Lithium Battery Selection Guide for Entry-Level Model Airplanes

Hello everyone, this time we will talk about how novices choose to combine model aircraft batteries.

Capacity: mah represents the capacity of the battery. Novices are recommended to choose one between 1000 and 1800 mah. This range will be more suitable and not too heavy. Commonly used ones are usually 1500mah or 2200mah. 2200mah 25c or 30c is relatively common. When choosing batteries, it is best to choose batteries with the same capacity. Don't buy one bigger and one smaller, because if the capacity is the same, the weight of the battery will basically be the same. This will be more practical since you will not need to adjust the center of gravity each time you change the battery.

S Number: Refers to the number of cells in the battery. Novices are recommended to choose 3S. Each battery cell is 3.7V and the total battery voltage of the 3S is11.1 V. When fully charged, it is usually 12.6 V.

C number: refers to the discharge rate. Basically what you see on the market are 25C, 30C and 35C. For fixed wings, 20-30C is enough. Battery requirements are not particularly high, unlike the time machine which requires high bursts. It should be noted that planes are different from cars. Airplanes have weight requirements, meaning if they are too heavy they cannot fly without carrying them. If the weight is too heavy, the flying effect will not be good. will be difficult to exploit.

Interface: It is best to use the XT60 interface. Do not use the old T-plug interface, which has been eliminated.

Price: If you have no financial pressure, just choose the higher version. But since most people are students and not very rich,they don't play games anyway, so they play alone. As long as battery quality is not an issue, choose the one that offers high performance. I now commonly use the ovonic 3S 25C battery.

Note: Avoid this low voltage. Generally, it should be charged when lower than 11.1V in 3 seconds. The problem that we novices often encounter is over-discharge and power loss, that is, the battery is completely discharged and the measured voltage is found to be too low, resulting in power imbalance. load. losses on the battery, which is very difficult. After repair, the battery will be discarded. So we need to be careful when using it.

Ask me about the problem with lithium batteries for model aircraft

Lithium batteries for model aircraft should be stored at a voltage of about 3 .85Vfor a long period. Fully charged or stored at. Low voltage will cause the battery to be discarded. This is to play the common sense model. Lithium batteries for model aircraft are all lithium polymer batteries, which have a low lithium-ion discharge coefficient and low cycle times. The best chargers have a battery repair charging mode.

After being left in place for 4 seconds, the voltage of the lithium battery T-plug of the model airplane was only 7.4V and it did not could be charged with the balanced load due to a low voltage alarm. What causes it to become 7.4 volts and how to deal with it?

In terms of pure charging capacity, the 4S 3700MAH has a bit more power.indicate. 25C and 30C are discharge rates.

6S 2200MAH 25C means 6 batteries are connected in series and the discharge currentmaximum is 25X2200, which is equivalent to 55A.

4S 3700MA 35C means that 4 batteries are connected in series, and the maximum discharge current is 35X3700, which is equivalent to 129.5A.

The over-discharge of the model's lithium battery in 4 seconds cannot be less than 10.2V. If it is as low as 7.4V, it means that serious damage has occurred. been caused and it is believed that this cannot be the case. be restored. For normal use, it should be charged when lower than 14.4V (it is recommended not lower than 13.2V, and it can reach 16.8V when fully charged) /p>

Lithium batteries are most afraid of over-discharge, so they must be charged in time. Excessive discharge will seriously damage the lithium battery, requires special attention.
