Tested 1 out of 10 protection boards, worked justa as expected, nothing to say about the nickel strip really, overall a great experience with this seller. ### ⭐ 1.0 out of 5 stars NO GOOD *by E***R on Reviewed in the United States on January 31, 2022* These BMS cannot protect batteries from being over discharge. I used one of this and my battery went down to zero volt instead of 3.2 volt. Please use one to check if your BMS works as it used to be other wise your batteries will be damage. I don't recommend BMS module to any one. --- ## 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.vn/products/309653732-10pcs-1s-3-7v-4a-lithium-battery-protection-board-18650](https://www.desertcart.vn/products/309653732-10pcs-1s-3-7v-4a-lithium-battery-protection-board-18650) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-24*
