Dealing with rc helicopters batteries

You need to learn how to deal with rc helicopters batteries. Disassemble the battery packs and reassemble put some spacers between the cells so that air can circulate. The batteries should not be stored loaded on top. Neither should be completely discharged, because for we risk self-discharge to lower 2.7V per cell. Get to know tips to ensure maximum capability.

According to the manufacturer never has to discharge the battery below 2.7V per cell. Because between 2.7 and 2.9 there is very little energy (only 30 seconds to fly over) and the load below 2.9 is very slow, you should not lower than 2.9 volts per cell.

What you must do

Ideally, always follow these recommendations. Some are not possible or practical to follow them forever, but we can do sometimes. We follow the same order as in the previous sections. In addition:

      Buy rc helicopters batteries in places where they sell many, so we have plenty of guarantee that are of recent manufacture. Use trusted sites with a high level of rotation.

      Try to keep them in a good balancer (not recycler). Are preferable what they charge each cell independently, rather than those who download all the cells to the same level.

      We should charge the battery at 0.5C. But take two hours to charge and this is not practical in the field of flight. But if we can do it at home, there is no need to hurry.

If rc helicopters batteries have equal sides is advisable to buy another charger and another pack. That would allow us to upload them to 0.5C flying the same. It is advisable to take the batteries charged from home, having got charged 0.5C during the previous night. The discharge of the battery should go far enough for our engine. Unfortunately, this requires more capacity to buy batteries, but bulky and heavy. It may be good for a competition that can be counterproductive, but for normal flight it can be very advisable.

We can keep the batteries in the refrigerator in a sealed bag. Then we will put them in a cool place, not over the monitor. It is advisable not to charge the batteries when they are at home, but do it the day you're going to use rc helicopters. In most cases, we will deal mainly lithium polymer battery.  These are often used in radio control models or other applications requiring high discharge.
