The batteries don’t last long but they are the same value as the original batteries. I just doubled her play time by having 4 batteries instead of just two. The batteries are just as powerful and comes with a charger. Good functionality. ## Frequently Bought Together - Blomiky 2 Pack 7.4V 1200mAh Li-ion Rechargeable Battery with SM5P Plug and Charger Cable for R208 R308 2008 RC Boat R208 Battery 2 - DEERC RC Boat with LED Light, 30+ Mins, Self Righting Remote Control Boat for Pools & Lakes, 20+ MPH, 2.4GHz Racing Boats, 2 Battery, Pool Toys for Kids, Radio Controlled Watercraft - RC Boat 30KMH with 7Light Modes,Remote Control Electric Fast Speed Boat for Adults Kids 8-12 Lake Pool Water Play,Self-righting,Demo,Water Cooling,Full Waterproof,20 Mins,Low Battery Alert,2.4Ghz,Red --- ## 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.kr/products/449479558-blomiky-2-pack-7-4v-1200mah-li-ion-rechargeable-battery](https://www.desertcart.kr/products/449479558-blomiky-2-pack-7-4v-1200mah-li-ion-rechargeable-battery) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-08-30*
