    my charging setup

    now that im getting lipos my dad doesn't want them in the house so i set up a place out in the shop.

    i used an old tool box to put the batteries in while they charge and modified it so that the cords can get in. its on an old cast iron wood burner.

    this is inside the toolbox.

    and a video just for fun. i know it cant be good for the tires but i also do it on concrete anyways.

    Nope. Never.
    Even if they fully discharge themselves they won't catch fire.
    Whatever it is I just typed... could be wrong.

    The other day I went to do a 5 cell run in my merv and accidentally used my parallel connector instead of my series connector ! After a few minutes when I carried it outside it was getting warm. My 3 cell had dropped to 9.8 volts and the 2 cell voltage raised up to 9.8! I disconnected the connector and ran the 2 cell to quickly lower the voltage and so far no problems! Batteries spent the night in the battery bag. Batteries balance out fine and take a full charge.

    yes. Safety first.
    Most fires I see from Lipos (on the net) are from aggressive charging and or puncturing them.
    Ive seen 1 let out the smoke gnomes but that was from over amping the crap out of them while charging. Trying to get that edge in a Spec Slash class.

    Far as your box goes, Id install some kind of gasket or insulation where the raw metal edges are just as a safety precaution. Dont want to arc the wires should they happen to get cut on a sharp edge.

    Be sure to balance charge EVERY time... it only takes a few seconds if you have a good charger.

    Tires are the least of your worries with those Cyclones. Your Diffs are working overtime when you do that.

    Nice charging setup BTW. Im in the process of an upgrade. I have a Triton2EQ right now. Looking for more.

    Why do lipos have to be stored at a certain voltage? Its 3.85v per cell. Right?

    It does not have to be 3.85v/cell... anywhere between 3.5 and 3.9 volts works. It keeps the cells from being overstressed and overdischarged.

    If you store them fully charge you will lose capacity over time.
    If you store them too low and don't check on them the voltage could drop too far ruining the pack
    3.85 is a good voltage especially when you don't plan on driving for a while
