I have add on devices for protections. There are FOUR in PARALLEL in my bank of 12.8vdc @ 400 Amp Hours. I use a generic desertcart, robust 60 Amp Solar charger fed by 700 Watts of Renege N-type Solar Panels (3 200 W N-type + 100 W N-type) I live in the deep woods of the rainy Pacific Northwest in a clearing. My N-type panels provide adequate charging 80% of the time (supplemented with a gas gen feeding a VICTRON 30 amp 120vac charger. I've accidentally run the batteries to near zero and recharged them with NO adverse effects. Now a Renege Smart Shunt with remote panel has stopped over charging and discharging. The batteries live under my bed with a heat vent in Winter and A/C hose in Summer. VERY reliable and cost effective. Review: I believe 12V 100AM mini is a great battery. - I like how the 2 bolts and 2 washers do not separate which makes it very easy to change out. Very light weight for me. With the handles you can easily pick this up with one hand. I used this battery for about 10 full cycles and it charges to 14.4 or 14.5. Warning!!! before using LifePO4 batteries, know how they differ from Lead Acid Batteries. You can kill LifePO4 battery by discharging it and leaving it in the cold. Also, need to understand the BMS. For example, the BMS will shut off the battery after discount for 30 minutes before allowing you to charge it. I later bought the Dumfume 12v 300ah and just started using it. ## Features - 【314Ah Capacity for Extended Power】You will received 2 Packs of Dumfume 12V 314Ah LiFePO4 battery delivers a full 4.01kWh of energy, providing substantial power for long-lasting use.

Please use only a 14.6V LiFePO4 smart charger; using a lead-acid charger will damage the battery, and this will not be covered by our after-sales service. Compatible LiFePO4 chargers are available from our shop. **Q: Can I install and use it straight away upon delivery?** A: No, the battery’s charge level is ≤30% when it leaves the factory, and some charge will be lost during transport, so it is normal for the voltage to be low when you receive it. Please charge it fully before use. **Q: Can the battery be charged and discharged in cold conditions?** A: Battery operates normally from -20℃ to 60℃. Charging below 0℃ is forbidden to avoid cell damage. For winter outdoor use, warm battery indoors to over 5℃ prior to charging. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best Cost Effective ALL AROUND Lithium Iron Phosphate 12.8 volt battery available *by T***Y on January 12, 2026* These batteries have NO Bluetooth or temperature protections - but these "missing" features are made up in low cost.

Using 4 batteries in series for 48v service, saved wire size. --- ## 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.gr/products/788932975-dumfume-2-pack-12v-314ah-lifepo4-battery-with-200a-bms](https://www.desertcart.gr/products/788932975-dumfume-2-pack-12v-314ah-lifepo4-battery-with-200a-bms) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-08-25*
