LiPo Battery Cell Voltage-Voltage and Caring

Jan 14, 2020   Pageview:222

In the era of technology and advancement, everything that is been used related to our daily life runs either on electricity or by batteries i.e. a cell. The electronic devices and appliances that are being manufactured today are produced to offer maximum leisure for its users. That's why the industry of batteries is blooming. Every other day a new type of battery is introducing in the market carrying much-advanced components and elements.

One of the recent developments in the power world is LiPo batteries or Lithium Polymer batteries. These batteries are popularly used as the means for powering the electric models. Lithium polymer batteries offer reliable, renewable, convenient and comparatively inexpensive power source. Let us discuss more to gather information about lithium polymer batteries.

How many volts are in a LiPo cell?

Before digging about the volts of the LiPo cell, let us understand the utility of LiPo batteries. Well, lithium polymer batteries are used for many consumer electronic devices. These batteries are also getting popularity in the industry of radio control as well. LiPo batteries are now one of the most famous choices for those people who are looking for batteries that offer high power and long run time. Other than providing high power and good run time these batteries have an array of benefits to offer. 

Talking about the volts or cell count of a LiPo battery, it has a nominal value of 3.7V.  In the early years of LiPo batteries, the battery pack was described as "2S2P". The term used to mean that there were four cells in the battery i.e. two cells wired in the series and the remaining two more wired into the first two batteries in parallel. In the parallel form, the capacities of the cells get add together. This terminology or abbreviation is not in use today. The modern and advanced technology has allowed the batteries to have an individual cell that is able to hold much more energy than they could hold in the past. 

The voltage of a battery pack crucially helps in determining how fast your vehicle is going to go. Voltage is directly proportional to the RPM of the electric motor. Voltage also influences the RPM.

What is the lowest voltage for a LiPo battery?

Well, many users come up with this question. So, one thing is certain that you are not alone who is curious about the lowest voltage of a LiPo battery or how low can you go? You have already gone through several forums related to the battery world, but got overwhelmed with so many questions. Well, no more trouble as below is the simplest and short answer to your question. 

Well, the minimum is generally listed as "3.0" v. 

To bear in mind that, discharging your LiPo cell below 3.00 surely damage the cell. Don't ever discharge the cell so low unless it is required in special cases. In fact, the lowest that anyone would recommend is 3.00v per cell. 

How do you care for LiPo battery voltage?

Following are the certain things you can do to care for your LiPo battery voltage -

Before charging your LiPo battery, keep the following things in the mind:

  • The first tip is to read the instruction manual, whether you like it or not. This is the first step to take care of your battery. 

  • Always inspect the voltage of your batteries before every charge session to make sure that they are at/above the minimum safe starting voltage. And if their starting voltage is bellow than recommended levels, then the batteries have been over-discharged or have encountered a failure and you should not charge them. 

While charging LiPo batteries, keep the following things in the mind:

  • Only buy and use a charge specially designed for a LiPo battery. Don't ever use the one designed for other battery technology like NIMH. And if you have a charger supporting different battery types, make sure to choose the LiPo mode on the charger before charging your batteries. 

  • You should always charge your batteries in a wide and open area and away from liquids, surfaces and flammable materials. 

  • Never ever charge your cells inside of the drone. 

  • Never ever charge your cells below freezing - (0°C, 32°F)

  • Never even charge your cells that are extremely hot when you touch them (above 100° F).

  • You should never set the charger to charge your batteries at a rate >1C. 

  • Don't ever overcharge batteries over their maximum voltage (rated). 

While discharging LiPo batteries, keep the following things in the mind:

  • Don't discharge cells at amperage rates, which are higher than rated on the label. 

  • Don't discharge your battery to a level below three voltage per cell under load. And for most drone batteries, the suggested cut off voltage is 3.5 voltage per cell. 

Following are some general tips to take care of your LiPo battery -

  • The voltage of your battery should be 3.6 to 3.9 voltage per cell. 

  • Never ever left batteries unattended while charging. 

  • Make sure that LiPo charger settings are right for the battery pack for charging - both current and voltage settings. 

That's all about what you can do to take care of your LiPo battery voltage. All these things directly or indirectly help in taking care of lithium polymer battery voltage. As you can see that the longevity of your battery life is in your own hands.
