. It is impossible to water proof a battery, and further more, water proofing is dumb. You want them to breathe so they dont corrode. I dunk lipos all the time. Never worry.

Tis true. If moisture gets trapped under the waterproofing it will cause tab corrosion and can eat at the cell glue. The best method for pack protection would be a spray of dielectric grease before a run, and a cleaning with low velocity compressed air afterwards.

I was just thinking the traxxas ones would be best because the positive and negative are actually separated by a plastic wall. The water would actually have to go around 2 corners to contact both at once. So far all I'm doing is running a Slash 4x4 in snow. Maybe just fill the female end with di-electric grease before plugging them together. Either way, you guys seem pretty confident about dunking your lipos, puts my mind at ease quite a bit. Thanks....

[tundrafan01]

okay thanks for all the advise where can i get this dielectro grease. stuff at thanks and how much are two decent lipos gonna cost me i want run time and some decent speed.

[JohnRobHolmes]

Auto parts stores carry it in grease form, but probably not aerosol. It would be messy, and probably not worth the effort and mess involved really. Take Chris's advice and just run em!

[t-boner]

What about a balloon?

[JohnRobHolmes]

Or a condom.

4 5000 mAH batteries are anywhere from $220 for 4 to $500 for 4. So it depepends on the brand of course. Personally I would get 4 venom 2 Cell 5000 mAh.
