The lipos are fine. For the price I can't complain. Not sure why after multiple reviews with the same problem Amazon can't contact the seller to help its customers? The problem seems to be rust on the USB contacts. ### ⭐ Fake *by A***T on Reviewed in the United Kingdom on 11 October 2018* Batteries are 380mAh not 400mAh . Under the sticker printed real battery capacity. ### ⭐⭐⭐⭐⭐ Excellent product does exactly as described no hidden features *by A***R on Reviewed in the United Kingdom on 6 May 2018* Excellent product does exactly as described no hidden features, extended the use of the appliance by 4 times and good charger, so happy customer! --- ## 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/49063815-4pcs-3-7v-400mah-li-po-battery-for-hubsan-x4](https://www.desertcart.tn/products/49063815-4pcs-3-7v-400mah-li-po-battery-for-hubsan-x4) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-15*
