Review: Work well in a Quadrone Tumbler - I've got a Quadrone Tumbler Cam that my gf bought for her grandson but decided it might be a little more than he could handle at his age. I wanted to try a drone for awhile so I tried it. It was strange and the battery wore out too quick to get a good feel for it so I looked around and decided to try these since they were as close in size as the original, just a bit fatter and a little shorter. A bit tight going in but they're short enough that there is enough room. All charged up relatively quickly an, so far, the batteries last longer than the original. With 7 batteries now, I can take the drone somewhere with a bit more space and less trees and make the trip worth it. I'm guessing I can get at least an hour and if I use my auxiliary battery and plug them in right after they're used up, that may be even longer as they seemed to charge pretty quickly. One warning. I pushed one in pretty far and had a hard time getting it out. They seem to connect pretty easy to its charger. Also for anyone with a Quadrone, at least out of the box, they were a bit harder to disconnect from the drone after used up. That may change with use. Review: Barely as good as stock 500mAH - Batteries are marked 720mAh 20C - both numbers are an exaggeration. These batteries are worse than stock while being advertised as an upgrade. Flight times are 5 to 7 minutes at best with easy moderate throttle use. Can’t recommend these at all. Very disappointing. ## Features - ●Longer Flight Time:Capacity of 720mAh can bring you longer flying time than the original 500mAh battery,Upgraded battery offers more power,more safety and higher performance for your quadcopter. - ●Batteries are Suitable for: Syma X5,X5C,X5C-1,X5SC,X5SC-1,X5SW,X15,X15W and Cheerson CX-30W UDI U45 RC Quadcopter,no modification necessary. - ●6 in 1 Multi Output Charger:Voltage input:DC 5V; Voltage output: 4.2V ,charging 6 batteries at one time,save your time,with built in protection IC,over charge protection short circuit protection,this charger compatible with most Micro RC Quadcopter batteries: UDI U815, U816,U816A,U818A; Wltoys V929, V949, V959; Syma X1,X4,X5,X5C,X5SC,X5SW; MJX T04, T05, F28, F29; Hubsan H111, H107L, H107C, H107C-HD, H107D and more. - ●Quality Guarantee:Batteries come equipped with built-in protection mechanism for safe charging and use. - ●Numbering Space:Dedicated space for battery numbering,allow for easy management,you can keep track of what is charged and what needs to be charged. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01LOC09Z8 | | Brand | HEIOKEY | | Customer Reviews | 4.1 out of 5 stars 87 Reviews | | Input Voltage | 5 Volts | | Manufacturer | ECOGREEN | | Mfr Part Number | EGB-01X5 | ## Product Details - **Brand:** HEIOKEY - **Input Voltage:** 5 Volts - **Manufacturer:** ECOGREEN ## Images ![HEIOKEY Upgrade 6Pcs 3.7V 720mAh 20C Rechargeable Lipo Battery with 6 in 1 Battery Charger for Syma X5 X5C X5SC X5SC-1 X5SW X5C-1 UDI U45 U45W RC Quadcopters Drone - Image 1](https://m.media-amazon.com/images/I/61EwBJqEQVL.jpg) ![HEIOKEY Upgrade 6Pcs 3.7V 720mAh 20C Rechargeable Lipo Battery with 6 in 1 Battery Charger for Syma X5 X5C X5SC X5SC-1 X5SW X5C-1 UDI U45 U45W RC Quadcopters Drone - Image 2](https://m.media-amazon.com/images/I/61wn-2L-znL.jpg) ![HEIOKEY Upgrade 6Pcs 3.7V 720mAh 20C Rechargeable Lipo Battery with 6 in 1 Battery Charger for Syma X5 X5C X5SC X5SC-1 X5SW X5C-1 UDI U45 U45W RC Quadcopters Drone - Image 3](https://m.media-amazon.com/images/I/712sMRZimAL.jpg) ![HEIOKEY Upgrade 6Pcs 3.7V 720mAh 20C Rechargeable Lipo Battery with 6 in 1 Battery Charger for Syma X5 X5C X5SC X5SC-1 X5SW X5C-1 UDI U45 U45W RC Quadcopters Drone - Image 4](https://m.media-amazon.com/images/I/61WaTzaQ8gL.jpg) ![HEIOKEY Upgrade 6Pcs 3.7V 720mAh 20C Rechargeable Lipo Battery with 6 in 1 Battery Charger for Syma X5 X5C X5SC X5SC-1 X5SW X5C-1 UDI U45 U45W RC Quadcopters Drone - Image 5](https://m.media-amazon.com/images/I/61G5JyfVjnL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Work well in a Quadrone Tumbler *by J***R on June 29, 2017* I've got a Quadrone Tumbler Cam that my gf bought for her grandson but decided it might be a little more than he could handle at his age.

These batteries are worse than stock while being advertised as an upgrade. Flight times are 5 to 7 minutes at best with easy moderate throttle use. Can’t recommend these at all. Very disappointing. ### ⭐⭐⭐⭐ Nice Batteries *by J***J on March 27, 2017* What I like about these is that they give power fast (20c rating is good). I also like the charger, the batteries don't fall out, seem to charge fast enough, and don't get hot. They also don't get hot when discharged fast. What I am not sure about is the 720mAh rating. I only get about 8 min for a JJRC H31 (modified! Will not fit a stock H31!). A little disappointing, but they have lots of power and give it fast while they last. --- ## 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.tn/products/35833075-heiokey-upgrade-6pcs-3-7v-720mah-20c-rechargeable-lipo-battery](https://www.desertcart.tn/products/35833075-heiokey-upgrade-6pcs-3-7v-720mah-20c-rechargeable-lipo-battery) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-20*
