My project continues. ### ⭐ Junk: do not buy, no seller replies *by H***S on Reviewed in the United States 🇺🇸 on June 4, 2018* One star because there is not a no star rating. Don’t get me wrong I expected cheap and was pleased the unit promptly lit up ready when batteries installed, but then closed the box and because the board was warped it sheared parts off the board and quit working. No reply to complaint. Junk do not buy. --- ## 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.sn/products/92579204-3s-18650-lithium-battery-box-12v-output-detachable-welding-free](https://www.desertcart.sn/products/92579204-3s-18650-lithium-battery-box-12v-output-detachable-welding-free) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-06-01*
