Lemon 5500mAh 4S 45C/90C Lithium Polymer Battery Pack

The Lemon 5500mAh 4S 45C/90C Lithium Polymer (LiPo) battery pack is a high-performance battery commonly used in remote-controlled vehicles like drones, RC cars, boats, and airplanes. Let’s break down what each specification means:

1. Capacity (5500mAh): This indicates the amount of charge the battery can hold, measured in milliampere-hours (mAh). In this case, the battery can store 5500 milliampere-hours of charge.
2. Number of Cells (4S): “4S” refers to the number of cells connected in series. Each cell provides a nominal voltage of about 3.7 volts, so a 4S battery pack has a nominal voltage of around 14.8 volts (3.7V/cell * 4 cells).
3. Discharge Rate (45C): The “C” rating denotes the discharge rate capability of the battery. In this case, 45C means that the battery can discharge at a rate that is 45 times its capacity. So, for a 5500mAh battery, the maximum continuous discharge rate would be 45 * 5500mAh = 247.5A.
4. Burst Discharge Rate (90C): This is the maximum discharge rate the battery can handle in short bursts. The burst discharge rate is often higher than the continuous discharge rate. In this case, it’s 90 times the capacity, meaning the battery can handle short bursts of discharge at up to 495A.

It’s important to note that while the burst discharge rate indicates the maximum current the battery can handle momentarily, continuous operation near this limit can degrade the battery’s lifespan and performance. So, it’s usually best to stay within the continuous discharge rate for regular use.
