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. ### ⭐⭐⭐⭐⭐ Great Lipo for my DX8 *by P***5 on February 23, 2024* 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. ### ⭐⭐⭐⭐⭐ You won't regret this battery it rocks *by A***H on March 18, 2021* 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. ## Frequently Bought Together - Gens ace 3800mAh 7.4V 2S1P TX Lipo Battery Pack with JST-SYP Plug for The QX7 - Radiolink RC6GS V3 7 Channels RC Transmitter and Waterproof Gyro Receiver R7FG, 30 Models Storage 2.4Ghz Voltage Telemetry Surface Remote Radio Controller for RC Crawler, Drifting, Car and Boat - Radiolink R4FGM V2.3 4 Channels Tiny RC Gyro Receiver for Mini RC Cars 1/28 and Boats, 3-10V High Voltage Servo Support, Long Control Distance for Radio RC8X RC4GS V3/RC6GS V3/T8S/T8FB --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/101580750-3800mah-7-4v-2s1p-tx-lipo-battery-pack-with-jst](https://www.desertcart.vn/products/101580750-3800mah-7-4v-2s1p-tx-lipo-battery-pack-with-jst) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-20*
