Batteries are an important part of any device. However, batteries should be stored efficiently and safely to maintain their shelf life. LiPo batteries are no different. LiPo batteries, also called drone batteries, are quite expensive and can easily be damaged when not stored properly. Proper LiPo battery storage is crucial for extended battery life and makes it safer for everyone around us.
So, how should LiPo batteries be stored? Whether you're just at home or you're preparing for your next event or trip that requires a lengthy journey, LiPo battery storage is important. We've compiled extensive research on your behalf and created the ultimate guide to everything you need to know about LiPo battery storage.
What is a LiPo Battery?
LiPo is an abbreviation for lithium polymer battery or lithium-ion polymer battery. A LiPo battery is a type of rechargeable battery that utilizes a soft polymer casting which allows the lithium-ion inside to rest in a soft-like external "pouch." LiPo batteries are preferred because they're more flexible and lighter than other lithium-ion battery types due to their soft shells. Their flexibility makes them convenient for electronic devices such as drones, phones, remote control (RC) cars, and other radio-controlled devices.
LiPo batteries are among the safest forms of RC batteries, however they can be extremely dangerous if they're improperly stored, handled, charged, maintained, or discharged. You won't necessarily see any expiry dates on LiPo batteries, but you'll slowly notice a drop in performance as time passes by. Proper LiPo battery storage is also crucial for your battery life to last longer.
Storage Voltage for LiPo Battery
So, what's the best storage voltage for LiPo batteries? When you purchase a new LiPo battery, it comes partially charged. The partial charge accompanying a new LiPo battery is the LiPo storage voltage. LiPo battery storage voltage is kept at approximately 3.8 volts. It's advisable to discharge or charge your LiPo battery to about 3.6 to 3.8 volts before storing it because LiPo rechargeable batteries are most stable at this voltage.
LiPo batteries can be temperamental to the extent of catching fire if not handled and stored properly - hence the importance of LiPo battery storage. Here's what to do if you want to store your lithium polymer battery:
1. Check Your Battery's Voltage to Determine if You Need to Discharge or Charge It to the Right Voltage
Given that the most stable voltage for a LiPo battery storage is approximately 3.8 volts for each cell, you'll need to set your LiPo battery at that voltage before storing it. Most LiPo chargers are accompanied by a volt reader, making it easier to check the battery's voltage. You can check your LiPo battery's voltage in two ways:
- Insert the balance plug into the port on the charging unit and wait for your battery charge reading. (A balance plug is a plug connected to different colorful wires that come out of the battery)
- If your LiPo battery does not come with a volt reader, you can simply use a basic voltmeter. Connect your voltmeter's positive (+ve) wire to one end of your balance plug and the negative (-ve) wire to the opposite end. Hold both ends for some seconds until your voltmeter produces a reading.
2. Set LiPo Battery Charging Unit to the Appropriate Storage Setting if it Has a Default Setting
After checking your battery's charge, the next step is to adjust the volt to the storage setting. Some LiPo chargers are built to have a default LiPo storage setting. These chargers automatically charge or discharge your LiPo battery to the appropriate voltage, making the storage preparation much easier.
- To adjust your battery's charge, set your charger to the automatic LiPo storage setting and plug your battery in until it reaches the storage volt setting.
- The LiPo battery charge or discharge process is slow, so expect it to take about an hour.
- Bear in mind that different battery chargers operate differently in the programming process.
How to Charge LiPo Battery for Storage
If your LiPo battery charger does not come with a storage setting, you'll have to either charge or discharge it manually to the LiPo storage voltage. If your LiPo battery reads below 3.8 volts, you'll charge your battery to the storage charge.
First, you'll set your charger to 3.8 volts. You'll then plug the battery in and wait for the battery to reach the set voltage. Once the battery reaches the set time, it will automatically stop.
How to Discharge Your LiPo Battery for Storage
LiPo batteries tend to discharge quickly, which increases their capacity to serve continuously without damaging the battery. The measure of how your battery can be discharged safely without destroying the battery is called the C rating. The LiPo battery's discharge rate is also called a LiPo C rating.
If your LiPo battery reads above 3.8 volts, you'll need to discharge to the right storage voltage. To discharge your battery, you'll set a discharge setting to bring down the battery's charge to 3.8 volts.
How to Store Your LiPo Battery
If you store your LiPo battery properly, you avoid damages to your battery and increase its lifespan. So, how do you ensure that your LiPo battery is stored properly? Here are tips on how to store your LiPo battery:
LiPo Battery Storage Tips for Home
When it comes to LiPo battery storage at home, the main focus is your family's safety and, of course, your valuable items. The biggest risk of a LiPo battery at home is that it could cause a fire when not handled or stored appropriately. Here are tips for storing your LiPo battery at home:
- Check your battery charge level every month. If you're storing your LiPo battery long term, the battery charge might reduce over time. Checking the battery will ensure your battery stays at the appropriate voltage.
- Place your battery on a safe, non-flammable surface when charging or discharging your LiPo battery.
- Store your LiPo battery in a fireproof bag or charging safe. The best LiPo battery storage containers are designed in a way that they can contain flames and prevent toxic flames from spreading.
- Store your LiPo battery in a cool and well-ventilated place. It's advisable to store your battery at room temperature and avoid cold or hot areas.
LiPo Battery Storage Tips for Travel
Are you planning a long trip or event? LiPo battery storage when traveling can be tricky because it needs proper planning prior, regardless of your travel method. Here are LiPo battery storage tips for travel, depending on each method of travel.
LiPo Battery Storage Tips for Vehicle Travel
- Keep your LiPo battery within sight and safe in a portable LiPo battery storage container.
- Don't place your LiPo battery in the trunk, and don't stack your RC gear on top of your battery.
LiPo Battery Storage Tips for Plane Travel
- Check with your airline's regulations and guidelines to see what's required of you when traveling with your LiPo battery.
- Carry your LiPo batteries onto the plane. Don't place your LiPo batteries in checked luggage.
- Cooperate with the screening agent when your battery bag is checked to ensure that you comply with all the required guidelines.
LiPo Battery Storage Accessories
Whether you're staying at home, planning to travel abroad, or planning for a trip, proper LiPo battery storage is crucial, and that's where LiPo accessories come in. Here's a list of the necessary LiPo battery accessories that can help you make your storage a lot easier and safer:
