Review: Great batteries and charger for my quad copter - Batteries and charger are great. I replaced batteries of my dromeda quad copter. They last in flight longer and are slightly lighter than originals. Charger works great on 1-4 at a time Review: Great batteries, Bleh charging splitter - Batteries 5-star: they work as well or better than Holy Stone batteries at a lower cost Charging Station 2-star: Battery adapter plugs too loose in receptacles. Ports & lights uncorrelated. USB cord too short. Overall, it works, but poor design. UPDATE Apr 15, 2018: The seller (Three Stone) reached out to me in regard to my dissatisfaction with the charger. They offered me a replacement charger along with four more batteries, no return necessary. Very generous, indeed. Once again, the batteries are all great. While the charger could be improved (see above comments), it does work. Based on seller responsiveness and the superb quality of the batteries, I'm increasing my review to four stars. Once again, the batteries by themselves are 5-star. ## Features - Best Choice as Chirstmas Gifts: Exquisite and Thoughtful package,High Cost-effective Battery.Enough Power for your flight.

I replaced batteries of my dromeda quad copter. They last in flight longer and are slightly lighter than originals. Charger works great on 1-4 at a time ### ⭐⭐⭐⭐ Great batteries, Bleh charging splitter *by A***R on April 2, 2018* Batteries 5-star: they work as well or better than Holy Stone batteries at a lower cost Charging Station 2-star: Battery adapter plugs too loose in receptacles. Ports & lights uncorrelated. USB cord too short. Overall, it works, but poor design. UPDATE Apr 15, 2018: The seller (Three Stone) reached out to me in regard to my dissatisfaction with the charger. They offered me a replacement charger along with four more batteries, no return necessary. Very generous, indeed. Once again, the batteries are all great. While the charger could be improved (see above comments), it does work. Based on seller responsiveness and the superb quality of the batteries, I'm increasing my review to four stars. Once again, the batteries by themselves are 5-star. ### ⭐⭐⭐⭐⭐ Non-functional right out of the box *by R***S on February 15, 2018* Upon receiving I charged all 4 batteries. I plugged the charger into a USB port on a power strip and all the charging lights lit up without any batteries connected so I plugged it into a USB adapter plug and the lights worked accordingly. 2 of the 4 batteries after the initial charge (took about 1.5hrs) worked as advertised. Not a noticible increase in flight time (Holy Stone 181w drone) from original batteries (750mah). The other two did not take a charge, the low battery lights on the drone began to blink within 5 seconds of turing it on and didn't have enough power to even turn the rotors. After i used the 2 good ones I took all 4 and put them through another charge cyle. This time none of the 4 held a charge and all of them showed low power withing a few seconds of turning on the drone. Basically paid $20 for 20 min of flight time. $1/min a little steep for playing with a toy. It sucks because it's a phenomenal drone but I haven't found batteries that are functional in the least. The original batteries lasted a month before they did the same thing as these. Update: Increased to 4 stars due to their top notch cutomer service. Once I get the replacement batteries I will upgrade to 5 stars if they're functioning. Updated to 5 stars as they sent me new batteries and they work well, can definitely see the difference in performance from the original 500mah batteries Their customer service is excellent and follow up to ensure satisfaction. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/46363691-engpow-3-7v-850mah-lipo-battery-with-x4-battery-charger](https://www.desertcart.tn/products/46363691-engpow-3-7v-850mah-lipo-battery-with-x4-battery-charger) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-03*
