Use in reference to Lithium Polymer batteries, commonly used for their excellent energy density and their ability to provide large currents.
Alternatives to LiPo batteries
LiPo is often the first choice of battery due to its high discharge rate and high specific energy (100 - 265 Wh/kg), defined as its energy per unit mass. In terms of these two characteristics, what ...
Is it safe to fly LiPo batteries after they get "puffy"?
Some of my LiPo batteries got "puffy" after a few months. Is it still safe to fly them, or should I safely dispose of them?
At what current should I charge a LiPo battery?
I have several different LiPo batteries which I use with my drones, many of them are different voltages and different capacities. How do I know at what current I should charge my drone LiPo batteries?
In what situations do puffy batteries pose a risk of ignition?
In this Drones and Model Aircraft SE question, Is it safe to fly LiPo batteries after they get "puffy"?, David O. asked if it is safe to use puffy LiPo batteries. Gparyani provided an ...
How can I safely parallel charge my LiPo batteries?
I have multiple LiPo batteries that I want to charge up so I can get out flying as fast as (safely) possible. With my existing LiPo charger, how can I parallel charge multiple batteries at once?
How do I safely dispose of my LiPo batteries?
I have an old LiPo battery that is nearing the end of its life, how can I dispose of it safely?
How low can I safely discharge a LIPO battery during flight?
What is the minimum voltage I can safely discharge a LIPO battery during a flight? For example, if I have a 3S LIPO battery, should I be aiming to land my RC plane before the battery gets below a ...
What is a safe amount of time a LiPo pack can be kept fully charged before it is discharged to storage capacity?
Is there any research that shows the actual decrease in capacity/performance/longevity of high discharge current LiPo batteries, like those used in quadcopters, depending on the total time they spent ...
Do low temperatures damage LiPo batteries?
I'm wondering if low temperatures affect LiPo batteries in any way? Can colder temperatures damage the cells? Can I store my batteries in bat safe box outside, in cold/hot temperatures?
How to restore LiPo-powered aircraft that have not been flown for years?
I have a bunch of relatively inexpensive battery-powered radio-controlled aircraft that I haven't flown in over a year. I haven't flown some of them in over 3 years. The aircraft are airplanes, ...
What are the conditions for LiPo battery damage from undervoltage?
It is widely known that Lithium-polymer cells are permanently damaged if their voltage drops below a certain threshold, around 3.0 volts, but I couldn't find much on the exact conditions and factors ...
At what voltage per cell should I store a LiPo?
Some sources say you should store your batteries at 3.85V per cell, other says it should be 3.7V. My charger (ISDT Q6 Lite) on the "Storage" mode has a thumbs-up mark at 3.7V, probably indicating ...
Determining the mAh of 4S battery for a 3 inch drone
I have a 3" drone frame, flight controller that can take 3S or 4S LiPo, and 1507 4200KV motors. How do I find the right capacity of battery to purchase? Should I purchase 4S 850mAh or 4S 1500mAh? And ...
Series or parallel connection for drone batteries?
What is the difference between adding two drone batteries in series vs a parallel connection for flying the drone?
