When it comes to powering drones, RC cars, airplanes, and other high-performance electronics, 2S LiPo batteries are a top choice. Their lightweight design and high energy density make them incredibly efficient, but they also require proper care, especially when it comes to storage.

Improper storage of your 2S LiPo battery can lead to decreased performance, reduced lifespan, or even serious safety hazards like swelling or fire. In this blog, we’ll walk you through the do’s and don’ts of LiPo battery storage, so you can protect your investment and ensure peak performance for the long haul.

What Is a 2S LiPo Battery?

Before diving into storage practices, let’s quickly cover the basics.

A 2S LiPo battery contains two lithium polymer cells connected in series. Each cell typically has a nominal voltage of 3.7V, so a 2S battery provides a total of 7.4V. These batteries are known for their ability to deliver high current and are commonly used in hobby electronics.

However, their sensitive chemistry means they must be handled with care, especially when not in use.

DO: Store at the Proper Voltage

The most important rule for storing a 2S LiPo battery is to store it at the correct voltage.

Ideal Storage Voltage:

• 3.7V to 3.85V per cell
• For a 2S battery, that’s 7.4V to 7.7V total

Storing a battery fully charged (8.4V) or fully discharged (<6.0V) can damage the cells, reduce capacity, and shorten the battery’s life.

✔ Tip:

Most LiPo chargers have a “storage mode” or “storage charge” feature. Use it to bring the battery to the optimal voltage before putting it away for a few days or longer.

DON’T: Store Fully Charged or Fully Depleted Batteries

Storing your 2S LiPo battery fully charged or discharged is a common mistake that can lead to:

• Cell degradation
• Puffing or swelling
• Decreased capacity
• Risk of fire or thermal runaway

NEVER:

• Leave the battery fully charged after use
• Store it below 3.6V per cell for extended periods
  

Even if you’re planning to use the battery “soon,” it’s best to bring it to storage voltage unless you’re using it within 24–48 hours.

DO: Use a Fireproof Storage Solution

Safety first! LiPo batteries can become volatile if they are damaged or stored improperly. It’s essential to store them in fireproof containers.

Recommended Storage Options:

• LiPo-safe battery bags
• Metal ammo boxes (with vent holes)
• Fireproof containers (ceramic or steel)

Place the container in a cool, dry area—away from flammable materials—and ideally on a non-flammable surface like tile or concrete.

DON’T: Store in Hot or Humid Conditions

Heat and humidity are enemies of battery health. Exposure to extreme conditions can:

• Increase internal resistance
• Causes swelling or leakage
• Lead to reduced performance and a shorter lifespan

Avoid:

• Attics or garages without climate control
• Cars are parked in the sun
• Near heaters, radiators, or direct sunlight

DO: Store in a Cool, Dry Location

Temperature plays a crucial role in the health of your 2S LiPo battery.

Ideal Storage Conditions:

• Temperature: 10°C to 25°C (50°F to 77°F)
• Humidity: Low (use desiccants or silica gel if needed)

A temperature-controlled room or basement is ideal. If you live in a humid climate, consider using a sealed plastic container with moisture-absorbing packets.

DON’T: Stack or Crush Batteries

Pressure or physical damage can cause internal short circuits, which may lead to fire or explosion.

Avoid:

• Stacking multiple batteries directly on top of each other
• Putting heavy items on top of stored batteries
• Tossing them loosely in drawers or toolboxes

Use dividers, padded containers, or dedicated storage trays to keep them secure and separated.

DO: Check Battery Health Periodically

Even while in storage, a 2S LiPo battery should be checked regularly—ideally once a month.

What to Check:

• Voltage: Make sure it’s still between 7.4V–7.7V
• Physical condition: Look for swelling, puffing, or leakage
• Connector health: Inspect for corrosion or loose wires

If the voltage drops below 3.6V per cell during storage, recharge back to storage voltage using your balance charger.

DON’T: Ignore Swollen Batteries

If your 2S LiPo battery shows signs of swelling or puffing, it’s no longer safe to use or store.

Swollen batteries are unstable and dangerous, even if they still seem to function. Continued use or improper storage could lead to thermal runaway and fire.

What to Do:

• Isolate the battery immediately
• Place it in a fireproof container
• Follow local regulations for safe battery disposal

Never attempt to puncture, compress, or dispose of a swollen LiPo in household waste.

DO: Label Batteries With Storage Dates

If you have multiple LiPo batteries, it’s easy to forget when each one was last used or checked. Use labels or tape to mark:

• Date of last use
• Storage voltage
• Number of charge cycles

This helps you keep track and rotate usage to extend battery life across your collection.

DON’T: Store With Devices Plugged In

Leaving your LiPo battery connected to an RC vehicle, drone, or charger—even when powered off—can slowly drain the cells.

Tip:

• Always unplug your battery after use or charging.
• Use dust caps to cover exposed connectors for safety.

A drained battery left plugged in too long can dip below the safe voltage threshold, leading to irreversible damage.

Final Thoughts

The 2S LiPo battery is a powerhouse of performance when handled correctly, but improper storage can turn it into a liability. By following these do’s and don’ts, you’ll protect both your battery and your gear while ensuring the longest possible lifespan and best performance.

