LIPO question

[Bukwylde]

I just purchased some brandy new 3s lipos, but I won't be using them for a couple of months. What should I do to make sure they don't go bad? Thanks in advance.

i read somewhere to charge them to 50 or 60% to store for weeks. I know it says not to store them fully charged

Yeah 50-60% is where you want to be at for extended storage. That should put you about 3.85v/cell. you don't want any cell to drop below 3.2v. Lipos self-discharge less than nimh, so you should be ok for a month I would guess. If you want to extend it longer than that I would place them in ziplock bags with the air pressed out and place them in the fridge, next to the beer.

if you just picked them up and never used them, more than likely they are at 75% charge which is perfect for storage. leave them in a dark, dry, cool place and you will be just fine

Thanks for the great adviceev eryone! These are my first lipos. I bought them because they were on sale but my trucks not even close to ready. I have all the parts just not the time! So I guess it will be about 2 months before I use em. Which brings me to my final question. After a month should I cycle them or just check the voltage?

You'll be fine just leaving them alone. Many lipos sit in stores, warehouses and hobby shops for several months...

Make sure they are around 3.8 per cell and you're good to go..

Excellente! Thanks all!

You don't want to leave them in below freezing temps. Or above approx 130*. If your going to not use them for a LONG time, I recommend fully charging them. All new packs I've gotten where near full charge. Can hurt "punch" very slightly (probably never noticed in a crawler), but not nearly as much as letting them over- discharge which can be unsafe!

Where did you get those fully-charged batteries from? Mfgs should be shipping out batteries anywhere from 40-60%. Storing batteries at 100% just puts unnecessary stress/pressure within the cells. There is a ton of literature out there for reference. Batteryuniversity.com is great and they update regularly.
