But this battery has worked perfectly for 6 months now. Just be careful when letting the battery get below 15F. Battery discharges and charges just like it is supposed to. --- ## 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/738328266-12v-7ah-lifepo4-battery-lithium-batteries-12v-with-7a-bms](https://www.desertcart.vn/products/738328266-12v-7ah-lifepo4-battery-lithium-batteries-12v-with-7a-bms) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-20*
