What’s Good about this LiPo?
The stock battery is a Ni-MH 7.2V 2000mAh battery, while this upgrade battery is a 2-cell 3000mAh LiPo. In theory it should give you a 50% boost in battery life. However when I ran tests to confirm the capacity (charging it from 3.4V per cell to 4.2V), I only got around 2500mAh, so the stated 3000mAh seems overstated.
Check out this guide to learn about the basics of LiPo battery.
This 2S LiPo is designed for the Taranis X9D (not compatible with QX7), it fits in the battery bay perfectly. It might also work in some other radios, as long as the voltage and dimension are supported :)
The physical size of the battery is 95x27x26mm.
Despite having a larger capacity, it’s also much lighter than the original battery (118g vs. 167g). With this LiPo installed, the radio feels much better in the hands.
I’ve been using the stock Mi-MH battery for over 4 years, it’s time for a new battery anyway :) So this LiPo seemed to be a good candidate.
What’s Not So Good…
Because it’s a LiPo battery, you need to “balance charge” it, and you cannot use the internal charger. That means you would have to take the battery out of the Taranis for charging. But given the longer run time, you probably won’t have to charge it as often.
If you don’t know what “balance charge” means check out my LiPo Charger Guide.
How about 3S Battery?
I thought about getting a 3S LiPo, but when you flash your receivers via the Taranis, you can fry them with the higher voltage. Therefore you’d have to power the receiver separately which isn’t convenient at all. So 2S makes more sense to me.
How about 18650 Battery?
Yes, It’s possible to use 18650 Li-Ion batteries too in the Taranis X9D.
Check the voltage of your pack before connecting – voltage should be around 7.6V. You might want to charge it first :)
The LiPo Battery connects to the radio by the balance lead.
Go to the Radio Setup page by holding down the menu button for 3 seconds, and set “Battery Meter Range” to something like 7.0V to 8.4V.
Finally calibrate the battery sensor under “Battery Calibration” against a multimeter for more precise reading.
