I wouldn't buy again. *by J***E on Reviewed in the United States on January 3, 2018* The batteries seem to work and take a charge. But the charger is solid piece of junk. The 5 volt power port is poorly soldered onto the board and broke as soon as I tried to plug in a cord. ### ⭐⭐ The charge biggest POS didn’t even get to use it *by E***C on Reviewed in the United States on January 3, 2018* I’m giving it the benefit of the doubt with the Assumption that the batteries are good the charger broke as soon as I try to put the USB into it the correct way it just pushed and I’d rather spend five or $10 more knowing the Chargers not going to break before I even get to use it ### ⭐⭐⭐⭐ Batteries work great *by K***7 on Reviewed in the United States on January 18, 2018* Batteries were cheap and work as well as the original that came with my drone.The charger died after the first use - wouldn't turn on again - so one star loss for that. --- ## 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/51296917-5-pcs-3-7v-750mah-25c-upgrade-lipo-battery-jst](https://www.desertcart.tn/products/51296917-5-pcs-3-7v-750mah-25c-upgrade-lipo-battery-jst) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-26*
