Do I need to discharge LiPo before charging?

LiPo batteries also don't develop memory or voltage depression characteristics like NiCd/NiHm batteries, and do not need to be discharged before being charged. But they're not without their downside. Mishandling of these batteries can lead to fire, explosions and toxic smoke inhalation.

How often should you discharge LiPo batteries?

Never leave your LiPo batteries sitting around on a full charge for more than 2-3 days. If by the 3rd day you realize you are not going to use your battery today, you need to discharge your battery down to 3.6v-3.8v per cell for safe storage until you are ready to use the battery again.

Can you charge a LiPo right after use?

It's recommended to let it cool down first. No problem recharging right away. The packs will continue to cool during the charging process. Been doing this for years with no issues at whatsoever.

Why should I discharge my LiPo battery?

RE: Why discharge a LiPo? It is just there so that you can check the capacity of the battery. i.e. discharge, and then charge to see how many MAH's it will hold.

Can you charge and discharge a LiPo at the same time?

No, the battery is not charging and discharging at the same time. It can do one or the other but not both. When the charging system (solar panel or alternator) is below the voltage of the battery, the battery is going to supply the needed current. It can supplement the charge coming from the charging system.

How To Discharge Your R/C LiPo Batteries - Fast!

How many amps should I discharge my LiPo?

The maximum discharge capacity for that charger is 20 Watts. So, a 3S battery will, at peak charge, only be discharged at a little over 1.5 amps anyway, climbing up a little as the voltage comes down.

How do you fully discharge a LiPo battery?

Should lithium batteries be fully discharged?

Unlike other types of batteries that need to be recharged throughout their storage time, lithium batteries do better at 40%-50% DOD (depth of discharge). Pro-Tip: After every 30 charges, allow your lithium based battery to completely discharge before recharging. This helps to avoid a condition called digital memory.

When should LiPo be charged?

The safest way to charge a lipo battery and the one that puts the least amount of strain on your battery is to charge at a rate of "1C" or 1 times capacity. A 1C charge rate means that the current will charge the entire battery in 1 hour ( assuming you are starting with a fully discharged battery around 3.2v ).

What does 100C mean on LiPo battery?

1550mah 5s 100C: Max Current Draw = 1.55A x 100C=155A. 4500mah 6s 50C : Max Current Draw = 4.5A x 50C=225A. This means that we can discharge 155/230 amps continuously without damaging the battery. It may also be noted that increasing the C rating or increasing the battery capacity can increase Max Current Draw.

What voltage do you discharge LiPo?

For long term storage, the batteries should be discharged or charged, depending on their current state, to around 3.8v per cell.

Do I need to balance charge a LiPo?

So when charging LiPo batteries, usually you only have to adjust to the charge current. It's recommended to always use balance charging. Balancing chargers ensure that all the cells are charged evenly and there are no differences in voltages between them.

How do you keep LiPo batteries healthy?

How do you know if LiPo is fully charged?

Once the cells get to 4.2v, a smart charge will start lowering the amps while maintaining volts to top off the cells. Just leave them on there until they are done. A lipoly cell is typically considered to be fully charged when at a no-load voltage of 4.2 volts.

Can LiPos catch fire in storage?

They can catch fire if you charge them in the cold, then take them somewhere warmer which causes their voltage to rise above the safe level.

How long does it take to discharge a LiPo battery?

At 150W, it can discharge most FPV drone batteries in a matter of minutes. With this discharger, you can either discharge the battery completely, or set a voltage to stop the discharge (e.g. 3.80-3.85V per cell for storage). It is simple to use and even keeps all the cells balanced during the process.

What is the lifespan of a LiPo battery?

They give LiPos a typical life expectancy of 150 to 250 cycles. This is because the batteries heat up whenever they are in use, and many people discharge them lower than 3.0V per cell. Physical damage and water may also reduce their life expectancy.

How long does a 5000mAh LiPo battery last?

A 5000 mAH battery is quoted to last for about 20-25 minutes depending on the driving speed and your driving habits. However, there are several methods that you can do for making our battery last longer. It includes the usage of proper charge voltage and balanced charging.

Why is it important to avoid completely discharging a lithium-ion battery?

4: Avoid completely discharging lithium-ion batteries

If a lithium-ion battery is discharged below 2.5 volts per cell, a safety circuit built into the battery opens and the battery appears to be dead. The original charger will be of no use.

Why is full charge not allowed in lithium ion?

Li-ion does not need to be fully charged as is the case with lead acid, nor is it desirable to do so. In fact, it is better not to fully charge because a high voltage stresses the battery.

What is the fastest way to discharge a lithium battery?

Connect the most plug of the LiPo battery to the NiMH charger. Charge the battery with rock bottom possible current, like 0.1A. When the battery is charging, note of the voltage number that appears on the screen of the charger; once the amount reaches 3V unplug the battery immediately.

Can a discharged LiPo explode?

LiPo Battery Failures LiPo cells are susceptible to the same troubles of other lithium-ion cells; overcharge, over-discharge, over-temperature, short circuit, crush and nail penetration can all result in thermal run away and catastrophic failure leading to explosion and fire.

Why is my LiPo battery bloated?

In the case of LiPo batteries, the polymeric nature of the electrolyte means that they also tend to produce carbon dioxide (CO²) and carbon monoxide (CO) when they decompose. The production of these gases is what causes a LiPo battery to expand and swell.

How long does it take to charge a 5000mAh LiPo?

1C is usually a safe bet (5A for 5000mAh) if the battery manufacturer doesn't specify a maximum charging rate. 1C means that it will take about 1 hour to charge the battery from flat to fully charged.
