There are many things you would know when storing LiPo batteries. While most people just think you need to store your batteries in a cool dry place, there is a lot more that you should know.

So what are some things you should know when storing LiPo batteries?

Here are 8 things you need to know when storing LiPo batteries. 

The best way to gauge what voltage to store your LiPo battery on is to see what voltage the battery is at when you buy it. Manufacturers keep LiPo batteries at storage charge levels, because it may be months before the batteries reach the end user.

  • If you are going to keep your batteries in storage for a while(a while being anything over 4 days), then you want to bring your batteries down to 3.8-3.85 volts per cell. The same goes if your batteries are depleted. If your battery is below 3.7 volts per cell for some reason, you want to bring it back up to 3.85 before storing it.
  • Batteries shouldn’t usually rest at below 3.7 volts per cell. If you land with a pack well below 3.7 volts even after resting for a while, be very vigilant when you charge and make sure to charge very slowly, at less than 1C preferably.
  • Most computerized chargers have a “LiPo Storage” option which will automatically bring your battery to the proper storage charge.
  • Store your batteries in a cool dry place when not in use. 
  • Store LiPos in locations as fireproof as possible. Good places are on the concrete in your garage, or in a metal/glass box away from wood or carpet.
  • Store in temperature-controlled locations – not too hot, and not too cold, and as dry as possible.
  • You can also store the LiPos in a container with a bag of sand on top. If something were to happen, the flames would rip a hole in the bag, the sand would fall on the battery and extinguish the flames.
  • Have a fire extinguisher nearby and easily accessible.

Most of these suggestions actually apply for charging LiPos, but the reason I am listing them here is to be extra cautious, since the times you’ll be storing your LiPos will also be times when you won’t be around them for extended periods.

Now that you know these tips to storing your LiPo batteries, you can store your batteries without any issues and make them last longer. Properly storing your batteries will not only be safer for you, but will make them last longer.

Where to store LiPo batteries?

The electrical aspect of storing LiPo batteries is pretty easy. Physically storing LiPo batteries is a little more complicated.

LiPo batteries contain very reactive chemicals in them(which allows them to produce so much power), so they should not be handled lightly. You want to treat them with as much care as possible.

For starters, you can insulate the leads. This can be as simple as putting a rubber cap or some electrical tape on all of the leads – this includes balance leads and the main power leads.

You should always store your LiPo batteries in a cool dry place and in a LiPo storage bag. Lipo storage bags are made from fire-retardant materials, and will protect you in case your batteries ever catch flames. 

You can buy one of these bags for your batteries by clicking here. These bags are a necessity when storing LiPo batteries in your house.

In case of a fire, the bags won’t completely stifle the flames, but they may give you a little more time to react and dispose of the bag so as not to do damage to your house.

Tips when owning LiPo batteries

There are many things you will want to know when owning LiPo batteries. They do last longer than traditional ones, but there are some added issues you will need to know. 

What are these tips that you need to know when owning a LiPo battery? 

Below are tips for owning LiPo batteries.

  • When you are charging, you’ll always be keeping an eye on the packs.

  • Always remember that heat is the number one enemy of LiPo batteries. The hotter your batteries get, the shorter their lifespan will be. Never charge a battery that is still warm from usage, and never use a battery that is still warm from charging.
  • LiPo batteries do not work well in cold weather. The colder it is, the shorter your run times will be due to the slowing down of the chemical activity within the battery. If it is below 14F (-10C), LiPo usage is not recommended at all. Your battery could cause your R/C vehicle to suddenly fail without warning in these temperatures.

  • A LiPo fire is a chemical fire. You will always want to keep a Class D fire extinguisher nearby your battery charging/discharging and storage area. The battery charging/discharging and storage area should be free from any materials which can catch fire such as wood tables, carpet, or gasoline containers. The ideal surface for charging and storing LiPo batteries is concrete or ceramic.

  • Avoid purchasing used LiPo batteries. While some items are smarter to buy used to save money and help the environment, LiPo batteries are not one of those things.

Now you know most of what you need to know about LiPo batteries. I make no claims that this article teaches you everything there is to know about LiPos, but hopefully, it helps give you some insight into how they work.

LiPo batteries have the potential to overtake NiMH batteries in general use in the next few years, quicker than any battery in history. It is certainly an exciting time for the hobby, and things are changing on a frequent basis.

I love to spend time with my wife and 3 kids. There is no better way to get them off the couch and outside than for us to grab the RC cars or boat and enjoy the sunshine!
