Hey Run Ryders, I'm just dusting off my birds after a 2 year Hiatus... Is it still safe to charge my batteries after sitting two years or should I just get new ones? They have been stored in a garage, although dry and free from the elements it does get rather cold in the NY Winters.. Thank you!

Did you mean to do that? Yeah its called a crash landing its a new trick

Hi, Cold is good, I would charge it, discharge and charge it again. Note the capacity you're putting back in if all is good, go fly.

As long as you use the balance plug you should be safe to charge them. I assume they were stored at around 3.8 volts per cell.?.? What is their voltage after storage - before charging? How old and how used were they when you put them away? Does it get below freezing for extended periods in your garage?

If you have a decent modern charger you will be fine, if the packs have had it the charger will let you know.

I ended up flying my old batts keeping it low and in close to see if they were any good. They still had most of their capacity, but turns out they could not deliver sustained high current anymore. I got maybe 2 minutes before they petered out too much.

Give it a shot. Good luck.

It was quite warm. The old batteries had been sitting for a few years (5 years?) and not kept at storage charge. My charger ( icharge 206) adds up the capacity during charge and discharge, it was within 90% of rated capacity, and seemed OK at home, but the charger was discharging at a much lower rate than the motor does. I have new batts now, they run great and i am doing a better job of taking care of them.

Same happened ti my old packs. But i jeard stiring them at a lower charge would prevent lower capacity issues later. I think its best to just get new packs. I had 3 brand new never used packs for 3-4 years put connectors on and tried them. Worked ok but still no where near as good as my brand new packs.

only you have the power to make no difference!

I charged all my lipos and charged my battery in my DX8i for a whole day and now it just says low battery warning every time I turn it on. The radio charged for 24 hours. I’m assuming the battery is shot so i went to the hobby shop and they were out of them :-/ horizon can’t have it till next week

If you don't want to wait around for Horizon, just google "dx8i battery". I found all kinds of stuff out there, even eBay listings. Ain't no way I'd wait on Horizon for a TX battery.

Just a thought...

Nathan, It's a good thing you haven't been flying for awhile, you're uncle has been dry, not looking for your heli. Do you still live in that cute gray house with the white trim?

That is exactly what I did! I had one shipped quicker from Ebay! I also bought a spare this time.

We bought a house back in 2012 - 2 kids since then, a dog, even a cat now Lots has changed. I started my business back then and its been full speed ahead for the past few years but things are going well now and I'm able to relax a little.. Still working 40-50 hours a week but thats much better than 70 and 80 when I was trying to get everything up and running.
And yes My Uncle has been dry for quite a while, We still laugh about that!! I put a few Helis in My office and I have been looking at them everyday for the past several years. One of my employees finally said are you ever gonna fly those things... I said great idea!!!!

As long as you kept them at a storage charge and balanced they should be fine. I had 4 6s packs I put away for 4 years and have been flying them again for over a year again. Charge them up watch the cells and see how they perform. I would charge at 1c for first charge then let it rip and see what happens.