Here’s a quick recap:

Do:

• Store at 3.7V–3.85V per cell
• Use fireproof containers
• Keep in a cool, dry place
• Check voltage and condition monthly
• Label your batteries

Don’t:

• Store fully charged or empty
• Keep in hot or humid areas
• Stack or crush batteries
• Ignore swelling or damage
• Leave connected to devices

With the right storage habits, your 2S LiPo battery will stay safe, strong, and ready for action whenever you need it.

It is known that air conditioning technology needs lots of energy. Cooling buildings account for 10% of our global electricity consumption. That’s bad news for global warming. Cooling the indoors contributes to the heat in the outdoors. This vicious cycle has contributed to the precipice of doom we are heading towards. 

There are, however, energy-efficient solutions, both traditional and modern. In much of the world, energy-guzzling technology is powered by fossil fuels. These emit lots of greenhouse gases, which make the atmosphere hotter. 

Better Air Conditioning Technologies

Nowadays, ACs have refrigerants running through their coils to absorb heat from the warm air. Some of them are literal greenhouse gases. You don’t want those leaking out of your unit. On top of that, air conditioners cool indoor spaces by pushing out the heat that refrigerants absorb. That means they make the immediate surroundings hotter, too. 

There is no technological reason for ACs to use as much energy as many commercial models do now. In humid countries like India, Singapore, or parts of the US, about a third of the energy is used for managing humidity. While some modern models have a so-called dry mode to target humidity, air conditioners are still pretty bad at measuring how much moisture is in the air and determining how much needs to be expelled to maintain a comfortable temperature. 

As a result, many people simply blast their ACs to over-cool the room and get the humidity down to the desired level. If ACs had better controls and sensing capabilities, they would be able to sense both the temperature and the humidity. By doing so, they would be able to optimize the performance of an air conditioner.

Pro-Tip: If you want to save up on electricity (specifically air conditioning) integrating energy-saving strategies in your Smart Home Automation system is a good idea. Xfinity offers a great smart home system with a feature that turns your electrical appliances off timely when they are not in use. They also have a more intelligent thermostat that tends to control the air conditioning more economically. Unlocking the features that save energy can be a challenge you can resolve by calling support on Xfinity phone number. 

While the more efficient air conditioners are costlier upfront, you will save much more energy over the ten-year lifetime of that air conditioner. And therefore, the total cost of ownership is about half of the standard products. But that’s where the challenge lies. Either consumers don’t have the financial ability to spend that money upfront, or they are just not aware of it.

Construction of Cooler Buildings

Traditional architecture is the main solution to this problem. We see the manifestation of this in some modern buildings such as Qatar University, which uses wind towers to keep its buildings cool. Other Middle Eastern countries like Iran have been using this technology for centuries. These wind catchers are designed to trap fresh air and direct it indoors. 

Additionally, noticing the sun’s orientation throughout the day and accommodating that in your façade design is imperative. Wind direction is a key parameter to design a good cross-ventilated building. Other solutions include shading devices and insulation. They keep the façade to a lower temperature and prevent heat from traveling through your roof.

You may also have noticed that houses in tropical zones are often white. Some countries like India paint roofs with lime-based whitewash, which absorbs less heat. This can reduce indoor temperatures by 2°C to 5°C.

How Different City Governments are Combating Urban Heat Island Effect?

The urban heat island effect is when urban areas like these get warmer than their surroundings because all this concrete absorbs and retains heat. There is also lots of waste heat from human activities like transport and, of course, air conditioning. Creating more spaces with shady trees and other plants lessens this effect.

The Colombian city of Medellin reduced average temperatures by 2°C only three years after planting green corridors. The interconnected network of greenery spans dozens of waterways and busy, polluted streets. 

Minimizing heat expelled by cars also makes a difference. In Spain, Barcelona’s superblocks prioritize pedestrians and cyclists. But scale matters. The city’s Institute for Global Health estimates that 117 heat-related deaths could be avoided every year if hundreds more blocks were introduced.

Singapore is using a large-scale underground air conditioner, touted as the largest in the world, that cools residential buildings, banks, malls, and this iconic hotel. The technology is called district cooling, and it can save up to 50% on energy and emissions. That’s because having one big plant cooling an entire district makes it super-efficient. The water is chilled 25 meters below the ground before it is piped across different buildings.

Cities like Toronto, Paris, and Hong Kong are shifting rapidly to the model where they cool dozens of buildings with one central cooling system. In some cases, district cooling makes use of networks that already exist. Most of the system in Paris runs through the city’s sewage network. 

District cooling is better suited for new constructions. For example, Gujarat International Finance Tec-City—also known as GIFT City. 

Climate Action: A Responsibility, Not a Choice!

All of this may sound utopian, but like all other solutions, it requires lots of upfront capital, know-how, and of course, awareness. Still, experts say this type of investment is urgently needed—whether on a city-wide or neighborhood-scale or broader technological innovation. The good news is cooling doesn’t always have to look like this. But if we don’t move in a more sustainable direction fast enough, we risk staying trapped in a solution that is part of the problem.
