    Traxxas Lipos

    Do you need a LIPO bag for the traxxas batteries or will the built in balance of it make it not necessary

    I personally always charge my lipos in something. I use a small charcoal grill. A bag works well also. It's a good safety measure. Some people don't use them. It's just all a preference.

    It's really, really hard to bag charge Traxxas lipos on the Traxxas charger. If you do get the lead out of the bag you've not really prevented a fire hazard, so it's best if you can just put the whole assembly (battery and charger) someplace not flammable. If you're not using a Traxxas charger and instead using an adapter, you can make any length of lead needed to bag charge securely.

    Also, don't charge in the bathroom or near water sources. You don't use water on a LiPo even if it does catch on fire. If for some reason you do have a failure (very unlikely, but it can happen) just smother the battery in sand or dirt. No water. Water+Lithium= Boom = flames everywhere.

    oh yeah I already knew that lol I used to work with military radios and our lithium batteries would come in a 55 gallon barrel full of sand.

    Rechargeable Lithium Ion batteries, unlike primary Lithium cells, actually contain none to very little metallic Lithium so using Water in conjunction with a Lithium Ion battery thermal run-away will not cause any worsening of an already existing fire and water can help contain the release of Hydrogen fluoride gas into the air as well as cool the battery down reducing/eliminating the flammable gas release.

    If you're able to achieve immersion water is acceptable. If you're just sprinkling water on it though? You're just adding fuel. LiPo batteries contain a small amount (avg 3 grams?) of Lithium, albeit not enough to sustain a fire when exposed to water but enough to violently boost an existing fire during the reaction.

    The pack will flare for a short period, dirt/sand is a much more effective method of containing the flare until the pack settles.
