3s Lipo Fully Charged Voltage: All You Must Know

Last updated: May 17, 2023
3s Lipo Fully Charged Voltage

Li-po batteries, or lithium-ion polymer batteries, are the most commonly used for electric vehicles (EVs). But what is the best figure for 3s Lipo fully charged voltage?

This rechargeable battery can achieve a high energy density like no other, which is why they are popular in multiple vehicles, notably employed as RC car batteries. 

In fact, 3S is better than 1S or 2S rechargeable battery types, appealing users to make a purchase research in seconds.

You can have them charged in myriads of ways. Manufacturers recommend charging them depending on each battery’s particular attributes and intended usage. 

Have a quick look at the in-depth analysis below to enrich your knowledge about 3S Lipo.

What Is A 3s Lipo Battery?

What Is A 3s Lipo Battery

A 3S Lipo battery includes 3 rechargeable lithium polymer cells (Lipo cell) arranged in series. Its other name is 3S1P configuration (or rechargeable battery types). The 3S Lipo voltage range is from 11.1 to a maximum voltage of 12.6 with a cut-off voltage of roughly 9. 

In particular, every single battery’s cutoff voltage can fluctuate from 2.7 to 3.0, with the charging voltage from 3.7 and the maximum voltage being 4.2 volts. Most of them fit the discharge current in the 50-100C range. 

A 3S Lipo is a lithium-ion battery used widely in RC models and other applications such as drones, planes, and trucks. In some cases, they will provide the temporary electrical energy for acceleration, liftoff, and some maneuvers.

Unlike a lead-acid battery, a 3S Lipo does not lose its capacity due to increased discharge cycles.

3S Lipo Fully Charged Voltage – How Many Are Good?

Get one thing clear: the excellent full charge voltages for 3s Lipo need to suit the sum of volts per cell. We mean that the 3S acquires 11.1 volts, equal to the sum of 3 individual cells (a battery voltage of 3.7 for each).

Overcharging is nothing but a quick way to shorten the 3S’s life expectancy. The required time may be available in the battery manual.

3S are larger batteries compared to 1S batteries and 2S rechargeable battery types. Regarding power output, electrical energy, and battery capacity, the 11.1 volts of 3S also beat the latter. Cars or electrical devices using 3S Lipo batteries always perform better. Still, the 3S Lipo is never a lightweight type.

The Best Methods To Preserve Your Lithium-Based Batteries

Stay tuned to broaden your knowledge about 3s lipo battery preservation, including why they’re so challenging and what you can do to keep them from going bad. Be wise to follow the battery manual in such cases.

Stick To The Battery Manual

After buying a rechargeable lithium-polymer battery, the top priority is reading the battery manual thoroughly. Recharge as soon as possible once you spot the Lipo 3s battery low voltage to ensure its proper operation.

Manufacturers know more about your Lipo than anyone out there. What they emphasized in the products is thus vital to notice, notably how to effectively prolong the entire battery life.

Otherwise, you may get into trouble due to incorrect use; even worse, you will ruin your batteries entirely.

Track You Batteries During Charge

Keeping an eye on your batteries before and during charge is a must. Rechargeable batteries tend to get down at a high temperature. It may lead to partial vaporization inside the polymer electrolyte. 

In the worst scenarios, the cases can rupture, and the flammable electrolyte is prone to catch fire and explode. Beyond that, the near-explosion or damaged batteries often get puffed or release smoke.  

Things can be controlled under supervision. It makes sense to store the batteries in fireproof bags or containers. Be careful with any weird signals that pop up. 

Lastly, always use the correct battery connectors during charge.

Remove Any Bad Lipo Battery

Regarding any bad Lipo battery, you’d better remove them out of battery connectors at once. As such, you will avoid dangerous, even fatal risks. 

It’s non-debatable that the puffed batteries are satisfactory to use. Still, some out-of-date batteries can go with smoke or unpleasant smoky smells, implying their potential dangers. 

Keep in mind to adhere to disposal protocols for damaged batteries. You couldn’t treat them like regular appliances or items due to their distinct chemical components.

Don’t Store Fully-Charged Batteries

Avoid storing your fully-charged ones. This way will shorten the battery life rapidly. Alternatively, discharge the full charge to the storage voltage if you wish to tuck them away. 

What’s more, keeping your batteries at room temperature always works wonders. High or low temperature always creates adverse effects on the batteries. 

Cold weather may prolong the items’ lifespan, yet they develop condensation inside them, which is risky. Indeed, a cold battery is never a good choice for your vehicles. 

Also, the hotter the condition is, the shorter your batteries can last. 

Recommended Charging Frequency For Your 3S Lithium-Based Batteries

With a Lipo charger, it often takes roughly 2-3 days for each charge for your 3S Lipo battery. The total time may vary based on the battery type and brands. Hence, reading the battery manual is handy to boost the battery’s life expectancy and performance.

Don’t leave them fully charged for long. Once fully charged, your items should be used at once. Overcharging will cause degradation and increase the heat inside. 

Maintain the proper storage voltage if you don’t use the fully charged ones in the next day or two or for storing. 

You might as well discharge them to a storage battery voltage (roughly 3.6-3.8 volts per cell). Lastly, ensure you use the correct balance charge for your entire battery.

Wrapping Up

If you’re a serious racer or even just a track day enthusiast, it makes sense to get to know the ins and outs of your car battery. After all, it directly impacts your car’s performance and the distances you can travel. 

To help you make the most of your car’s battery, this guide on 3S lipo fully charged voltage offers some core information about identifying what your battery is and how to keep it in good working order. 

Hopefully, this post can help you untie the knot about this battery type.
