Storing your lipos

I know for some of you lucky ones that live in the south there is no off season. For those of us that live up north however, the flying season is winding down. I might get out to fly a couple more times before I head to the shop to build next years planes. Anyway, if you set your lipos aside and don't use them for awhile it's recommended to store them at 3.82 volts per cell. This keeps them from loosing their ability to deliver proper voltage under load. I have a charger that will automatically put them in a storage state but you can do this yourself with any charger and a volt meter.

After you do the "storage charge", put the batteries in an airtight container in the bottom of your refrigerator. Or so I've been told.....

Well, that's interesting. I haven't heard that one before. I keep mine in the basement which remains fairly cool in the winter. I'll probably forgo the refrigerator treatment.

Sure, discharge them to storage voltage if you want. I wouldnt bother since the packs are cheap and peak current draw in on the order of only a couple C's. Packs are cheap as well. Replacing is cheap. If you sleep better at night then do it. I would recommend cycling the packs to determine their true capacity though. Over time, their capacity could decrease. This is good practice.

There's a few guys here in AZ that has "battery fridges" in their garage. I've been told their most easily found at the END of the college school year.

During the summer, they store their "big" expensive packs in ziplock storage containers with a few packs of desiccant in those little fridges with the packs at storage charge.

I'm with Paul, though. The little DLG sized lipo packs are relatively cheap, and I'd rather know for certain the pack is good. Cycling, at least, but I'd replace them for $3 a piece. Cheap insurance, so to speak.

Well, I suppose you're right about the cheap part, at least for these DLG receiver packs. Might better just buy new. I'm going through the process of putting some 8S 5000 packs into a storage state and during my idle time I posted this thread. My RX packs are very new. I'm going to put them at storage charge too. If I had flown them all season, I'd be inclined to replace them.

I store my batteries in the winter...3.8ish volts and the cool of the basement is just fine. As long as the batteries are not freezing or frying you're in pretty good shape...60-70F steady temp is just fine.

I have some packs that are 3-4 years old and still test to 90% or more of their "when new" capacity.


The fridge trick is smart if you don't have temp controlled storage available, like in a garage, however if your unheated garage is in Minnesota where it can be below zero for a week, your fridge might just turn into a freezer
