Newbie doesn’t want to set his house on fire...

Hi all,

New to FPV, just bought a receiver (FrSky Taranis X9D plus special edition 2019) so I can get some hours in on a simulator before starting a build.

Also new to Lipo batteries, and want to make sure I’m using them properly.

I bought a battery to go with the Taranis, it’s a 2S which I understand is the correct type, specifically: RX 7.4V - 17.8 Wh 2400 mAh.

Can someone help confirm the correct settings I should be programming into the receiver? Is this correct? (see attached).

Appreciate any help in advanced.

Cheers!

Looks good to me. 99% sure this only effects the battery percentage and low battery warning on the transmitter but your charger is what matters so long as it has low voltage detection and is limited to current less than the max charge current for your cells then you're in good shape.

So long as Li-ion doesn't get below 3.0V it can typically be safely recharged, around 2.5V there is a quick drop off to near 0V if you hit that "cliff" most chargers won't attempt charging the battery since the cell is probably very damaged and could catch fire from charging at that point. For batteries in a transmitter I'd take them out around 3.2V (there is some voltage sag based on the draw, more current or power pulled from the cells more the voltage dips temporarily and will recover when you disconnect or remove the current load). For lipos I typically bring them down around 3.6V per cell (no lower, and charge up to 4.2V) since higher load of motors can dip the cells .5V or more if punching out (on a 4S).
