Some post reading about lipo We are moving to provide more lipo information in the forum
Understand the LiPo batteries are very volatile and dangerous. There have been many situations where such abused batteries have caught fire and burned down houses. Several radio controlled planes have caught fire and crushed because of these batteries.
A slow discharge is safe. Even if it goes all the way down, the battery will not catch fire. But the recharge face is where trouble may come in. At 3.0V, the dangers are significant and you must care. At 2.5Vs, most manufactures advice the battery is too dangerous and should not be recharged. Internal damage rate accelerates even further at 1V and below.
Step 2:- Get a smart charger
You need a good charger with balancing features. The charger must have the ability to control the charge current.
Step 3: Charging instructions
Just before you begin the process, here are a few things to note:
· Do not leave the batteries unattended. Monitor them constantly by feeling the battery heat with your hand.
· If it catches fire, let it burn outside in a safe area.
Step 4: Charge the battery
At this point, you need to be very careful to charge slowly. If the charge is below 3.0V, go at a rate of 1/20 C charge until it gets above 3.0.
You may require using a NiMh or NiCad charger setting. Most chargers have these safety features.
You can increase the speed to 1/10 – 1/5 C when the battery gets between 3.0 and 3.V. And when it gets above 3.7V, you can charge at 1 /2C until full charge.
Step 5: You are good for normal use
If the battery discharged too low, the internal damages are greater. But if the battery works ok, you are free to continue using it normally.
Dead LiPo battery disposal
Start by checking the warranty to ensure it has expired. Sometimes, a replacement is possible. And if that is not an option, here are disposal steps.
· Discharge it as low as possible. There are many ways to do this, including using computerized chargers.
· Place it is a water bath with salt water. Submerge the wires completely and continue adding table salt in the water until it can no longer dissolve. Leave it in the water for at least 24 hours.
· Check the voltage. You are looking for 0.0V. If you don’t have it yet, put it back into the water.
· Now you can throw it in the trash. LiPo batteries are not hazardous at this point, so the garbage can will do just fine.
Recharging a badly discharged LiPo battery should be handled very carefully. If you think you are not ready for the process, take it to the experts.
