LiPo Discharge Rate – A Complete Discussion

Introduction

LiPo batteries are vastly used in regular electrical works nowadays. They are popular for their improved functionalities. But it’s also true that they discharge at their rate.

So, what’s the LiPo discharge rate, and how does it affect everything?

Usually, this discharge rate means the nominal range of load provided by the battery. This delivery rate can vary on different LiPo batteries. Generally, it ranges from 3.7-3.9 volts per unit of capacitance. Having a discharge rate of more than 30% of the total capacity is considered ideal.

This may still confuse you about the discharge rates of the LiPo battery. But we’re here to help so that you can get going. In this article, you’ll get to know everything from the very basics. Please have a read.

A Broader Look Into Capacity and Discharge in A Battery

The capacity of a battery simply means the maximum storage limit in the battery. The battery can’t hold more power than its capacity. So, if the capacity is more, the battery can be used for longer on a single charge. However, it produces heat as well.

When the battery is in use, power discharges from its total capacity. This discharging action is measured by a quantity called Ampere (A). If a battery discharges 1 Amp every hour, then it’s called 1 mAh capacitance. In other words, this is the discharge rate of that battery.

Sometimes, this discharge rate is expressed as a “C” rating. The increased number of C ratings means that the battery can be discharged faster if needed. A high discharge rate or high C-rated batteries can be used for better power delivery.

There are also terms like 3S and 4S batteries. They usually denote the number of battery cells in a series connection.

How to Calculate The Discharge Rate

LiPo batteries are rated 20C, 30C, etc. Now if a 5000 mAh battery is rated 30C, the discharge rate will be as below.

5000 mAh = 5 Ah

So, for 30C rated battery, discharge rate = 5A x 30 = 150A

So, this is the way you can calculate the discharge rate of a LiPo battery. Hope this won’t be difficult for you.

There are a few ways to degenerate more power from the battery. However, that’s not recommended. Because that can cause the battery to work more than usual which may result in a battery explosion.

Things to Consider When Buying A Battery

A high C-rated battery circulates more power and encounters less voltage drop. That’s why they deliver better performance.

While buying batteries, you should look for better-performing batteries. But you should keep in mind the device requirements also where the battery will be used. Because connecting an overpowered or underpowered battery to your device won’t do you any good. So, choose the battery capacity and parameters that suit your device well.

Also, make sure to charge your LiPo battery well when you use it. Use good quality chargers for recharging the battery.

FAQs

Is it important to know LiPo discharge rates?

Yes, it’s essential to know LiPo discharge rates. If you somehow discharge the battery at a higher rate than usual, accidents can occur. So, with proper knowledge of discharge rate, you can get better battery life.

Is it recommended to fully discharge a LiPo battery?

No, it’s not recommended to fully discharge a LiPo battery. Fully discharging a LiPo battery can cause permanent damage to it. And the worst part is, the damage won’t be visible as it’s internal damage.
