    I would not recommend running a lipo in any wet conditions. I have a lot of snow where I live so I just put a rubber ballon around it with a rubber band around the plugs. The balance plug is the thing to worry about. I have had no problems doing this. Not sure about the esc let me find out.

    Do not get lipos wet.

    Period.

    Do not.

    Do not.

    Do not.

    Do not.

    Water+lithium does this.

    And yes, the XL-5 supports lipos. But you have to put it in lipo-mode so that it has low-voltage cut-off.

    Or..well..see the video above.

    I've always got my lipos wet with no issues. My packs in my boat get we constantly. Lithium is very reactive to water but the pack foil does a great job isolating them from the water. That being said it never hurts to be safe. Wrap it in a baloon or silicone you hardpack at the wires and seams.

    Thunder power make's the only water prof lipo i know of,and even then you must buy one specified as water proof.
    And if i bought one that was water proof,I'd still be worried if it got wet.
    I have 19 thunder powers not one it marked water proof,they cost enough as it is.
    Now getting a little water on a lipo case,and soaking in in water are two different things,s.

    Sorry but your video is wrong,when it comes to multi cell lipos and even your phone, the charger it what Tell's it to stop charging.NOT THE BATTERY!!!!
    This video is miss leading and UN true.
    I know first hand,a lipo can,will,and has went up in smoke from over charging.
    That's what balancing chargers are for.
    This guy is going to get some one killed.
    Were not talking single cell lipos here,or cell phones.
    Witch have in fact blown up next to peoples heads from getting wet,it just took a little time for the water to reach the lithe m

    in the vid, how do you know that is the lithium used in lipos. I've dropped a charged lipo in a bucket of water and that never happened. It swelled up slightly but nothing drastic. I try to keep the new lipos as dry as i can though.

    After that they have a series off other videos,just like you tube,they had a gut saying don't worrie about over charging your battery,I think his name was Devlin.
    Oh,I'm sorry if you thought i meant you,what you showed was 100% accurate.
    That's how the cell phone blew up, it got wet but the water took time to seep thru the case and contact the lithium,Is was on the news some time back,but it messed her up pretty bad.
    Sorry again for the miss understanding,i should have been clearer on my post.
    Plus lipos are lithium poly,more like jello,then lithium ion

    Don't confuse pure lithium and lipo batteries. Lipos are much more stable and will not burn when placed in water. They can short however, causing your expensive pack to puff up and be ruined. Any lipo iv seen has been sealed well enough (and indeed has) taken the occasional swim.

    Still, I wouldn't make a habit of it. Either seal the ends with liquid electrical tape or bag your lipos. If they do get wet, allow them to dry completely before giving them any sort of high voltage charge or discharge.

    That's kinda what i was trying to say about rc lipos having more of a jell type composition,than a normal lithium ion battery.
    However I buy no means am any type of battery specialist on these new battery's,but like to learn.
    Thanks for your input,I will continue to try and learn as i go.

    At a guess in the vid i would say it contains sodium also. Old youtube vids show all the delibrate situations that could occur.
    But with much smarter chargers, better built batteries and a better understanding/knowledge of lipo technology by people using them and learning from others, these fires are a more rare of occurance than from a few years ago.
    Go back a few years and see how many batteries burnt up, even without being on a charger or in a loaded situation. I can't remember the last time someone had a lipo go up.

    I thought all Lipo batteries were water proof, cause if air get inside the cell they will start to burn....
    so lipos got to be air tight, therfor waterproof to...

    Are you sure that air causes them to burn? I ripped the foil up on one of my older packs and it did not swell, vent or burn.

    I guess were back to,"water resistant" and"water proof".
    But thank you all, you have all helped in one way or another.

    the lipo cell is 100% water proof but the output tabs are not so they might short out. and over time they will corrode

    That's like saying a balloon it air tight,unless you put a pin hole in it,then it could leak.
    Sure you don't mean water resistant?
    Not a professional opinion,but still.

    So let's all assume lipos are not waterproof, that we should protect them from getting wet, and a balloon will offer some protection.

    Outerwears is also an option to help keep splashes of water off the battery.

    To the OP, your venom battery has the TRX adapter plug which is another site for moisture to get into.

    What makes a quality pack, the only true rating is the cell count and maybe the capacity is close enough to accept.

    Unless i am misunderstanding you,if i am um sorry,But if i buy this reedy pack,it will make be my 22nd pack,only one is 3s,since i only run 2wd class slash short coarse and 3s is just plain to much,I also have a2s 30c venom,the rest are thunder power,they range from 35c to 65c,I can very accurately determine the way my truck will perform by the c rating of my battery packs.
    I'm sure their not all perfect,and change little by little with age.
    But to say cell count is the only accurate way to judge a battery's quality, if by cell count meaning 1s 2s 3s 4s +++,with the exception of volts,Witch still has nothing to do with QUALITY,Is insane,even to someone like me who is in no way into battery specialization.
    I am clearly miss understanding your statement.
    Could you please try putting you opinion of how the # of cells determine quality.=trax de max;5378812]What makes a quality pack, the only true rating is the cell count and maybe the capacity is close enough to accept.[/QUOTE]

    companies use thier own testing for the discharge rates, one companies 20C is another companies 40C and vice versa. Some people look at C ratings as quality.
    There was some airplane dudes that done thier own test with a range of lipos and not one pack was above 36C. The cells don't determine the quality, I just state that this is the only true word on the pack. Which can be checked by anybody to verify that. checking the discharge is a lot more difficult.

    OK thanks,I thought i was missing something,and I get your point,
    Everything but the # of cells, is a companies best guess,and or method of determining that c rate.
    Do you have any opinion on Reedy lipo packs?Just an over priced name,or a known quality product?

    I should have stated that it has been submersed in water, not a splash here and there. It's an RC car, I beat it up.

    My oldest lipo is a hard case Reedy and it has outlasted every other Lipo I own to date. Yes they're about $100, but I can attest to the quality of mine.
    I bought it used in 2009 or so and use it regularly.

    You cant compare the two,its like going from a tricycle to a motor cycle Any of my vxl-3 systems will run 40+pmh,and if you want wheelie on command.I have had trouble ,and even lost against more experienced drivers with one of my castle systems.
    The velenion is one of the best balanced all around water proof systems out there imo.
