lipo storage temperature
Hi guys,
I recently built a charging/storage cabinet for all my batteries. I have lipo, lion, nimh and nicd batteries for my different cars ect. My question is that id like to keep this cabinet in my garage however, summertime temps in the garage can be up to 105°F for about three months out of the year. Is this ok or do I need to move the cabinet inside? Id like to keep it in the garage if possible. I have a mini fridge in the garage but im worried it may freeze them if left in there as its not the greatest temp wise. Ice cold beer and water is cool but im thinking it may be too cold for the batteries. Thanks for any input and suggestions.

Need to Store Batteries? Here’s how to do it safely:
1) Keep batteries in original packaging when possible.
2) Do not store new and used batteries together.
3) If a battery feels warm, it should be discarded.

Thanks for the reply guys. I have a steel cabinet lined with sheetrock that I use to charge and store batteries in. I purchased a couple of lipo bags and keep them in an ammo box with seal removed in the cabinet. All charging and storage is done in the cabinet and in the hot months ive been keeping the cabinet in the laundry room. The weather is cooling off here so im going to move the cabinet back to the garage. There is no threat of freezing where I live so I should be good.

Storing them in that garage with 105°F ambient air temp is fine.
We had 115°F for a few days in a row last month, and the actual temp in the garage was less then 100°F. If you are interested, place a thermometer in the cabinet with the door closed the next time you think it is too hot outside.
Warning: Assuming the laundry room is inside the house, you would never store or charge the batteries in the house. Even in a cabinet.
There are just too many things that can make a LiPo mad.
Once a pack starts burning, while you may not catch the house on fire, the toxic gases that are being generated can cause you and your family serious harm.
The things that do the most harm to LiPo is over-discharge, over-charge and crash damage.
If you can make it a practice to store them around 50% charge, only charge to 4.15v / cell, only discharge to 3.8v / cell and never draw more current out than they can deliver (exceed the true C-rating) they will last for a long, long time.
If you rely on the Low Voltage Cutoff on the ESC, they will have a short life - so don't do that.
I'd really like to know more about the reasoning behind these 3 points.
Is there a special battery chemistry that these relate too? I've never heard of any of these being related to Lithium packs.
