What does LiPo discharge mean?
When a LiPo battery sits for a long period of time (and not at proper storage voltage), it tends to discharge itself. If it drops below 3.0V per cell, the vast majority of LiPo chargers will not charge it. Sometimes, batteries with this problem can be rehabilitated, but just as often, they are a lost cause.
What is a discharge test on a battery?
Charge/discharge cycle testing is one evaluation test method used to meet this demand. The test objective is to determine the number of times a battery can be used by evaluating it until it deteriorates after repeated cycles of charging and discharging.
Should you discharge LiPo batteries?
Never discharge a LiPo battery below 3.0v per cell. Ideally you never want to go below 3.2v per cell to maintain a healthy battery. 2.9v per cell and lower is causing permanent damage. Never leave your LiPo batteries sitting around on a full charge for more than 2-3 days.
What is the discharging rate of a LiPo battery?
A battery with a discharging rate of 95c, that means you could safely draw it at the 95 times more than the capacity of the pack, a 10C pack = 10 times more, a 20C pack = 20C times more, from above the picture, you can discharge at 95 times more than 1300mAh, here is the calculation below: 95C = 95 x Capacity (in Amps)=95*1300mAh=123500mAh=123.5Ah
How to maintain a LiPo battery for long time?
How to maintain the Lipo battery? 1 Before Charge. Please read the charger instruction book before charging. 2 Charging. Only use charger designed for lithium polymer/Lion battery. 3 Discharging. Never discharge Batteries at amperage rates higher than specified on Batteries’ labels. 4 Lipo Battery Storage:
What is the resistance of a LiPo battery?
All electrical components has resistance, even a piece of wire has resistance, so is a battery. The resistance in a battery is called internal resistance. As explained in my LiPo battery beginner’s guide, IR determines how effectively a battery can deliver current to your quadcopter.
What’s the difference between IR and LiPo batteries?
IR has to do with discharge rate too, for example if your battery is designed for low current applications with 10C rating, IR will inherently be higher. 18650 Li-ion batteries have much higher IR than typical LiPo batteries, so do not worry! How to Measure IR?
