This is going to be the 2nd Part of the Recommended Battery Series for FrSky Transmitter X9D Plus Transmitter. Don’t get confused with the title that FrSky X9D 2019 requires different batteries than x9d plus as you might think there are some changes in the battery compartment of it. But that is not the case. in fact, the battery compartment of X9d 2019 is exactly the same as of old Taranis X9d Plus. 

However, there is a special reason why this article is focused on Taranis X9D Plus 2019 rather than focusing on X9d plus in general. It is because X9D 2019 only supports operating voltage between 6.5v to 8.4v, which is basically a 2S lipo or Li-Ion. But, the older x9d plus (SE also) supports a wide range of operating voltage between 6 to 15V which means it can support even a 3s Lipo or Li-ion. 

FrSky Taranis X9D 2019 has also some other difference with older Taranis X9D when it comes to battery and charging. Older Taranis X9D plus has a Ni-Mh battery charging circuit that allows you to charge the stock battery with a charger that comes with it. Please note that the charging circuit is specifically for 6 cell Ni-Mh batteries and do not try to charge any other batteries like Li-Po or Li-ion in it. It is recommended to use the FrSky Ni-Mh with the charger if you are planning to charge the battery without actually removing the battery from the radio.

When it comes to X9D Plus, it only supports 2S batteries, and you might think about using the Ni-Mh battery with it. Of course, you can the Ni-MH battery in it. But don’t think to charge the battery using the transmitter, DON’T DO IT!!! FrSky X9D 2019 transmitter has a 2S lithium battery charging circuit in it that supports the charging through Mini USB Cable. 

That is specifically made for lithium batteries and above all, only for 2S batteries. Hence don’t charge the stock Ni-Mh battery using the supported USB charging in case you are going to use that battery in the New X9D 2019.  

Hence you can use the batteries that will fit in the Taranis X9D compartment for the FrSky X9D 2019 as well. In the last article, we have discussed FrSky Ni-MH 2000Mah battery, which is actually a good one. I still have a 4-year-old of that battery with me and it still performs well. So let's get our next candidate. 

3000mAh 2s X9D Li-Po

Check out this 3000mAh 2s Li-Po battery that you can find in amazon and Banggood is a great upgrade for the stock Ni-Mh 2000mah 7.2v battery. In Fact, this battery is specifically designed for FrSky X9D 2019 and other X9D radios as well.

When comparing it with stock Ni-Mh 2000mAh battery, this battery is 3000Mah 2 cell Li-Po. According to the theory, this battery should give you a 50% increased performance in battery life. But that is the only case if it got 3000mAh. However, this battery might disappoint you on that.

After running some tests to confirms the capacity, this battery is proved to be only around 2500mAh even though advertised as 3000mAh. Maybe the manufacturer is overstated it to attract buyers? Anyway, 2500mAh is still a good upgrade compared to the 2000mAh battery.

Usually, the capacity of Li-Po batteries is understated by the manufactures to compensate for any loss that might happen if they are stated as true which will basically give a good performance. So technically speaking, if you have a 1500mAh Lipo battery, the true capacity will be more than 1500mAh. It is usually around 50mAh extra for a 1500mAh Battery, So the battery will have an actual capacity of 1550mAh or 1600mAh.


Speaking of which, I thought this battery might be around 3100mAh or more, But I am disappointed in that point. Well, I am not disappointed with this battery, if that was the case then this battery won't has listed here. 2500mAh will give you a much better backup time than the stock battery. 

You can get around 6 hours of backup time with the stock Ni-Mh battery. With this 3000mAh battery, you can get around 10 hours of backup time which is indeed a worthy upgrade. When comes to the pricing, you will see it is pretty cheap. You can grab one from banggood or amazon for 15$ which is almost the same as of stock Ni-Mh battery.


How to Charge:

When it comes to charging, it is pretty easy and you don’t even need to take the battery out of it. How cool is that? FrSky X9D 2019 supports USB charging for 2S lithium-ion and polymer batteries. If the balance cable of the battery is plugged into the transmitter for powering it, you are all ready to go. Plugging the mini USB cable will charge it and you can use flawlessly.


If you are using it with the old Taranis X9D plus, then you will need to use a Balance charger for it. You can buy a JST to XT60 connector and charge it with the charger that you use to charge your regular Li-Po’s or Li-ion’s.



We have briefly discussed one of the popular but cheap alternative replacement battery for FrSky X9D. Well, it is not branded, but it will do the job. Hope this article has helped some to know about this replacement battery available for Taranis radio. In the next article, we will come up with another candidate. Stay Tuned!
