    How to use Lipo battery connector? DIY Guide


    Lipo battery connector
    An interesting feature of lipo battery connector is that they perform more efficient ion exchanges when heated. If you've never noticed, your drone seems to gain more power after a couple of minutes; what is occurring is the increase in ion exchange efficiency once the battery heats up.

    From today, if you will be flying during the winter period, you should try to keep your LiPo batteries in a warm place before flying.


    Now that I've bored you to death with the basics of lipo battery connector, it's time to get into the main topics. First of all, LiPo batteries are distinguished on the basis of different judgments, in particular for voltage, capacity and discharge time.

    These are the three main features to look out for when buying your new battery.

    Battery voltage information

    Unlike NiCads and NiMHs which has a nominal voltage is for 1.2 volts per cell. LiPo batteries lipo battery connector has a nominal voltage of 3.7 volts per cell. The advantage is that fewer cells are used per battery, and in some cases on small drones, a 3.7 volt LiPo cell is all that is needed to power the model and fly it.

    Normal drone LiPo batteries have at least two or more cells hooked up in series to provide higher voltages. For large drones that need a lot of power, the number of cells is higher than 6. Here is the table that differentiates LiPo RC batteries.

    CAPACITY: How much energy the battery can hold?

    For example, a 1000mAh lipo battery connector that would fully discharge is in one hour with a discharge current of 1000 milliamps on it. If this same battery had a voltage of 500 milliamps, it would take 2 hours to fully discharge it.


    In summary:  if you want more flight time you have to increase the capacity of your battery. Of course due to size and weight (two factors that decide whether or not a drone can fly), you will have to stay within a certain range of battery capacity as more capacity means more weight and more occupied area.

    Battery will indicate the discharge time

    Discharge time is simply how fast a battery can be safely discharged with lipo battery connector. Remember the paragraph about ion exchange? Here:

    How quickly ions can flow from the anode to the cathode in a battery will indicate the discharge time. In the world of LiPo drone batteries it is called the “C “rating.

    What does it mean?

    The word C capacity starts with “C “, and this already should give you an idea. A battery with a lipo battery connector rating of 10C means that (theoretically) you can safely discharge it at 10 times faster than the battery capacity, at 15C = 15 times more, at 20C = 20 times more, and so on. ...

    The higher the C-score, usually the more expensive and heavier the battery will be. Avoid batteries with low C discharge ratings or you will damage the battery and possibly you’re ESC.

    As a very general guideline, 25C / 30C is typically for most 250-450mm drones. For larger drones, 30C / 35C are a safe choice. For the more aggressive FPV pilots, this number goes up even more.


    Reading your LiPo's temperature in degrees centigrade (°) after a flight is a good way to gauge if you are using a suitable C-rated battery. The general rule is that if you can't hold a lipo battery connector in your hand after use… you better change the battery!

    This is equivalent to a temperature above 50 °. 50 degrees is too much for me. Try to avoid temperatures above 40 °. So, if your LiPo batteries are very hot after use, consider purchasing a new battery with a higher discharge rating.

    Would you ever leave your child or dog locked up in the car on a sunny summer day?

    Here, avoid doing the same with LiPo batteries! The interior of a vehicle can reach well over 40 °; a LiPo that is stressed to such an extent will be damaged and will not last long.

    If you are flying in a very hot environment, it would not be a bad idea to keep your lipo battery connector fully charged in a cool place with the right temperature.


    If you want to avoid irreversibly damaging your batteries, avoid reaching a number below 3.0 volts per cell under charge. Even if you have a 60C battery and can only draw a quarter of that amount of power.

    If you hit the famous <3 volts per cell, the battery will quickly change its core temperature and its lifespan will drop substantially.

    Cards allows parallel charging

    There are cards on the market like the one in the picture that allow the batteries to be recharged in parallel. When connecting the batteries in parallel, exactly as seen above, the voltage remains the same while the overall battery current will be the sum of all the batteries.

    For example, if you connect 4 4S (i.e. 14.8V) 1500mAh batteries together, you will get a 4S (i.e. 14.8V) 6000mAh battery.

    Also be careful to choose a sufficiently powerful power supply and lipo battery connector.

    In fact, considering the battery above, (made up of 4 batteries in parallel), to recharge it at 1C .You will need a power supply and charger capable of delivering a power equal to P = V * I = 16.8 * 6 = 100.8W

    How to recharge in parallel?

    1. The batteries can only be connectedto the board when they are at exactly the same voltage of lipo battery connector (maximum 0.02V / cell difference)
      For this reason I recommend that you first connect the batteries one at a time to the charger or to the Battery meter and write down the voltages of all the batteries. , and then connect them to the card only when you are sure they are at exactly the same charge.
    2. always connect the XT60 cable firstand then the balancing cable
    3. Set a charging current equal to the sumof the battery capacities to recharge at 1C (if the batteries are all identical)

    A good rule of thumb here is the "40-80 rule". You can easily extend the overall battery life with a simple trick: charge with lipo battery connector just over half, between 40 and 80%.
