Turnigy Nano-tech 2100mAh 2S1P 20C LiFePo4 Transmitter Pack (Futaba T14SG & 4PK)

I have been looking for a Taranis battery pack for quite some time now and I finally got this. I'm extremely satisfied with my decision. It fits snug inside the cover. The 2 cell LiFe with 2.1 amps holds good for at least 2 days when I use it a bunch. For everyone who has a Taranis X7, go for this battery.I have been using it for a couple of months now and I've no cons to report as of now.

I took out the AA tray and wired a connector to fit this Battery. Great mod!!

These are a game changer so you dont have to keep feeding the transmitter AA batteries. Holds a charge for a long time, and not nearly as volatile as lipos. Fits perfect in my Futaba 4PV.

After some minor trimming and connector mods on my TX, this this fits nice and snug in the battery compartment of my DX5C. No more massacre of AA batteries every other day. AWESOME!

I was skeptical but I've ran this battery through two major events and the voltage has only come down .1, from 6.8 to 6.7. I probably won't need to charge it in the next month. No more worrying about AA's in my 4PM.

Works perfectly in my 4PX. Supposedly comes at 30% charged and needs to be returned to storage charge. I didn't notice any issues even one cycle in. This pack MUST be charged outside of the radio as a LiFe battery.If you're unsure how to charge a LiFe pack do some research first, it is not the same as any other battery chemistry. You can and will damage your equipment or property using an improper charger.

Good value for the money, hopefully it will perform as advertised.

Just received the battery and it dropped right in. Perfect fit for the Futaba 4PK super-R. It even came charged to 6.7v. Time will tell how much clock time I get from this one but for $20 or so shipped, the price was cheaper from Amazon than through Hobbyking's online site with shipping!!! Can't beat that with a stick! I just hope it holds up to the test of time.
