Gens ace 3800mAh 7.4V 2S1P TX Lipo Battery Pack with JST-SYP Plug for The QX7

Works great, which means it's a battery and does its job. Chat GPT says this battery will last for 30-45 hours in the Radio Link RC6GS Transmitter, which by any standards is a super long time before a recharge is necessary. Price is decent, light weight, fast delivery, It fits in the receiver battery compartment; I added some filler material(folded paper towel) to keep the battery from moving/sliding around in the compartment.

Ok so if you've got the QX7 and the NiMh 6s pack you will know its usual discharge rate til you need to recharge it is pretty decent. This 2s lipo blows it out of the water with about twice to three times as long of in-use charge time. I try to fly every day and this battery will last me over a week probably close to another one before charging is needed again. And that's flying my 5" quad, my tinyhawkfreestyle 2, tyro79, and the nanohawk---several packs per quad. I am going to try to get another one of these as a backup in case anything happens I will not be out of commission. It fits in the battery well with a lot of space left over and is the perfect thickness to seat properly and not jiggle around once the backplate of the QX7 is reattached. Definitely worth every penny, outstanding value.

My Spektrum DX8 needed a new 2s battery to replace my old lipo. It's been 6 months and this new lipo is working great. Fit nicely into battery compartment. Holds a charge forever. Definitely recommend.

Previous 2S 1800mAh Lipo battery at the end of morning and afternoon R/C Sailing Regatta race sometimes would almost deplete the battery. This GenAce has plenty of capacity, fits into the Spectrum DX6e Transmitter case snugly.

YMMV but unfortunately this battery is a tad too thick to fit in my Radiolink RC8X. Otherwise works perfectly as intended.
